                                 PROXY STATEMENT
                                       FOR
                         ANNUAL MEETING OF STOCKHOLDERS
                             TO BE HELD MAY 23, 2002

      This Proxy Statement is being furnished to the stockholders of BancFirst
Corporation (the "Company") in connection with the solicitation of proxies by
the Board of Directors of such corporation for use at its Annual Meeting of
Stockholders to be held May 23, 2002, and any and all adjournments thereof, for
the purposes set forth in the accompanying Notice of Annual Meeting dated April
26, 2002. This Proxy Statement and the accompanying form of proxy are first
being mailed to stockholders of the Company on or about April 26, 2002. THE
SOLICITATION OF THE ACCOMPANYING PROXY IS MADE BY AND ON BEHALF OF THE BOARD OF
DIRECTORS.

      The cost of soliciting proxies will be borne by the Company, including
expenses in connection with the preparation, printing and mailing of this Proxy
Statement and all proxy soliciting material which now accompany or may hereafter
supplement it. The solicitation will be made by mail; however, proxies also may
be solicited by personal interview, telephone and telegram by directors,
officers or employees of the Company. The Company will also supply brokers or
persons holding stock in their names or in the names of their nominees with the
number of proxies, proxy material and annual reports as they may require for
mailing to beneficial owners, and will reimburse them for their reasonable
expenses in connection therewith.

      The date of this Proxy Statement is April 26, 2002.

                       VOTING AND REVOCABILITY OF PROXIES

      The close of business on April 15, 2002 has been fixed as the record date
for the determination of stockholders entitled to notice of, and to vote at, the
meeting or any adjournment thereof. On the record date, there were outstanding
and entitled to vote 8,157,741 shares of the Company's common stock, par value
$1.00 per share (the "Common Stock"). Each share of Common Stock is entitled to
one vote. There is no cumulative voting with respect to the election of
directors.

      Under the provisions of the Oklahoma General Corporation Act and the
Company's Bylaws, a majority of the shares of outstanding Common Stock, present
in person or represented by proxy, shall constitute a quorum for purposes of the
Annual Meeting. Except as may be specifically required by the Oklahoma General
Corporation Act, the Company's Certificate of Incorporation or its Bylaws, and
other than the election of directors, the affirmative vote of the majority of
the shares of Common Stock present in person or represented by proxy at the
Annual Meeting and entitled to vote on the subject matter (a "Majority Vote")
shall be the act of the stockholders. For purposes of determining whether a
proposal has received a Majority Vote, abstentions will be included in the vote
total, with the result that an abstention will have the same effect as a
negative vote. For purposes of determining whether a proposal has received a
Majority Vote, in instances where brokers are prohibited from exercising
discretionary authority for beneficial holders of Common Stock who have not
returned a proxy (so-called "broker non-votes"), those shares will not be
included in the vote totals and, therefore, will have no effect on the outcome
of the vote.



      Common shares represented by properly executed proxies, unless previously
revoked, will be voted at the Annual Meeting of Stockholders in accordance with
the instructions thereon. If no direction is indicated, such shares will be
voted for approval of the matters submitted, and, in connection with any other
business that properly may come before such special meeting, such shares shall
be voted according to the discretion of the persons named as proxies.

      Any holder of the Common Stock of the Company who executes a proxy has the
continuing right to revoke the proxy at any time before it has been voted. Such
right may be exercised (i) by delivering written notice of revocation, bearing a
later date than the proxy card, to the corporate secretary of the Company; (ii)
by delivering to such corporate secretary a duly executed proxy bearing a later
date; or (iii) by attending the Annual Meeting and voting in person. Any holder
of the Common Stock of the Company may appear and vote at the Annual Meeting,
irrespective of whether he has previously given a proxy.

(1)   Shares shown as beneficially owned by David E. Rainbolt include 3,117,820
      shares held by R. Banking Limited Partnership, a family partnership of
      which Mr. Rainbolt is the general partner, and 11,513 shares held by the
      ESOP and allocated to the account of Mr. Rainbolt.

(2)   All of the shares owned by the ESOP are allocated to the accounts of
      participants, who direct the ESOP trustee as to the voting of such shares.

(3)   Investors Trust Company, an Oklahoma-chartered trust company, acts as
      trustee or co-trustee of various trusts which, in the aggregate, own
      666,921 shares. T. H. McCasland, Jr. and John C. Hugon, directors of the
      Company, are stockholders of Investors Trust Company and serve on its
      Board of Directors. Any voting or disposition of the Company's Common
      Stock by Investors Trust Company is determined by its board of directors.
      No attribution of beneficial ownership of shares included as beneficially
      owned by Investors Trust Company has been made separately to its board
      members or owners, all of whom disclaim beneficial ownership of shares in
      such capacities.

      Because of his position with the Company and his equity ownership therein,
David E. Rainbolt may be deemed to be a "parent" of the Company for purposes of
the Securities Act of 1933 (the "Act").

"Bank")), beneficially owned 4,199,577 shares of the Company's Common Stock

                              ELECTION OF DIRECTORS
                                (PROPOSAL NO. 1)

      Pursuant to provisions of the Company's Certificate of Incorporation and
Bylaws, the number of directors shall not be less than three nor more than 25;
currently, the Board of Directors consists of 19 directors. The Company's
Certificate of Incorporation and Bylaws provide for three classes of directors
serving staggered three-year terms, with each class to be as nearly equal in
number as possible. The Board of Directors has nominated Dennis L. Brand, C. L.
Craig, Jr., John C. Hugon, J. Ralph McCalmont, Ronald J. Norick, David E.
Ragland, and Joe T. Shockley, Jr. for election as Class I directors, with terms
expiring at the Annual Meeting of Stockholders to be held in 2005, or until
their successors are elected and qualified. Messrs. Craig, Hugon, McCalmont and
Shockley are incumbents whose current terms commenced upon their election by the
stockholders of the Company on June 24, 1999. Messrs. Brand and Ragland are
incumbents whose current terms commenced upon their election by the stockholders
of the Company on May 24, 2001. Mr. Norick was elected to the Board of Directors
on March 28, 2002. Proxies cannot be voted for a greater number of persons than
the number of nominees named. Other directors who are remaining on the Board
will continue in office in accordance with their previous elections until the
expiration of their terms at the 2003 or 2004 annual meeting, as the case may
be.

      The Board of Directors recommends a vote "FOR" the nominees for election
to the Board of Directors for the terms so specified.

      Subject to a quorum, the affirmative vote of a plurality of the shares
present in person or represented by proxy at the Annual Meeting and entitled to
vote is required for the election of directors. Abstentions and broker non-votes
have no effect on determination of plurality except to the extent that they
affect the total votes received by any particular candidate.

Rainbolt (Chairman). The Compensation Committee met once during 2001 to review
the compensation of the members of the Executive Committee, although it operated
on an informal basis throughout the year through discussions and actions at
regular Board meetings and through conversations with management and the other
directors.

      The Board of Directors as a whole administers the BancFirst Corporation
Stock Option Plan (the "Stock Option Plan").

of the Company subject to such filing requirements fully complied with such
requirements.

Compensation of Directors

      Each member of the Board of Directors receives a fee of $500 per quarter.

Compensation Committee Interlocks and Insider Participation

      During 2001, the Compensation Committee shared responsibility with the
Board of Directors for the development and implementation of the Company's
executive compensation policies. The Board of Directors delegated to the Chief
Executive Officer and the Chairman of the Board the responsibility for
determining the compensation of all executive officers other than the members of
the Executive Committee, the compensation for whom is determined by the
Compensation Committee. During 2001, the Executive Committee was composed of
Dennis L. Brand, James R. Daniel, K. Gordon Greer (Chairman), Robert A. Gregory,
David E. Rainbolt and H. E. Rainbolt, all of whom are directors and executive
officers of the Company. During such period, the Compensation Committee was
composed of J. R. Hutchens, Jr. and Melvin Moran, neither of whom are officers
or employees of the Company or its subsidiaries; H. E. Rainbolt, Chairman of the
Board of Directors of the Company; and William O. Johnstone, Vice Chairman.

      The Company purchases supplies and services from certain companies owned
by Pickard Limited Partnership, a family partnership of which David E. Rainbolt
is the general partner and H. E. Rainbolt is a limited partner. During 2001, the
Company's purchases of supplies, furniture and equipment from such entities
totaled approximately $148,000.

Report of the Compensation Committee and the Chief Executive Officer and the
Chairman on Executive Compensation

      The report of the Compensation Committee and the Chief Executive Officer
and the Chairman of the Board of Directors appearing below and the information
herein under "Company Performance" shall not be deemed "soliciting material" or
to be "filed" with the Commission or subject to the Commission's proxy rules,
except for the required disclosure herein, or to the liabilities of Section 18
of the Exchange Act, and such information shall not be deemed to be incorporated
by reference into any filing made by the Company under the Act or the Exchange
Act.

To our Stockholders:

      The Compensation Committee has primary responsibility for determining the
compensation of those executive officers who are members of the Executive
Committee, which includes the Chief Executive Officer and the Chairman of the
Board. The Chief Executive Officer and the Chairman do not participate in
discussions about their compensation or in the determination by the Compensation
Committee of such compensation. During 2001 the Compensation Committee of the
Board of Directors was comprised of J. R. Hutchens, Jr., Melvin Moran, William
O. Johnstone and H. E. Rainbolt (Chairman). Messrs. Hutchens and Moran are
nonemployee directors of the Company. The compensation of all other executive
officers is determined by the Chief Executive Officer and the Chairman of the
Board, pursuant to authority delegated to them by the Board of Directors, and in
consultation with the budget committee for the relevant operational area,
together with appropriate supervisory personnel.

                     General Executive Compensation Policies
                     ---------------------------------------

      The executive compensation policy of the Company is to provide a
compensation program that will attract, motivate and retain the high-caliber
executives necessary to achieve the Company's business strategies, while at the
same time ensuring that an appropriate relationship exists between executive
compensation and the creation of stockholder values. Each of the Compensation
Committee and the Chief Executive Officer and the Chairman applies this
philosophy in determining the compensation of the respective executive officers
over whom such committee or officers have responsibility with respect to salary,
bonuses and stock options.

      Each compensation element supports the Company's mission, values and
culture. The compensation principles that link the individual elements into an
integrated compensation strategy are as follows: (i) competitive compensation
within industry and peer companies; (ii) individual compensation correlated with
personal performance and stockholder value creation; and (iii) a compensation
structure that directly aligns the executives with the interests and concerns of
stockholders. Additionally, each executive officer's level of responsibility is
considered in setting executive compensation, meaning that the Company generally
pays greater compensation to persons having higher levels of responsibility.

      The Company's executive officers are paid base salaries that the
Compensation Committee and the Chief Executive Officer and the Chairman have
determined to be fair for their assigned responsibilities in comparison with
similar positions in other public companies in the banking industry. The
Compensation Committee and the Chief Executive Officer and the Chairman
periodically use surveys to assist them in establishing the base salaries of the
executives over which such committee or officers have responsibility for setting
compensation. The Compensation Committee and the Chief Executive Officer and the
Chairman make these comparisons in an effort to determine whether the Company's
executive compensation is reasonable and remains competitive enough to allow the
Company to retain skilled executives. The Compensation Committee and the Chief
Executive Officer and the Chairman of the Board believe that the compensation
paid to the Company's executive officers is in the median range of compensation
of executive officers of companies to which these comparisons are made. In
addition to making such comparisons and considering levels of responsibility,
the Compensation Committee and the Chief Executive Officer and the Chairman
consider individual performance and the Company's performance in terms of stock
price, earnings and cash flow. However, the determination of base salaries is
not strictly tied to performance criteria, and, in determining base salary
levels, the Compensation Committee and the Chief Executive Officer and the
Chairman believe that they afford approximately equal weight to each of the
factors described herein.

      The Company's executive officers, including the Chief Executive Officer,
participate in an Incentive Bonus Program. Bonus amounts earned are based on the
attainment of budgeted earnings and asset quality goals, and can

                                       11



be in amounts of up to 20% of the executive officer's base salary, depending
upon an objective review of the degree of attainment of such goals, as well as
both an objective and subjective review of the respective executive officer's
contribution thereto. Individual goals in each case are established by the
Compensation Committee or the Chief Executive Officer and the Chairman, as
appropriate.

      The Company's executive officers also are eligible to participate in the
BancFirst Corporation Stock Option Plan. Stock options provide executives the
opportunity to acquire an equity interest in the Company and to share in the
appreciation of the stock's value, thereby aligning their interests with those
of the stockholders. The Plan currently is administered by the Board of
Directors. In determining option grants, the Board does not take into account
the amount and value of options currently held, and the Company does not have a
target ownership level of equity holdings by its executives. During 2001, stock
options for 70,500 shares were granted to employees of the Company, at varying
exercise prices equal to the fair market value of the Common Stock on the date
of grant. No stock options were granted to any of the Named Executive Officers
in 2001.

                   Compensation of the Chief Executive Officer
                   -------------------------------------------

      In general, the Chief Executive Officer's compensation is determined by
the Compensation Committee in the same manner as that of the other senior
executives who are members of the Executive Committee, as described above. The
Compensation Committee believes that the compensation paid to David E. Rainbolt,
the Company's President and Chief Executive Officer, is in the median range of
compensation of the chief executive officers of companies to which the
comparisons are made. For 2001, the base salary of the Chief Executive Officer
was set at $205,000, an increase of $15,000 over his 2000 base salary. Mr.
Rainbolt also received a bonus of $15,375 in 2001. In making decisions regarding
CEO compensation, the Compensation Committee took into account results of
operations of the Company, conditions in the banking industry as a whole and Mr.
Rainbolt's contributions to the Company.

      The Internal Revenue Code limits the deductibility of certain compensation
expenses in excess of $1 million. This was not applicable to the Company for the
fiscal year ended December 31, 2001. However, the Compensation Committee and the
Board of Directors intend to monitor executive compensation levels and adopt
policies, as necessary, to obtain maximum deductibility of executive
compensation while providing motivational and competitive performance-based
compensation. The Compensation Committee and the Board of Directors will
continue to monitor the tax regulations to determine if any executive
compensation program changes are necessary.

       This report is respectfully submitted by the members of the Compensation
Committee, as well as by its Chief Executive Officer and the Chairman of the
Board:

     Compensation Committee:                 Chairman of the Board of Directors:

                          TRANSACTIONS WITH MANAGEMENT

      BancFirst has made loans in the ordinary course of business to certain
directors and executive officers of the Company and to certain affiliates of
these directors and executive officers. None of these loans outstanding are
classified as nonaccrual, past due, restructured or potential problem loans. All
such loans were made on substantially the same terms, including interest rates
and collateral, as those prevailing at the time for comparable transactions with
other persons, and did not involve more than the normal risk of collectability
or present other unfavorable features.

      Marion C. Bauman, a director of the Company, is a partner of Craig &
Bauman, a law firm located in Norman, Oklahoma that specializes in banking and
tax matters. From time to time Mr. Bauman and/or his firm has performed legal
services for the Company. During 2001, the dollar amount of any such services
provided by Mr. Bauman and/or his firm was not material to the Company.

      David E. Rainbolt is the general partner, and H. E. Rainbolt is a limited
partner of Pickard Limited Partnership, a family partnership, certain
subsidiaries of which sell equipment and supplies, and provide services to the
Company. See "Compensation Committee Interlocks and Insider Participation" for a
description of those transactions.

              RATIFICATION OF SELECTION OF INDEPENDENT ACCOUNTANTS
                                (PROPOSAL NO. 2)

      Arthur Andersen LLP ("Andersen") has been the company's independent
accountants since 1998 and at the recommendation of the Audit Committee of the
Board has been selected by the Board of Directors as the Company's independent
accountants for the fiscal year ending December 31, 2002. If the stockholders do
not ratify the selection of independent accountants, the Audit Committee and the
Board will reconsider the appointment. However, even if the stockholders ratify
the selection, the Board may still appoint new independent accountants at any
time during the year if it believes that a change would be in the best interests
of the Company and its stockholders.

                                       13



      Representatives of Andersen are expected to attend the Annual Meeting and
will have an opportunity to make a statement or to respond to appropriate
questions from stockholders.

      The Audit Committee reviews audit and, if applicable, non-audit services
performed by Andersen, as well as the fees charged by Andersen for such
services. In its review of any non-audit service fees, the Audit Committee
considers, among other things, the possible effect of the performance of such
services on the auditor's independence. No non-audit services were performed by
Andersen during 2001, and Andersen has advised the Company that they are
independent accountants with respect to the Company, within the meaning of
standards established by the American Institute of Certified Public Accountants,
the Independence Standards Board and federal securities laws administered by the
Securities and Exchange Commission.

      Additional information concerning the Audit Committee and its activities
with Andersen can be found in the following sections of this proxy statement:
"Board of Directors and Committees" and "Report of the Audit Committee."

Fees Paid to Andersen

      The following table shows the fees paid or accrued by the Company for the

                                                                              ========


      The Board of Directors recommends a vote "FOR" the ratification of the
selection of Andersen as independent accountants for the ensuing year.

                          REPORT OF THE AUDIT COMMITTEE

      The following report concerns the Audit Committee's activities regarding
oversight of the Company's financial reporting and auditing process.

      The Audit Committee is comprised solely of independent directors, as
defined in the Marketplace Rules of The Nasdaq Stock Market. The Board of
Directors has adopted, and annually reviews, an audit committee charter. The
composition of the Audit Committee, the attributes of its members and the
responsibilities of the Committee, as reflected in its charter, are intended to
be in accordance with applicable requirements for corporate audit committees.

      As described more fully in its charter, the purpose of the Audit Committee
is to assist the Board of Directors in its general oversight of the Company's
financial reporting, internal control and audit functions. Management is
responsible for the preparation, presentation and integrity of the Company's
financial statements, accounting and financial reporting principles, internal
controls and procedures designed to ensure compliance with accounting standards,
applicable laws and regulations. The Company's independent accountants are
responsible for expressing an opinion on the conformity of the Company's audited
financial statements to generally accepted accounting principles.

      The Audit Committee members are not professional accountants or auditors,
and their functions are not intended to duplicate or to certify the activities
of management and the independent accountants, nor can the Audit Committee
certify that the independent accountants are "independent" under applicable
rules. The Audit Committee serves a board-level oversight role, in which it
provides advice, counsel and direction to management and the independent
accountants on the basis of the information it receives, discussions with
management and the auditors and the experience of the Committee's members in
business, financial and accounting matters.

      Among other matters, the Audit Committee monitors the activities and
performance of the Company's internal and external auditors, including the audit
scope, external audit fees, auditor independence matters and the extent to which
the independent accountants may be retained to perform non-audit services. The
Audit Committee and the

                                       14



Board have ultimate authority and responsibility to select, evaluate and, when
appropriate, replace the Company's independent accountants. The Audit Committee
also reviews the results of the internal and external audit work with regard to
the adequacy and appropriateness of the Company's financial, accounting and
internal controls. Management's and independent accountants' presentations to
and discussions with the Audit Committee also cover various topics and events
that may have significant financial impact or are the subject of discussions
between management and the independent auditor. In addition, the Audit Committee
generally oversees the Company's internal compliance programs.

      The Audit Committee has reviewed and discussed the consolidated financial
statements with management and the independent accountants. Management
represented to the Committee that the Company's consolidated financial
statements were prepared in accordance with generally accepted accounting
principles, and the independent accountants represented that its presentations
to the Audit Committee included the matters required to be discussed with the
independent accountants by Statement on Auditing Standards No. 61,
"Communication with Audit Committees," as amended by Statement on Auditing
Standards No. 90, "Audit Committee Communications."

      The Company's independent accountants also provided the Audit Committee
with the written disclosures required by Independence Standards Board Standard
No. 1, "Independence Discussions with Audit Committees," and the Audit Committee
discussed with the independent accountants that firm's independence.

      Following the Audit Committee's discussions with management and the
independent accountants, the Audit Committee recommended that the Board of
Directors include the audited consolidated financial statements in the Company's
annual report on Form 10-K for the year ended December 31, 2001.

      Audit Committee:

            Marion C. Bauman (Chairman)              John C. Hugon
            C. L. Craig, Jr.                         Paul B. Odom, Jr.

                                  ANNUAL REPORT

      The Company's Annual Report to Stockholders for the year ended December
31, 2001 accompanies this Proxy Statement. No parts of the Annual Report are
incorporated by reference into this Proxy Statement and the Annual Report is not
deemed to be a part of the proxy soliciting material.

      The Company's annual report on Form 10-K for the year ended December 31,
2001 (other than the exhibits thereto) is available upon written request without
charge. Such requests should be directed to: Randy Foraker, Senior Vice
President and Controller, BancFirst Corporation, 101 North Broadway, Oklahoma
City, Oklahoma 73102.

                            PROPOSALS OF STOCKHOLDERS

      Proposals of stockholders intended to be presented at the next Annual
Meeting of Stockholders will be considered by the Board of Directors if the
written proposal, complying with the requirements established by the Commission,
is received at the Company's principal executive offices at 101 North Broadway,
