HEATH B.                   JOSEPH P. 
MCLENDON                   DEANE

Chairman                   Vice President and
                           Investment Officer

Dear Shareholder:

We are pleased to provide the semi-annual report for the Smith Barney Managed
Municipals Fund Inc. ("Fund") for the period ended August 31, 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 August 31, 1997, the Fund had a total return of 5.26%,
4.99% and 4.97% for its Class A, B and C shares, respectively. In comparison,
the Fund's Lipper Analytical Services, Inc. peer group average posted a total
return of 4.02% for the same period. (Lipper is an independent fund-tracking
organization.) Over the six-month period covered by this report, the Fund
distributed income dividends totaling $0.45 for Class A shares; based on its net
asset value (NAV) of $15.97 as of August 31, 1997 and the current monthly income
dividend of $0.074 for Class A shares, this equates to an annualized
distribution rate of 5.56%. For an individual in the federal income tax bracket
of 36%, the tax free yield of 5.56% is equivalent to a taxable yield of 8.69%.

Municipal Bond Market Update

The past year in the municipal bond market can be described in three phases. The
first phase was a meaningful rally that began late summer 1996 and culminated in
Federal Reserve Board ("Fed") Chairman Alan Greenspan's "irrational exuberance"
speech in early December. The second phase was a notable increase in rates
because of subsequent fears of a major Fed rate action. The final phase,
culminating in today's market, is one in which rates are back to the levels
present before the Fed chairman's speech. We've believed all along that today's
municipal bond prices are quite appropriate, given the low inflation that
continues to be evident.

Investment Strategy

The Fund seeks to maximize current interest income exempt from Federal income
taxes to the extent consistent with prudent investment management and
preservation of capital. The Fund seeks to achieve this objective by investing
in intermediate- and long-term municipal securities issued by state and
municipal governments and by public authorities. The Fund continues its
investment strategy of selecting coupons and maturities that should benefit the
most from a further decline in long-term interest rates. The Fund's average
weighted maturity is approximately 23 years. In addition, in every market
downturn we have sought out bonds with coupons that would benefit from further
drops in interest rates.

As of this report, the 30-year U.S. Treasury bond yield is approximately 6.7%,
and it could decline to 6% in the near future if inflation remains at today's
low levels. Given our expectation for a continued moderate U.S. economy, we
continue to emphasize longer-term, deeper-discount bonds with very high credit
quality.

As of August 31, 1997, approximately 94.3% of the Fund's holdings were rated
investment grade (BBB/Baa and higher) by either Standard & Poor's Corporation or
Moody's Investors Service Inc., with about 69.5% of the Fund invested in
AAA-rated bonds, the highest possible rating. (Standard & Poor's and Moody's are
two major credit-reporting

and bond-rating agencies.) The Fund's largest holdings are concentrated in
transportation bonds (22.3%), water and sewer bonds (16.2%), utility bonds
(12.9%) and hospital bonds (9.2%).

Municipal Bond Market Outlook

Going forward, we would expect a decline in long-term rates, probably sooner
rather than later. The inflation rate is still key for us, and until we begin to
see that deteriorate we will continue to maintain our positive outlook for
municipal bonds.

Municipal bonds have continued to be in tight supply, and there is little reason
to believe there is a major supply spike on the horizon. Municipals have
outperformed the taxable market in the past year and will likely continue to do
so in the near future. In our view, the municipal bond market at today's levels
is very competitively priced and should provide investors with attractive
after-tax yields. Furthermore, municipal bonds may have some capital
appreciation possibilities if the inflation numbers continue on today's steady
path.

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

Sincerely,                 Sincerely,

Now More Than Ever . . .
The Compelling Case for Municipal Bonds Continues!

o    Supply of municipal bonds may be tapering off while the demand from aging
     Baby Boomers entering their peak earning years for tax-free income is
     expected to rise.

o    The recent enactment of the Taxpayer Relief Act of 1997 has made taxes and
     the need for tax-exempt income more prominent in the minds of many
     investors and therefore may stimulate more demand for municipal bonds in
     the future.

================================================================================
 An Interview with Portfolio Manager Joe Deane
================================================================================

Joseph "Joe" P. Deane, Managing Director of Smith Barney, has more than 25 years
of Wall Street experience. Joe currently manages in excess of $5 billion of
Smith Barney assets in both open- and closed-end mutual funds, including the
Smith Barney Managed Municipals Fund. We recently talked with Joe about his
outlook for the municipal bond market in the coming months and how he manages
money.

Joe, you were named the top-rated fixed-income manager of 1996 by Morningstar,
Inc., a major fund-ranking organization. To what do you attribute this extremely
prestigious honor?

Joe: Consistency. We think we're pretty unique in the business, because we've
been able to produce consistent numbers through every type of market condition.
For example, we did well in 1992-1993 when the market was up. But we also
performed well in 1994 when the municipal bond market fell.

Joe, what are the dangers of municipal bond investors focusing on yield at the
expense of total return?

Joe: We believe you can't just manage for yield alone, and that's why we
concentrate so much on total return. By making adjustments to your fund's
average maturity you can try to lessen the impact of volatility or take
advantage of it. We think you're going to miss tremendous opportunities or make
yourself more vulnerable to losses when you do not manage for total return.

Moreover, our total-return emphasis is not just about making money, it's about
saving money in down markets. Over the long term, you need to generate high
total returns in order to provide your investors with a competitive stream of
income, especially when interest rates are heading down.

Joe, what is your outlook for the municipal bond market over the next twelve to
eighteen months?

Joe: While that may be too long a time frame to predict market conditions with
any degree of accuracy, we expect that the bond market will rally from today's
levels. We're extremely positive on the market over the next six months.

Joe, is there any risk to your positive outlook on the municipal bond market?

Joe: Because inflation is the main factor driving the bond markets, the greatest
risk to our expectations of a favorable market is a real short-term surprise
with respect to inflation. While we think the chances for higher inflation over
the short run are virtually non-existent, over the long term we will continue to
monitor the numbers closely for any signs of inflationary pressures.

What impact do the recent tax law changes have on the municipal bond market?

Joe: We don't think it will have much impact on the municipal bond market and it
certainly hasn't lowered the need for tax-exempt income. Yet a lower long-term
capital gains rate probably shifts the focus somewhat to discount bonds rather
than premium bonds because of the lower capital gains tax rate.

What differentiates you from many other portfolio managers?

Joe: We have a tendency to lean against the wind, based on a combination of
intuition and experience. And while nobody wants to be contrarian all of the
time, you need to be able to make a bid when you think the market has gotten
beaten down to inexpensive levels, or sell when you think the market is too
expensive. We think many market inefficiencies are caused by emotion, and we're
not afraid to make significant moves quickly if we believe they are appropriate.

Are municipal bond investors being sufficiently compensated in today's
marketplace when they move away from higher-quality issues toward riskier ones?

Joe: Not really. In fact, in all the years we've been managing money the spread
between AAA-rated issues and BBB-rated issues is now probably the lowest it's
been since I began my career in 1970. In our view, there is much more value in
the higher-rated issues. Right now, there is not enough extra yield associated
with lesser-rated bonds to justify the added risk, so we invest primarily in
high-quality issues.

Joe, how do you stay attuned to the needs of your shareholders?

Joe: If you hold the number of public seminars I do, you really can't lose sight
of the needs of your shareholders. In fact, meeting with individual investors on
a regular basis is one of the most important ways for a portfolio manager to
keep a healthy perspective on his or her job. In addition, constant interaction
with shareholders over the years is a humbling experience and drives home the
point that there are an awful lot of people out there counting on you to do a
good job with their hard-earned money.

And you wouldn't do anything differently with their assets that you would with
your own?

Joe: I would never do anything with their money that I wouldn't do with my own.
That's been one of my guiding principles since I started managing money in 1970.

Joe, what advice would you give an investor who wants to participate in a
municipal bond club?

Joe: I would suggest that most individual investors would be better off
investing in a professionally managed municipal bond fund. But, as previously
noted, the key to successful investing in municipal bonds is not to focus on
yield alone, but on total return potential as well. In addition, I would advise
that most individual investors stand to benefit from maintaining a long-term
perspective. In my opinion, successful investing is about time and not timing.

Joe, what additional resources do you have as a professional money manager that
the average investor might not have?

Joe: There's been an explosion in the amount of technology available to
professional money managers, which in turn has compressed the reaction time you
need to make an investment decision. And while many of these technological tools
are now accessible to the average investor, we have a distinct advantage in
being able to interpret the information and act more quickly.

Joe, thanks for spending some time with us today.

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

(2)  Assumes reinvestment of all dividends and capital gain 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 the first year of purchase.

*    Inception dates for Class A, B, C and Y shares are March 4, 1981, November

+    Hypothetical illustration of $10,000 invested in Class A shares on August
     31, 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 August 31, 1997. The Lehman Brothers Municipal Bond
     Fund Index is a weighted composite which is comprised of more than 15,000
     bonds issued within the last 5 years, having a minimum credit rating of at
     least Baa and a maturity of at least 2 years, excluding all bonds subject
     to the Alternative Minimum Tax and bonds with floating or zero coupons. The
     index is unmanaged and is not subject to the same management and trading
     expenses as a mutual fund. The Lipper Analytical Services, Inc. Peer Group
     Average ("Lipper Peer Group Average") is composed of an average of the
     Fund's peer group of 254 mutual funds investing in municipal securities as
     of August 31, 1997. 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

 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 -- Rating 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 bonds in this category than in higher
         rated categories.

BB    -- Bonds rated "BB" have less near-term vulnerability to default than
         other speculative issues. However, it faces 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. The "BB" rating category is also used for debt
         subordinated to senior debt that is assigned an actual or implied
         "BBB-" rating.

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"
         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 "B," 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.

Ba    -- Bonds that are 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 time over the future.
         Uncertainty of position characterizes bonds in this class.

B     -- Bonds that are 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.

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

 Short-Term Securities Ratings
================================================================================

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.
        
VMIG1    -- 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.

 Notes to Financial Statements (unaudited)

1.   Significant Accounting Policies

Smith Barney Managed 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 bid and ask prices provided by an independent pricing
service that are based on transactions in municipal obligations, quotations from
municipal bond dealers, market transactions in comparable securities and various
relationships between securities; (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
the 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; investment
advisory fees and general Fund expenses are allocated on the basis of relative
net assets of each class; (h) the character of income and gains to be
distributed are determined in accordance with income tax regulations which may
differ from generally accepted accounting principles. At February 28, 1997,
reclassifications were made to the Fund's capital accounts to reflect permanent
book/tax differences and income and gains available for distributions under
income tax regulations. Net investment income, net realized gains and net assets
were not affected by this change; (i) 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 (j) 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 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 requirements that allow interest from municipal
securities, which is exempt from regular Federal income tax and from certain
states' income taxes, to retain its exempt-interest status when distributed to
the shareholders of the Fund.

Capital gain distributions, if any, are taxable to shareholders, and are
declared and paid at least annually. If necessary, additional taxable
distributions may be made to avoid a Federal excise tax.

3.   Investment Advisory Agreement, Administration Agreement and Other
     Transactions

Smith Barney Mutual Funds Management Inc. ("SBMFM"), a subsidiary of Smith
Barney Holdings Inc. ("SBH"), acts as investment adviser to the Fund. The Fund
pays SBMFM an advisory fee calculated at an annual rate of 0.35% of the average
daily net assets up to $500 million; 0.32% of the average daily net assets of
the next $1.0 billion and 0.29% in excess of $1.5 billion. This fee is
calculated daily and paid monthly.

================================================================================

SBMFM 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; 0.18% of the average daily net assets of the next $1.0 billion and
0.16% of the average daily net assets in excess of $1.5 billion. This fee is
calculated daily and paid monthly.

Smith Barney Inc. ("SB"), another subsidiary of SBH, acts as distributor of Fund
shares. For the six months ended August 31, 1997, SB received approximately
$34,000 on sales of the Fund's Class A shares.

There is a contingent deferred sales charge ("CDSC") of 4.50% on Class B shares,
which applies if redemption occurs less than 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,
which applies if redemption occurs within the first year of purchase. For the
six months ended August 31, 1997, CDSCs paid to SB were approximately $30,000
for Class B shares.

Pursuant to a Distribution Plan, the Fund pays a service fee with respect to its
Class A, B and C shares, calculated at the annual rate of 0.15% of the average
daily net assets for each respective class. In addition, the Fund pays a
distribution fee with respect to its Class B and C shares calculated at the
annual rate of 0.50% and 0.55%, of the average daily net assets of each class,
respectively.

For the six months ended August 31, 1997, total Distribution Plan fees incurred
were:

</TABLE>                                           

5.   Futures Contracts

Initial margin deposits made upon entering into futures contracts are recognized
as assets. The initial margin is segregated by the custodian and is noted in the
schedule of investments. 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 made or received
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 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 (futures contracts) and the credit
risk should a counterparty fail to perform under such contracts.
