Smith Barney Arizona Municipals Fund Inc.
=========================================

Dear Shareholder:

We are pleased to provide the semi-annual report for the Smith Barney Arizona
Municipals Fund Inc. ("Fund") for the period ended November 30, 1997. In this
report, we summarize the period's prevailing economic and market conditions and
outline our portfolio strategy. A detailed summary of the Fund's performance can
be found in the appropriate sections that follow.

Performance Update

For the six months ended November 30, 1997, the Class A shares of the Fund
posted a total return of 5.17%. In comparison, the average for Arizona
tax-exempt funds was 5.03% for the same period according to Lipper Analytical
Services, Inc. ("Lipper"). (Lipper is a major independent fund-tracking
organization.) For performance information on the Fund's other share classes,
please turn to page four.

During the six months covered by this report, the Fund distributed income
dividends totaling $0.27 and a capital gain distribution of $0.05 for Class A
shares. Based on the net asset value ("NAV") of $10.42 as of November 30, 1997
and current monthly income dividend rate of $0.0445 for Class A shares, this
equates to an annualized distribution rate of 5.12%. For an Arizona state
resident in the combined federal and state tax bracket of 41.06%, the tax-free
yield of 5.12% is equivalent to a taxable yield of 8.69%. (This figure assumes
an investor is in the 31% federal income tax bracket.)

Market and Economic Overview

Municipal bonds generally performed well during the reporting period, benefiting
from a combination of a strong U.S. economy and low inflation. On the political
front, Congress passed the Taxpayer Reform Act of 1997, which provided targeted
tax relief and attempted to encourage more individual savings. But, in our view,
the most significant development for both stock and bond investors alike was
Asia's financial crisis in the fall of 1997.

For most of the reporting period, bond investors remained focused on how the
Federal Reserve Board ("Fed") would respond to a strengthening U.S. economy.
Yields on the 30-year U.S. Treasury bond, a key measure of interest rates, were
confined to a fairly narrow trading range as investors attempted to reconcile
the apparent contradiction between strong economic growth and low inflation.
Despite the lowest unemployment rate in more than twenty years, signs of
inflationary pressures were nearly absent and the bond market rallied sending
interest rates lower. Nevertheless, the Fed maintained its vigilance 


                                                                               1

against inflation and although it chose to ultimately remain on the sidelines,
it did indicate a bias toward tightening monetary policy at each of its meetings
in May, July, August and September.

In October, financial markets around the world were transformed almost overnight
as Asia's financial crisis, which had been developing since the summer, deepened
and eventually led to the sudden collapse of stock and bond markets throughout
the region. The dramatic decline of Asian financial markets caught many
investors by surprise and sentiment began to shift away from stocks in favor of
bonds as investors sought out "safe" havens. In the weeks that followed, the
U.S. Treasury bond market became one of the preferred alternatives for investors
seeking shelter from the "Asian contagion." The resulting rally in the
government bond market, along with an unusually heavy bond issuance, caused
municipal bonds to underperform U.S. Treasurys in November.

Arizona Economic Highlights

Arizona continues to enjoy phenomenal economic growth for the third year in a
row. Arizona's economic strength has been matched with even greater population
growth. Over the past century, Arizona has consistently ranked among the top
five fastest growing states for every decade except for two. This remarkable
expansion has boosted tax revenues, created budget surpluses and helped to lower
income taxes. However, the Valley of the Sun has experienced some growing pains
as it struggles to keep pace with the surging infrastructural demand for more
highways and schools.

The problem of shortage of classroom space has been compounded by a recent
federal court ruling mandating Arizona to divide resources more equitably among
school districts. As a result, we believe that the state may be forced to expand
municipal debt to fund not only the increased education needs, but for other
vital infrastructure projects as well.

Arizona municipal bonds tend to be of shorter maturity (usually between one to
ten years) than other states and therefore usually offer lower yields as well.
But because of our extensive municipal bond research capabilities and
underwriting strength, we have generally been able to identify and buy bonds
with yields that often exceed the typical Arizona municipal issue.

Fund's Investment Strategy

The Fund seeks to provide Arizona investors with as high a level of current
income exempt from federal and Arizona state income taxes as is consistent with
prudent investment management and preservation of capital. The Fund invests
primarily in investment-grade 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 November 30, 1997, approximately 89% of the Fund's holdings were rated

investment grade. (Investment-grade bonds are those rated Aaa, Aa, A and Baa by
Moody's 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 rating organization, or determined by the manager to be of
equivalent quality.) In addition, 52.3% of the Fund's portfolio was invested in
AAA-rated bonds, the highest rating. At the end of the reporting period, the
Fund's average weighted maturity was roughly 19 years.

As of November 30, 1997, the Fund's largest holdings are concentrated in
industrial development bonds (18.4%), general obligation bonds (18.1%) and
housing bonds (12.3%). Going forward, we expect to place even more emphasis on
housing bonds and hospital bonds (which represented nearly 9.2% of the Fund's
holdings as of November 30, 1997). We continue to favor housing bonds because,
in our opinion, they offer greater yield potential without significant added
risk. Moreover, we believe that ongoing reform among many hospitals has improved
their efficiency and bottom lines, making select hospital bonds even more
attractive investment opportunities.

Municipal Bond Market Outlook

We remain positive on the prospects for municipal bonds in the coming months.
Although the final impact of Asia's financial crisis on U.S. markets is not yet
clear, we believe that the excess production capacity that now exists in Asia
should help to offset rising prices in the U.S. However, the U.S. bond market
could experience some short-term selling pressure should the Japanese, the
largest foreign holder of U.S. government bonds, decide to sell their U.S. debt
holdings in order to restructure their still shaky financial industry.

Municipal bond issuance in 1997 was the second largest and the market's ability
to absorb these securities is an indication of healthy investor appetite for
tax-free investments. Insurance companies were among the largest buyers of these
bonds, but we believe that more and more individual investors are beginning to
recognize the attractive investment opportunities that exist in tax-free
municipal bonds.

In closing, thank you for your investment in the Smith Barney Arizona Municipals
Fund Inc. We look forward to helping you pursue your investment goals.

Sincerely,


/s/ Heath B. McLendon                          /s/ Lawrence T. McDermott

(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 shares or the applicable
     contingent deferred sales charges ("CDSC") with respect to Class B and C
     shares.

(2)  Assumes reinvestment of all dividends and capital gains distributions, if
     any, at net asset value. In addition, Class A shares reflect the deduction
     of the maximum initial sales charge of 4.00% and Class B shares reflect the
     deduction of a 4.50% CDSC, which applies if shares are redeemed 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 C shares reflect the deduction of a 1.00% CDSC, which applies if
     shares are redeemed within one year from initial 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 C shares are June 1, 1987, November 6,
     1992 and December 8, 1994, respectively.

+    Hypothetical illustration of $10,000 invested in Class A shares on November
     30, 1987, 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 November 30, 1997. 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 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
================================================================================

All ratings are by Standard & Poor's Ratings Service ("Standard & Poor's"),
except those identified by an asterisk (*) are rated by Moody's Investors
Service, Inc. ("Moody's"). The definitions of the applicable rating symbols are
set forth below:

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 -- 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 that are 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 that are 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 that are 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 that are 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.

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


                                                                              13

Short-Term Security Ratings
================================================================================

SP-1   --     Standard & Poor's highest rating indicating very 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.

     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
non-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)
dividends and distributions to shareholders are recorded on the ex-dividend
date; (g) direct expenses are charged to each class; management fees and general
fund expenses are allocated on the basis of relative net assets; (h) 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 (i) 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. Fund Concentration

     Since the Fund invests primarily in obligations of issuers within Arizona,
it is subject to possible concentration risks associated with economic,
political or legal developments or industrial or regional matters specifically
affecting Arizona.

     3. 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.

     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

     Mutual Management Corp. ("MMC"), formerly known as Smith Barney Mutual
Funds Management Inc., a subsidiary of Salomon Smith Barney Holdings Inc.
("SSBH"), acts as investment adviser to the Fund. The Fund pays MMC 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.

     MMC 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.

     Smith Barney Inc. ("SB"), another subsidiary of SSBH, acts as distributor
of the Fund's shares. For the six months ended November 30, 1997, SB received
sales charges of approximately $38,000 on sales of the Fund's Class A shares.

     There is a contingent deferred sales charge ("CDSC") of 4.50% on Class B
shares 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 C shares have a 1.00% CDSC if redemption occurs
within one year from initial purchase. For the six months ended November 30,
1997, CDSCs paid to SB for Class B shares were approximately $28,000.

     Pursuant to a Distribution Plan, the Fund pays a service fee with respect
to its Class A, B and C shares calculated at an annual rate of 0.15% of the
average daily net assets for each class. In addition, the Fund pays a
distribution fee with respect to its Class B and C shares calculated at an
annual rate of 0.50% and 0.55%, respectively, of the average daily net assets
for each class. For the six months ended November 30, 1997, total Distribution
Plan fees were:

     5. Investments

     During the six months ended November 30, 1997, the aggregate cost of
purchases and proceeds from sales of investments (including maturities, but
excluding short-term securities) were as follows:

<TABLE>
================================================================================
<S>                                                                  <C>        
Purchases                                                            $12,349,386

================================================================================
</TABLE>

     At November 30, 1997, the aggregate gross unrealized appreciation and
depreciation of investments for Federal income tax purposes were substantially
as follows:

<S>                                                                  <C>       
Gross unrealized appreciation                                        $3,201,803

===============================================================================
</TABLE>

     6. Capital Loss Carryforward

     At May 31, 1997, the Fund had, for Federal income tax purposes,
approximately $46,000 of capital loss carryforwards available to offset future
capital gains expiring May 31, 2004. To the extent that these carryforward
losses are used to offset capital gains, it is probable that the gains so offset
will not be distributed.

     7. Capital Shares

     At November 30, 1997, the Fund had 500 million shares of capital stock
authorized with par value of $0.001 per share. The Fund has the ability to issue
multiple classes of shares. Each share of a class represents an identical
interest and has the same rights, except that each class bears certain direct
expenses, specifically related to the distribution of its shares.

     At November 30, 1997, total paid-in capital amounted to the following for
each class:
