                         ANNUAL MEETING OF STOCKHOLDERS
                                FEBRUARY 24, 2003

                              --------------------

                                 PROXY STATEMENT

      This Proxy Statement is furnished in connection with the solicitation of
proxies by the Board of Directors (the "Board") of Municipal High Income Fund
Inc. (the "Fund") for use at the Annual Meeting of Shareholders (the "Meeting")
of the Fund to be held at 9:30 a.m. on February 24, 2003 at Citigroup Center,
153 East 53rd Street, 14th Floor Conference Center, New York, New York and at
any adjournments thereof. A Notice of Meeting of Shareholders (the "Notice") and
a proxy card accompany this Proxy Statement.

      The cost of soliciting proxies and the expenses incurred in preparing this
proxy statement will be borne by the Fund. Solicitation costs are expected to be
approximately $18,000. In addition, the Fund will reimburse brokerage firms or
other record holders for their expenses in forwarding solicitation materials to
beneficial owners of shares of the Fund. Proxy solicitations will be made
primarily by mail, but proxy solicitations also may be made by telephone or
personal interview conducted by officers of the Fund and officers and regular
employees of Smith Barney Fund Management LLC ("SBFM" or the "Manager"), the
Fund's investment adviser and administrator, Salomon Smith Barney Inc. ("Salomon
Smith Barney") and PFPC Global Fund Services, the Fund's transfer agent. The
cost of solicitations and the expense incurred in connection with preparing the
Proxy Statement and its enclosures will be paid by the Fund. The Fund will also
reimburse brokerage firms and others for their expenses in forwarding
solicitation materials to the beneficial owners of shares.

      The Annual Report of the Fund, including audited financial statements for
the fiscal year ended October 31, 2002, has previously been furnished to all
shareholders. This Proxy Statement is first being mailed to shareholders on or
about January 30, 2003. The Fund will provide additional copies of the annual
report to any shareholder upon request by calling the Fund at 1-800-331-1710.

      If the enclosed Proxy is properly executed and returned in time to be
voted at the Meeting, the shares of capital stock of the Fund ("Shares")
represented thereby will be voted in accordance with the instructions marked
thereon. Unless instructions to the contrary are marked thereon, a proxy will be
voted FOR the matter listed in the accompanying Notice of Annual Meeting of
Shareholders. For purposes of determining the presence of a quorum for
transacting business at the Meeting, abstentions and



broker "non-votes" (that is, proxies from brokers or nominees indicating that
such persons have not received instructions from the beneficial owner or other
persons entitled to vote shares on a particular matter with respect to which the
brokers or nominees do not have discretionary power) will be treated as shares
that are present but which have not been voted. Approval of Proposal 1 requires
the affirmative vote of a plurality of the votes cast at the Meeting with a
quorum present. Because the Proposal requires a proportion of votes cast for its
approval, abstensions and broker non-votes may influence whether a quorum is
present, but will have no impact on the requisite approval of such Proposal. Any
shareholder who has given a proxy has the right to revoke it at any time prior
to its exercise either by attending the Meeting and voting his or her shares in
person or by submitting a letter of revocation or a later-dated proxy to the
Fund at the above address prior to the date of the Meeting.

      In the event that a quorum is not present at the Meeting, or in the event
that a quorum is present but sufficient votes to approve the proposal are not
received, the persons named as proxies may propose one or more adjournments of
the Meeting to permit further solicitations of proxies. In determining whether
to adjourn the Meeting, the following factors may be considered: the nature of
the proposal that is the subject of the Meeting; the percentage of votes
actually cast; the percentage of negative votes actually cast; the nature of any
further solicitation and the information to be provided to shareholders with
respect to the reasons for the solicitation. Any adjournment will require the
affirmative vote of a majority of the Shares represented at the Meeting in
person or by proxy. A shareholder vote may be taken on the proposal in this
Proxy Statement prior to such adjournment if sufficient votes have been received
and it is otherwise appropriate. Under the Fund's By-laws, a quorum is
constituted by the presence in person or by proxy of the holders of a majority
of the outstanding Shares entitled to vote at the Meeting.

      The close of business on January 14, 2003 has been fixed as the record
date (the "Record Date") for the determination of shareholders entitled to
notice of and to vote at the Meeting and all adjournments thereof.

      The Fund has one class of common stock which has a par value of $.001 per
Share. As of the Record Date, there were 20,883,099.515 Shares outstanding. Each
shareholder is entitled to one vote for each Share held and a proportionate
fraction of a vote for any fractional Share held.

      As of the Record Date, to the knowledge of the Fund and the Board, no
single shareholder or "group" (as that term is used in Section 13(d) of the
Securities and Exchange Act of 1934 (the "Exchange Act")) beneficially owned
more than 5% of the outstanding Shares of the Fund. As of the Record Date, Cede
& Co., as nominee of The Depository Trust Company, was the record holder of
19,004,022 Shares, or 91.0% of the Fund's outstanding Shares. As of the Record
Date, the officers and Board Members of the Fund as a group beneficially owned
less than 1% of the outstanding Shares of the Fund.


                                       2


      In order that a shareholder's Shares may be represented at the Meeting,
shareholders are required to allow sufficient time for their proxies to be
received on or before 9:30 a.m. on February 24, 2003.

      As of the Record Date, to the knowledge of the Fund, no shares of
securities issued by Salomon Smith Barney's ultimate parent corporation,
Citigroup Inc. ("Citigroup"), were held by Directors who are not "interested
persons" of the Fund as that term is used in the Investment Company Act of 1940,
as amended, the "1940 Act".

                                  PROPOSAL 1:
                TO ELECT THREE (3) CLASS I DIRECTORS OF THE FUND

      The Board of Directors of the Fund is divided into three classes. The
Directors serving in Class I have terms expiring at the Meeting; each Class I
Director currently serving on the Board has been nominated by the Board of
Directors for reelection at the Meeting to serve for a term of three years
(until the annual meeting in 2006) or until their successors have been duly
elected and qualified. Class II directors and Class III directors will continue
to serve until the 2004 annual meeting and 2005 annual meeting, respectively.
One director previously serving in Class II, Heath B. McLendon, resigned as
Chairman and Director of the Fund in order to serve as Chairman of the Equity
Research Policy Committee of Salomon Smith Barney Inc. Mr. R. Jay Gerken is
currently serving as a Director, having been nominated and elected by the Board
of Directors at a meeting held on May 23, 2002, in order to fill the vacancy
resulting from Mr. McLendon's resignation. Mr. Gerken has been nominated by the
Board of Directors to be elected at the Meeting to serve as a Class I director.

      Each nominee has consented to serve as a Director if elected at the
Meeting. If a designated nominee declines or otherwise becomes unavailable for
election, however, the proxy confers discretionary power on the persons named
therein to vote in favor of a substitute nominee or nominees.

      Certain information concerning the nominees is set forth below. For any
nominee or Director indicated as owning shares of the Fund, such ownership
constituted less than 1% of the outstanding shares of the Fund as of the Record
Date. All of the nominees are currently Directors of the Fund. Except as
indicated, each nominee or Director has held the office shown or other offices
in the same company for the last five years.

----------
* Mr. Gerken is an "interested person" as defined in the 1940 Act.

      The Fund has no compensation committee of the Board, or any committee
performing similar functions. The Fund has a nominating committee composed of
Directors who are not "interested persons" of the Fund within the meaning of the
1940 Act (the "Independent Directors"), which is charged with recommending
nominees for election as Directors of the Fund. The nominating committee will
accept nominations for the office of Director made by the stockholders in a
written request addressed to the Secretary of the Fund which includes
biographical data and sets forth the qualifications of the proposed nominee. The
Fund has an audit committee composed of the Independent Directors, which is
charged with recommending a firm of independent auditors to the Fund and
reviewing accounting matters with the auditors as set forth in the committee's
charter. The audit committee held two meetings during the Fund's most recent
fiscal year. The Fund has a pricing committee composed of the Independent
Directors which is charged with determining fair value prices for securities
when required. The pricing committee held no meetings during the Fund's last
fiscal year.

      During the Fund's last fiscal year, four regular meetings of the Board
were held. In the last fiscal year, each Director attended at least 75% of the
regular meetings of the Board and each of the Directors, other than Messrs.
Bloostein and Hutchinson, attended at least 75% of the audit committee meetings
held.

                                  COMPENSATION

      Only the Independent Directors receive remuneration from the Fund for
acting as a Director. Aggregate expenses (including reimbursement for travel and
out-of-pocket expenses) of $5,205 were paid to such Directors by the Fund during
the calendar year ended December 31, 2001. Fees for the Independent Directors
are currently set at $5,000 per annum plus $500 per in-person Board meeting and
$100 per telephone conference call. Officers of the Fund are compensated by
Salomon Smith Barney.

      The following table shows the compensation paid by the Fund to each person
who was a Director during the Fund's last fiscal year:

----------
* Designates a Director who is an "interested person" of the Fund as defined
under the 1940 Act.

      At the end of the calendar year in which they attain age 80, Fund
Directors are required to change to emeritus status. Directors Emeritus are
entitled to serve in emeritus status for a maximum of 10 years during which time
they are paid 50% of the annual retainer fee and meeting fees otherwise
applicable to Fund Directors, together with reasonable out-of-pocket expenses
for each meeting attended. During the Fund's last fiscal year, compensation paid
by the Fund to Directors Emeritus totalled $3,500.

             Section 16(a) Beneficial Ownership Reporting Compliance

      Section 16(a) of the Exchange Act requires the Fund's officers and
Directors, and any persons who beneficially own more than ten percent of the
Fund's outstanding shares, to file reports of ownership with the Securities and
Exchange Commission, the New York Stock Exchange, Inc. (the "NYSE") and the
Fund. Based solely upon its review of the copies of such forms received by it
and representations from certain such persons, the Fund believes that during its
fiscal year ended October 31, 2002, all filing requirements applicable to such
persons were complied with.

                          Report of the Audit Committee

      Pursuant to a meeting of the audit committee on December 19, 2002, the
audit committee reports that it: (i) reviewed and discussed the Fund's audited
financial statements with management; (ii) discussed with the independent
auditors the matters required to be discussed by Statement on Auditing Standards
No. 61; and (iii) received written confirmation from KPMG that it is independent
and disclosures regarding such independence as required by Independence
Standards Board Standard No. 1, and discussed with the auditors the auditors'
independence. Based on the review and discussions referred to in items (i)
through (iii) above, the audit committee recommended to the Board of Directors
that the audited financial statements be included in the Fund's annual report
for the Fund's fiscal year ended October 31, 2002. The membership of the audit
committee is comprised of the following Directors: Dwight B. Crane, Paolo M.
Cucchi, Allan J. Bloostein, Robert A. Frankel, Dr. Paul Hardin, William R.
Hutchinson and George M. Pavia.

      Audit Fees. Fees for the annual audit of the Fund's financial statements
by KPMG for the fiscal year ended October 31, 2002 were $32,000.

      Financial Information Systems Design and Implementation Fees. Neither the
Fund nor SBFM or other entities controlling, controlled by, or under common
control with SBFM that provides services to the Fund engaged KPMG to provide
advice to the Fund, SBFM and entities controlled by or under common control with
SBFM regarding financial information system design and implementation during the
fiscal year ended October 31, 2002.

      All Other Fees. The aggregate fees billed for all other non-audit
services, including fees for tax related services, rendered by KPMG to the Fund,
SBFM and entities controlled by or affiliated with SBFM that provide services to
the Fund for the fiscal year ended October 31, 2002 were $2,200. The audit
committee of the Fund has determined that provision of these non-audit services
is compatible with maintaining the independence of KPMG.

                       DEADLINE FOR SHAREHOLDER PROPOSALS

      Shareholder proposals intended to be presented at the 2004 Annual Meeting
of Shareholders of the Fund must be received by September 20, 2003 to be
included in the proxy statement and the form of proxy relating to that meeting,
as the Fund expects that the 2004 Annual Meeting will be held in February of
2004. The submission by a shareholder of a proposal for inclusion in the proxy
statement does not guarantee that it will be included. Shareholder proposals are
subject to certain regulations under the federal securities laws.

      The persons named as proxies for the 2004 Annual Meeting of Shareholders
will have discretionary authority to vote on any matter presented by a
shareholder for action at that meeting unless the Fund receives notice of the
matter by December 6, 2003, in which case these persons will not have
discretionary voting authority except as provided in the Securities and Exchange
Commission's rules governing shareholder proposals.

matters are properly brought before the Meeting, the persons named as proxies in
the accompanying form of proxy will vote thereon in accordance with their
judgment, to the extent permissible under applicable law.

January 30, 2003
