Dear Shareholder:

We are pleased to provide the annual report for the Smith Barney Arizona
Municipals Fund Inc. ("Fund") for the year ended May 31, 2000. A detailed
summary of the Fund's performance and investment strategy can be found in the
appropriate sections below.1 We hope that you find this report to be useful and
informative.

Performance Update

For the year ended May 31, 2000, the Fund's Class A shares, with and without
sales charges, reported total negative returns of 6.54% and 2.64%, respectively.
In comparison, the Lipper, Inc. peer group of Arizona tax-exempt funds returned
a negative 2.96% for the same period. (Lipper, Inc. is an independent mutual
fund-tracking organization.) For additional Fund performance information, please
refer to pages 5 through 7. (Past performance is not indicative of future
results).

Market and Economic Review

On May 16,2000,the Federal Reserve Board ("Fed") enacted the sixth in a series
of interest rate hikes that began June 30, 1999, when the federal funds rate was
at 4.75%. (The federal funds rate is the interest rate charged by banks with
excess reserves at a Federal Reserve district bank to banks needing overnight
loans to meet reserve requirements.) With the federal funds rate presently at
6.50%, the cumulative effect of the interest rate increases so far, in our view,
may begin to have a more pronounced effect in reducing inflationary pressures.

In our opinion, changes in the Fed's monetary policy generally take time to be
absorbed into the economy. We believe that the recent market rallies are a
result of monetary changes enacted six to nine months ago. In addition, barring
a major change in the economy or the rate of inflation, we think it is likely
that the Fed's monetary policy may be relatively benign for the remainder of
2000.

Over the past several weeks, the performance of the bond market has shown signs
of improvement amid a series of economic reports that suggest the economy is
slowing and that the Fed may be close to completing its series of interest rate
hikes. However, we also think that any further Fed policy actions may have
already been comfortably priced into the bond market.

The inversion of the yield curve, while making us somewhat cautious, still
indicates to us that the market believes inflation is under control. (The yield
curve is the graphical depiction of the relationship between the yield on bonds
of the same credit quality but different maturities. An inverted yield curve
represents a unique situation whereby short-term interest rates are higher than
long-term rates.) While the fundamentals in higher-quality tier securities are
still sound and valuations have improved, poor technical conditions, most
notably large pent-up issuance needs, may have created concern among many
investors about the future prospects for municipal bonds. Yet, as we discuss
later in the report, we are optimistic about current municipal bond
opportunities.

The prospect of further Fed tightening may result in modest further increases in
interest rates on securities with shorter maturities. In contrast, long-term
rates are not likely to rise much. Our favorable outlook for inflation, plus the
ongoing reduction in the supply of U.S. Treasuries, may help to contain the rise
in long-term rates and further invert the Treasury yield curve (that is,
long-term yields should fall even further below short-term yields).

In our view, modestly higher U.S. Treasury yields and a further increase in the
inversion of the yield curve are likely as the Fed continues to push up
short-term rates. A decrease in the amount of new issuance and more buy backs of
currently outstanding debt, while already largely discounted by the market, may
likely reinforce the inversion of the yield curve. In addition, we are presently
seeing general positive market sentiment toward bonds of higher credit quality.
We think that the short-end of the curve is racing to stay ahead of short-term
rates. The inversion is not just a factor of the U.S. Treasury buy back program,
but rather, it indicates that inflation may be under control and rates on
longer-term paper still represent fair value.

Arizona Economic Highlights2

Arizona's economy has grown over the last eight years, as the state continues to
implement business-friendly practices, leading to its top-five ranking in the
nation in terms of fastest job growth. The majority of new jobs throughout
Arizona have been primarily created by smaller businesses. Over the last year,
nearly 40,000 businesses were established in the Grand Canyon State, and Arizona
presently has the highest percentage of women-owned businesses in the U.S. at
41%.

Another factor behind the growth of the state's economy was a general reduction
in taxes. Over the last nine years, the Arizona's legislature has enacted $1.5
billion in tax cuts. Additionally, Arizona continues to score high marks in the
New Economy, one marked by a shift to innovation and technology as opposed to
mass production manufacturing. High technology companies have expanded their
presence in the U.S. economy, especially in the state, which may have helped to
further diversify Arizona's economy.

Investment Strategy

The Fund seeks to provide Arizona investors with the maximum amount of income
exempt from federal and Arizona state income taxes as is consistent with the
preservation of capital3. The Fund invests primarily in investment grade4
municipal securities.

Over the period covered by this report, the Fund continued to focus on
high-quality issues and remained broadly diversified across various sectors. As
of May 31, 2000, 87.8% of the Fund's holdings were rated investment grade. In
addition, 49.4% of the Fund's portfolio was invested in AAA-rated bonds, the
highest possible rating. At the end of the reporting period, the Fund's average
weighted maturity5 was roughly 18.7 years. As of May 31, 2000, the Fund's
largest holdings are concentrated in general obligation bonds (25.2%), hospital
bonds (17.9%) and multi-family housing bonds (14.6%).

The Fund's investment strategy going forward may be three-fold:

     .   We seek to lengthen maturities in the portfolio to take advantage of
         the inexpensive valuations of municipal bonds relative to U.S.
         Treasuries;
     .   We seek to focus on investing in high-grade issues; and
     .   We seek to invest in discount paper, an area where we believe we can
         obtain the best value.

Our aim is to sell off some of our shorter-term maturities that were defensive
and stretch at the longer end of the yield curve to lock in today's higher
rates. We see the best opportunity for potential reward right now at the long
end of the yield curve.

     Investors Service, Inc. or AAA,AA,A and BBB by Standard & Poor's Ratings
     Service, or have an equivalent rating by any nationally recognized
     statistical ratings organization, or are determined by the manager to be of
     equivalent quality.
5    Average maturity is the average timeframe within the portfolio for which
     the debt instruments are due and payable.

Municipal Bond Market Outlook
In our judgment, a number of influences remain favorable for the municipal bond
market. The new-issue municipals may be expected to decline this year, boosting
demand for bonds that are currently outstanding and enhancing interest for new
municipal securities expected in 2000.

National fiscal trends may be another major positive. During past economic
downturns, some municipal issuers faced declining tax receipts and were
hard-pressed to repay their bond obligations. Today, many state and local
governments have budget surpluses. We believe these surpluses may make investors
more comfortable holding municipals, even in a downturn. Lastly, recent
narrowing of spreads in the taxable market has made other fixed income
alternatives less attractive on a relative basis. All of these trends help to
explain why we remain optimistic about the long-term prospects for the municipal
bond market.

In closing, thank you for investing in the Smith Barney Arizona Municipals Fund
Inc. We look forward to continuing to help you pursue your financial goals in
the new century.

Sincerely,



/s/ Heath B. McLendon                /s/ Joseph P. Deane

(1)  Assumes reinvestment of all dividends and capital gain distributions, if
     any, at net asset value and does not reflect the deduction of the
     applicable sales charges with respect to Class A and L shares or the
     applicable contingent deferred sales charges ("CDSC") with respect to Class
     B and L shares.
(2)  Assumes reinvestment of all dividends and capital gains distributions, if
     any, at net asset value. In addition, Class A and L shares reflect the
     deduction of the maximum initial sales charges of 4.00% and 1.00%,
     respectively. Class B shares reflect the deduction of a 4.50% CDSC, which
     applies if shares are redeemed within one year from purchase. This CDSC
     declines by 0.50% the first year after purchase and thereafter by 1.00% per
     year until no CDSC is incurred. Class L shares also reflect the deduction
     of a 1.00% CDSC, which applies if shares are redeemed within one year from
     purchase.
+    Total return is not annualized, as it may not be representative of the
     total return for the year.
*    Inception dates for Class A, B and L shares are June 1, 1987, November 6,
     1992 and December 8, 1994, respectively.

+    Hypothetical illustration of $10,000 invested in Class A shares on May 31,
     1990, assuming deduction of the maximum 4.00% sales charge at the time of
     investment and reinvestment of dividends and capital gains, if any, at net
     asset value through May 31, 2000. The Lehman Brothers Municipal Bond Index
     is a broad based, total return index comprised of investment grade, fixed
     rate municipal bonds selected from issues larger than $50 million issued
     since January 1991. The Lipper Arizona Municipal Fund Average is composed
     of the Fund's peer group of mutual funds (40 funds as of May 31, 2000). The
     Index is unmanaged and is not subject to the same management and trading
     expenses as a mutual fund. The performance of the Fund's other classes may
     be greater or less than the Class A shares' performance indicated on this
     chart, depending on whether greater or lesser sales charges and fees were
     incurred by shareholders investing in the other classes.

     All figures represent past performance and are not a guarantee of future
     results. Investment returns and principal value will fluctuate, and
     redemption values may be more or less than the original cost. No adjustment
     has been made for shareholder tax liability on dividends or capital gains.

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
"B" 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. 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 differs from the highest rated issue only in a small
          degree.
A      -- Bonds rated "A" have a strong capacity to pay interest and repay
          principal although it is 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 debt in this category than in higher
          rated categories.
BB     -- Bonds rated "BB" have less near-term vulnerability to default than
          other speculative issues. However, they face major ongoing
          uncertainties or exposure to adverse business, financial, or economic
          conditions which could lead to inadequate capacity to meet timely
          interest and principal payments.
B      -- Bonds rated "B" have a greater vulnerability to default but currently
          have the capacity to meet interest payments and principal payments.
          Adverse business, financial, or economic conditions will likely impair
          capacity or willingness to pay interest and repay principal. The "B"
          rating category is also used for debt subordinated to senior debt that
          is assigned an actual or implied "BB" or "BB-" rating.

Moody's Investors Service, Inc. ("Moody's") -- Numerical modifiers 1, 2 and 3
may be applied to each generic rating from "Aa" to "Baa," 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 as 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 postion characterizes in this class.

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

1. Significant Accounting Policies

Smith Barney Arizona Municipals Fund Inc. ("Fund"), a Maryland corporation, is
registered under the Investment Company Act of 1940, as amended, as a
diversified, open-end management investment company.

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 quoted bid and ask prices provided by an independent
pricing service; (c) securities maturing within 60 days are valued at cost plus
accreted discount or minus amortized premium, which approximates value; (d)
gains or losses on the sale of securities are calculated by using the specific
identification method; (e) interest income,adjusted for amortization of premium
and accretion of original issue discount, is recorded on an accrual basis;
market discount is recognized upon the disposition of the security; (f)

Capital gains distributions, if any, are taxable to shareholders, and are
declared and paid at least annually.

4. Investment Advisory Agreement, Administration Agreement and Affiliated
   Transactions

SSB Citi Fund Management LLC ("SSBC"), formerly known as SSBC Fund Management
Inc., a subsidiary of Salomon Smith Barney Holdings Inc. ("SSBH"), which, in
turn, is a subsidiary of Citigroup Inc. ("Citigroup"), acts as investment
adviser to the Fund. The Fund pays SSBC an investment advisory fee calculated at
an annual rate of 0.30% of average daily net assets. This fee is calculated
daily and paid monthly.

SSBC also acts as the Fund's administrator for which the Fund pays a fee
calculated at an annual rate of 0.20% of the average daily net assets up to $500
million and 0.18% of the average daily net assets in excess of $500 million.
This fee is calculated daily and paid monthly.

Trust Company, another subsidiary of Citigroup, acts as the Fund's transfer
agent and PFPC Global Fund Services ("PFPC") acts as the Fund's sub-transfer
agent. CFTC receives account fees and asset-based fees that vary according to
the size and type of account. PFPC is responsible for shareholder recordkeeping
and financial processing for all shareholder accounts and is paid by CFTC.
During the period from October 1, 1999 through May 31, 2000, the Fund paid
transfer agent fees of $9,074 to CFTC.

CFBDS, Inc. ("CFBDS") acts as the Fund's distributor. Salomon Smith Barney Inc.
("SSB"), another subsidiary of SSBH, as well as certain other broker-dealers,
continues to sell Fund shares to the public as a member of the selling group.

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
initial purchase. This CDSC declines by 0.50% the first year after purchase 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 the first year of
purchase.

At May 31, 2000, the Fund had, for Federal income tax purposes, approximately

be distributed.

Independent Auditors' Report

The Board of Directors and Shareholders
Smith Barney Arizona Municipals Fund Inc.

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Smith Barney Arizona Municipals Fund Inc. as of
May 31, 2000, the related statement of operations for the year then ended, the
statements of changes in net assets for each of the years in the two-year period
then ended and financial highlights for each of the years in the five-year
period then ended. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of May 31, 2000, by correspondence with the custodian. As to
securities sold but not yet delivered, we performed other appropriate auditing
procedures. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of Smith
Barney Arizona Municipals Fund Inc. as of May 31, 2000, the results of its
operations for the year then ended, the changes in its net assets for each of
the years in the two-year period then ended and financial highlights for each of
the years in the five-year period then ended, in conformity with accounting
principles generally accepted in the United States of America.
