R. Jay Gerken, CFA
 R. JAY GERKEN, CFA

 Chairman, President and Chief Executive Officer

Dear Shareholder,

In an effort to jump-start a weak economy, the Federal Reserve reduced
short-term interest rates again in late June, driving the federal funds rate/1/
to just 1%, its lowest level since the Eisenhower Administration. During this
declining-rate environment, bond yields continued to drop. Meanwhile, many
states have been grappling with budget deficits brought on by the faltering
economy, layoffs and declining incomes -- all leading to lower tax revenues.
Shortly after the Fed eased rates in June, the fixed-income markets experienced
a sharp reversal over the summer as signs emerged that economic growth was more
robust than previously thought. Interest rates moved up sharply as a result. If
rates were to continue rising, that would lead to higher levels of income from
fixed-income securities. However, rising rates would also lead to declining
prices on outstanding bonds because prices move in the opposite direction of
interest rates.

In this environment, the fund performed as follows:
Smith Barney Muni Funds: National Portfolio's Performance

For the six months ended September 30, 2003, Class A shares of the fund,
without sales charges, returned 2.91%./2/ This compared with a return of 2.66%
of the broad based Lehman Brothers Municipal Bond Index and 2.57% of the fund's
Lipper peer group of general municipal debt funds, over the same period./3/

                             PERFORMANCE SNAPSHOT
                           AS OF SEPTEMBER 30, 2003
                         (not including sales charges)



                                                 6 Months
                                              
 Class A Shares                                    2.91%
 Lehman Brothers Municipal Bond Index              2.66%
 Average of Lipper general municipal debt funds    2.57%


  Class A share returns assume the reinvestment of income dividends and capital
  gains distributions at net asset value and the deduction of all fund
  expenses. Returns have not been adjusted to include sales charges that may
  apply when shares are purchased or the deduction of taxes that a shareholder
  would pay on fund distributions. All figures represent past performance and
  are not a guarantee of future results. Principal value and investment returns
  will fluctuate and investors' shares, when redeemed may be worth more or less
  than their original cost.

  The Lehman Brothers Municipal Bond Index is a broad measure of the municipal
  bond market with maturities of at least one year. Please note that an
  investor cannot invest directly in an index.

  Lipper is a major independent mutual-fund tracking organization. Returns are
  based on the six-month period ended September 30, 2003, calculated among 304
  funds in the Lipper general municipal debt funds category with reinvestment
  of dividends and capital gains excluding sales charges.

  Certain investors may be subject to the federal Alternative Minimum Tax and
  state and local taxes will apply. Capital gains, if any, are fully taxable.
  Please consult your personal tax adviser.


/1/The federal funds rate is the interest rate that banks with excess reserves
   at a Federal Reserve district bank charge other banks that need overnight
   loans.
/2/Performance for the fund's other share classes can be found in the Financial
  Highlights section in this report. Performance for the other share classes
  may vary.
/3/Lipper is a major independent mutual-fund tracking organization. Returns are
   based on the six-month period ended September 30, 2003, calculated among 304
   funds in the Lipper general municipal debt funds category with reinvestment
   of dividends and capital gains excluding sales charges.

At times of uncertainty such as these, it is more important than ever to
develop and stick with a long-range plan. In addition to their income-producing
capabilities, we believe that bonds can be an effective means of
diversification in an overall investment portfolio. And municipal securities
can provide income free from federal, and sometimes state and local, income
taxes. Certain investors may be subject to the federal Alternative Minimum Tax
and state and local income taxes will apply. Capital gains, if any, are fully
taxable. Consult your personal tax adviser for more details. Please work
closely with your financial adviser to determine your proper allocation to
fixed-income securities based on your risk/reward profile and to explore the
role they can play in achieving your long-term financial goals.

As always, thank you for your entrusting your assets to us. We look forward to
helping you continue to meet your financial goals.

Sincerely,

/s/ R. Jay Gerken

 BOND RATINGS (UNAUDITED)


The definitions of the applicable rating symbols are set forth below:

Standard & Poor's Ratings Service ("Standard & Poor's") -- Ratings from "AA" to
"CCC" may be modified by the addition of a plus (+) or minus (-) sign to show
relative standings within the major rating categories.

AAA          -- Bonds rated "AAA" have the highest rating assigned by Standard
                & Poor's to a debt obligation. Capacity to pay interest and
                repay principal is extremely strong.
AA           -- Bonds rated "AA" have a very strong capacity to pay interest
                and repay principal and differ from the highest rated issues
                only in a small degree.
A            -- Bonds rated "A" have a strong capacity to pay interest and
                repay principal although they are somewhat more susceptible to
                the adverse effects of changes in circumstances and economic
                conditions than debt in higher rated categories.
BBB          -- Bonds rated "BBB" are regarded as having an adequate capacity
                to pay interest and repay principal. Whereas they normally
                exhibit adequate protection parameters, adverse economic
                conditions or changing circumstances are more likely to lead to
                a weakened capacity to pay interest and repay principal for
                bonds in this category than for bonds in higher rated
                categories.
BB,          -- Bonds rated "BB", "B", "CCC" and "CC" are regarded, on balance,
B, CCC and CC   as predominantly speculative with respect to capacity to pay
                interest and repay principal in accordance with the terms of
                the obligation. "BB" represents a lowest degree of speculation
                than "B", "CCC" and "CC", the highest degree of speculation.
                While such bonds will likely have some quality and protective
                characteristics, these are outweighed by large uncertainties or
                major risk, exposures to adverse conditions.

Moody's Investors Service ("Moody's") -- Numerical modifiers 1, 2 and 3 may be
applied to each generic rating from "Aa" to "Caa," where 1 is the highest and 3
the lowest ranking within its generic category.

Aaa          -- Bonds rated "Aaa" are judged to be of the best quality. They
                carry the smallest degree of investment risk and are generally
                referred to as "gilt edge." Interest payments are protected by
                a large or by an exceptionally stable margin and principal is
                secure. While the various protective elements are likely to
                change, such changes as can be visualized are most unlikely to
                impair the fundamentally strong position of such issues.
Aa           -- Bonds rated "Aa" are judged to be of high quality by all
                standards. Together with the "Aaa" group they comprise what are
                generally known as high grade bonds. They are rated lower than
                the best bonds because margins of protection may not be as
                large in "Aaa" securities or fluctuation of protective elements
                may be of greater amplitude or there may be other elements
                present which make the long-term risks appear somewhat larger
                than in "Aaa" securities.
A            -- Bonds rated "A" possess many favorable investment attributes
                and are to be considered as upper medium grade obligations.
                Factors giving security to principal and interest are
                considered adequate but elements may be present which suggest a
                susceptibility to impairment some time in the future.
Baa          -- Bonds rated "Baa" are considered to be medium grade
                obligations, i.e., they are neither highly protected nor poorly
                secured. Interest payments and principal security appear
                adequate for the present but certain protective elements may be
                lacking or may be characteristically unreliable over any great
                length of time. Such bonds lack outstanding investment
                characteristics and in fact have speculative characteristics as
                well.
Ba           -- Bonds rated "Ba" are judged to have speculative elements; their
                future cannot be considered as well assured. Often the
                protection of interest and principal payments may be very
                moderate and thereby not well safeguarded during both good and
                bad times over the future. Uncertainty of position
                characterizes bonds in this class.
B            -- Bonds rated "B" generally lack characteristics of desirable
                investments. Assurance of interest and principal payments or of
                maintenance of other terms of the contract over any long period
                of time may be small.
Caa          -- Bonds rated "Caa" are of poor standing. These issues may be in
                default, or present elements of danger may exist with respect
                to principal or interest.

 BOND RATINGS (UNAUDITED) (CONTINUED)



Fitch Ratings ("Fitch") -- Ratings of "A" to "B" may be modified by the
addition of a plus (+) or minus (-) sign to show relative standings with the
major ratings categories.

A            -- Bonds rated "A" are considered to have a low expectation of
                credit risk. The capacity for timely payment of financial
                commitments is considered to be strong, but may be more
                vulnerable to changes in economic conditions and circumstances
                than bonds with higher ratings.
BBB          -- Bonds rated "BBB" currently have a low expectation of credit
                risk. The capacity for timely payment of financial commitments
                is considered to be adequate. Adverse changes in economic
                conditions and circumstances, however, are more likely to
                impair this capacity. This is the lowest investment-grade
                category assigned by Fitch.
BB           -- Bonds rated "BB" indicate that there is a possibility of credit
                risk developing, particularly as the result of adverse economic
                change over time; however, business of financial alternatives
                may be available to allow financial commitments to be met.
B            -- Bonds rated "B" indicate that significant credit risk is
                present, but a limited margin of safety remains. Financial
                Commitments are currently being met; however, capacity for
                continued payment is contingent upon a sustained, favorable
                business and economic environment.

NR           -- Indicates that the bond is not rated by Standard & Poor's,
                Moody's or Fitch.

 SHORT-TERM SECURITY RATINGS (UNAUDITED)

SP-1         -- Standard & Poor's highest rating indicating very strong or
                strong capacity to pay principal and interest; those issues
                determined to possess overwhelming safety characteristics are
                denoted with a plus (+) sign.
A-1          -- Standard & Poor's highest commercial paper and variable-rate
                demand obligation (VRDO) rating indicating that the degree of
                safety regarding timely payment is either overwhelming or very
                strong; those issues determined to possess overwhelming safety
                characteristics are denoted with a plus (+) sign.
VMIG 1       -- Moody's highest rating for issues having a demand feature --
                VRDO.
P-1          -- Moody's highest rating for commercial paper and for VRDO prior
                to the advent of the VMIG 1 rating.

             17 Smith Barney Muni Funds | 2003 Semi-Annual Report




 NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

1. Significant Accounting Policies

The National Portfolio ("Fund"), a separate investment fund of the Smith Barney
Muni Funds ("Trust"), a Massachusetts business trust, is registered under the
Investment Company Act of 1940, as amended, as a diversified open-end
management investment company. The Trust consists of this Fund and eight other
separate investment funds: Florida, Georgia, Limited Term, New York,
Pennsylvania, California Money Market, Massachusetts Money Market and New York
Money Market Portfolios. The financial statements and financial highlights for
the other funds are presented in separate shareholder reports.

The significant accounting policies consistently followed by the Fund are: (a)
security transactions are accounted for on trade date; (b) securities are
valued at the mean between the bid and asked prices provided by an independent
pricing service which are based on transactions in municipal obligations,
quotations from municipal bond dealers, market transactions in comparable
securities and various relationships between securities; (c) securities for
which market quotations are not available will be valued in good faith at fair
value by or under the direction of the Board of Trustees; (d) securities
maturing within 60 days are valued at cost plus accreted discount, or minus
amortized premium, which approximates value; (e) gains or losses on the sale of
securities are calculated by using the specific identification method; (f )
interest income, adjusted for amortization of premium and accretion of
discount, is recorded on an accrual basis; (g) dividends and distributions to
shareholders are recorded on the ex-dividend date; (h) class specific expenses
are charged to each class; management fees and general fund expenses are
allocated on the basis of relative net assets of each class or on another
reasonable basis; (i) the character of income and gains to be distributed is
determined in accordance with income tax regulations which may differ from
accounting principles generally accepted in the United States of America; ( j)
the Fund intends to comply with the applicable provisions of the Internal
Revenue Code of 1986, as amended, pertaining to regulated investment companies
and to make distributions of taxable income sufficient to relieve it from
substantially all Federal income and excise taxes; and (k) estimates and
assumptions are required to be made regarding assets, liabilities and changes
in net assets resulting from operations when financial statements are prepared.
Changes in the economic environment, financial markets and any other parameters
used in determining these estimates could cause actual results to differ.

2. Exempt-Interest Dividends and Other Distributions

The Fund intends to satisfy conditions that will enable interest from municipal
securities, which is exempt from regular Federal income tax and from designated
state income taxes, to retain such tax-exempt status when distributed to the
shareholders of the Fund.

It is the Fund's policy to distribute dividends monthly. Capital gains
distributions, if any, are taxable to shareholders, and are declared and paid
at least annually.

3. Management Agreement and Other Transactions

Smith Barney Fund Management LLC ("SBFM"), an indirect wholly-owned subsidiary
of Citigroup Inc. ("Citigroup"), acts as investment manager to the Fund. The
Fund pays SBFM a management fee calculated at the annual rate of 0.45% of the
Fund's average daily net assets. This fee is calculated daily and paid monthly.

Citicorp Trust Bank, fsb. ("CTB"), another subsidiary of Citigroup, acts as the
Fund's transfer agent. PFPC Inc. ("PFPC") acts as the Fund's sub-transfer
agent. CTB receives account fees and asset-based fees that vary according to

 NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)


There are maximum initial sales charges of 4.00% and 1.00% for Class A and L
shares, respectively. There is a contingent deferred sales charge ("CDSC") of
4.50% on Class B shares, which applies if redemption occurs within one year
from purchase payment. This CDSC declines by 0.50% the first year after
purchase payment and thereafter by 1.00% per year until no CDSC is incurred.
Class L shares also have a 1.00% CDSC, which applies if redemption occurs
within one year from purchase payment. In certain cases, Class A shares have a
1.00% CDSC, which applies if redemption occurs within one year from purchase
payment. This CDSC only applies to those purchases of Class A shares, which
when combined with current holdings of Class A shares, equal or exceed $500,000
in the aggregate. These purchases do not incur an initial sales charge.

For the six months ended September 30, 2003, Citigroup Global Markets Inc.
("CGM"), another indirect wholly-owned subsidiary of Citigroup, received sales
charges of approximately $120,000 and $24,000 on sales of the Fund's Class A
and L shares, respectively.

In addition, for the six months ended September 30, 2003, CDSCs paid to CGM
were approximately:

5. Futures Contracts

Securities or cash equal to the initial margin amount are either deposited with
the broker or segregated by the custodian upon entering into the futures
contract. Additional securities are also segregated up to the current market
value of the futures contract. During the period the futures contract is open,
changes in the value of the contract are recognized as unrealized gains or
losses by "marking-to-market" on a daily basis to reflect the market value of
the contract at the end of each day's trading. Variation margin payments are
received or made and recognized as assets due from or liabilities due to
broker, depending upon whether unrealized gains or losses are incurred. When
the contract is closed, the Fund records a realized gain or loss equal to the
difference between the proceeds from (or cost of ) the closing transactions and
the Fund's basis in the contract. The Fund enters into such contracts typically
to hedge a portion of its portfolio. The Fund bears the market risk that arises
from changes in the value of the financial instruments and securities indices.

9. Subsequent Event

The Fund has received the following information from Citigroup Asset Management
("CAM"), the Citigroup business unit which includes the Fund's Investment
Manager and other investment advisory companies, all of which are indirect,
wholly-owned subsidiaries of Citigroup. CAM is reviewing its entry, through an
affiliate, into the transfer agent business in the period 1997-1999. As CAM
currently understands the facts, at the time CAM decided to enter the transfer
agent business, CAM sub-contracted for a period of five years certain of the
transfer agency services to a third party and also concluded a revenue
guarantee agreement with this sub-contractor providing that the sub-contractor
would guarantee certain benefits to CAM or its affiliates (the "Revenue
Guarantee Agreement"). In connection with the subsequent purchase of the
sub-contractor's business by an affiliate of the current sub-transfer agent
(PFPC Inc.) used by CAM on many of the funds it manages, this Revenue Guarantee
Agreement was amended eliminating those benefits in exchange for arrangements
that included a one-time payment from the sub-contractor.

The Boards of CAM-managed funds (the "Boards") were not informed of the Revenue
Guarantee Agreement with the sub-contractor at the time the Boards considered
and approved the transfer agent arrangements. Nor were the Boards informed of
the subsequent amendment to the Revenue Guarantee Agreement when that occurred.

CAM has begun to take corrective actions. CAM will pay to the applicable funds
$16 million (plus interest) that CAM and its affiliates received from the
Revenue Guarantee Agreement and its amendment. CAM also plans an independent
review to verify that the transfer agency fees charged by CAM were fairly
priced as compared to competitive alternatives. CAM is instituting new
procedures and making changes designed to ensure no similar arrangements are
entered into in the future.

CAM has briefed the SEC, the New York State Attorney General and other
regulators with respect to this matter, as well as the U.S. Attorney who is
investigating the matter. CAM is cooperating with governmental authorities on
this matter, the ultimate outcome of which is not yet determinable.

(1) For the six months ended September 30, 2003 (unaudited).
(2) Per share amounts have been calculated using the monthly average shares
    method.
(3) On June 12, 1998, Class C shares were renamed as Class L shares.
(4) Effective April 1, 2001, the Fund adopted a change in the accounting method
    that requires the Fund to amortize premiums and accrete all discounts.
    Without the adoption of this change, for the year ended March 31, 2002, net
    investment income, net realized and unrealized loss and the ratio of net
    investment income to average net assets would have been $0.69, $0.40 and
    5.08%, respectively. Per share information, ratios and supplemental data
    for the periods prior to April 1, 2001 have not been restated to reflect
    this change in presentation.
* Amount represents less than $0.01 per share.
++ Total return is not annualized, as it may not be representative of the total
   return for the year.
