Annual Report

October 31, 1999


This report, including the financial information herein, is
transmitted to the shareholders of MuniYield Insured Fund, Inc. for
their information. It is not a prospectus, circular or
representation intended for use in the purchase of shares of the
Fund or any securities mentioned in the report. Past performance
results shown in this report should not be considered a
representation of future performance. The Fund has leveraged its
Common Stock by issuing Preferred Stock to provide the Common Stock
shareholders with a potentially higher rate of return. Leverage
creates risks for Common Stock shareholders, including the
likelihood of greater volatility of net asset value and market price
of shares of the Common Stock, and the risk that fluctuations in the
short-term dividend rates of the Preferred Stock may affect the
yield to Common Stock shareholders. Statements and other information
herein are as dated and are subject to change.

TO OUR SHAREHOLDERS


For the year ended October 31, 1999, the Common Stock of MuniYield
Insured Fund, Inc. earned $0.886 per share income dividends, which
included earned and unpaid dividends of $0.073. This represents a
net annualized yield of 6.50%, based on a month-end net asset value
of $13.64 per share. Over the same period, the total investment
return on the Fund's Common Stock was -8.42%, based on a change in
per share net asset value from $16.28 to $13.64, and assuming
reinvestment of $1.079 per share ordinary income dividends and
$0.263 per share capital gains distributions.

For the six-month period ended October 31, 1999, the total
investment return on the Fund's Common Stock was -9.12%, based on a
change in per share net asset value from $15.49 to $13.64, and
assuming reinvestment of $0.432 per share income dividends.

For the six-month period ended October 31, 1999, the Fund's Auction
Market Preferred Stock had an average yield of 3.56% for Series A,
3.62% for Series B, 3.56% for Series C, 3.45% for Series D, 3.28%
for Series E, 3.10% for Series F and 3.30% for Series G.


The Municipal Market Environment
The combination of steady strong domestic economic growth,
improvement in foreign economies (most notably in Japan) and
increasing investor concerns regarding potential increases in US
inflation put upward pressure on bond yields throughout the 12-month
period ended October 31, 1999. Continued strong US employment
growth, particularly the decline in the US unemployment rate to 4.2%
in early June, was among the reasons the Federal Reserve Board cited
for raising short-term interest rates in late June and again in late
August. US Treasury bond yields reacted by climbing above 6.375% by
late October. However, by October 31, 1999, economic indicators were
released suggesting that despite strong economic and employment
growth in the third fiscal quarter of 1999, inflationary pressures
have remained extremely well-contained. This resulted in a
significant rally in the US Treasury bond market, pushing US
Treasury bond yields downward to approximately 6.15% by October 31,
1999. During the last six months, yields on 30-year US Treasury
bonds increased more than 50 basis points (0.50%).

Long-term tax-exempt bond yields also rose during the six months
ended October 31, 1999. Until early May, the municipal bond market
was able to withstand much of the upward pressure on bond yields.
However, investor concerns of additional moves by the Federal
Reserve Board to moderate US economic growth and, more importantly,
the loss of the strong technical support that the tax-exempt market
enjoyed in early 1999 helped push municipal bond yields
significantly higher for the remainder of the period. The yields on
long-term tax-exempt revenue bonds rose almost 90 basis points to
6.18% by October 31, 1999, as measured by the Bond Buyer Revenue
Bond Index.

In recent months, the significant decline in new tax-exempt bond
issuance has remained a positive factor within the municipal bond
market, as it had been for much of the past year. During the last
six months, more than $110 billion in long-term municipal bonds was
issued, a decline of almost 20% compared to the same period a year
ago. During the past three months, $55 billion in municipal bonds
was underwritten, representing a decline of nearly 10% compared to
the corresponding period in 1998. Additionally, in June and July,
investors received more than $40 billion in coupon income and
proceeds from bond maturities and early bond redemptions. These
proceeds have generated considerable retail investor interest, which
has helped absorb the recent diminished supply.


MuniYield Insured Fund, Inc.
October 31, 1999


Although tax-exempt bond yields are at their highest level in over
two years and have attracted significant retail investor interest,
institutional demand has declined sharply. Long-term municipal
mutual funds have seen consistent outflows in recent months as the
yields of individual securities have risen faster than those of
larger, more diverse mutual funds. In addition, the demand from
property/casualty insurance companies has weakened as a result of
the losses, and anticipated losses, incurred as a result of the
series of damaging storms across much of the eastern United States.
Additionally, many institutional investors who were attracted to the
municipal bond market in recent years by historically attractive tax-
exempt bond yield ratios of over 90% have found other asset classes
even more attractive. Even with a reduced supply position, tax-
exempt issuers have been forced to repeatedly raise municipal bond
yields in the attempt to attract adequate demand.

The recent relative underperformance of the municipal bond market
has resulted in an opportunity for long-term investors to purchase
tax-exempt issues whose yields are nearly identical to taxable US
Treasury securities. At October 31, 1999, long-term uninsured
municipal revenue bond yields were 100% of comparable US Treasury
securities. In recent months, many taxable asset classes, such as
corporate bonds, mortgage-backed securities and US agency debt, have
all accelerated debt issuance. This acceleration was initiated
largely to avoid issuing securities at year-end and to minimize any
associated Year 2000 (Y2K) problems that may develop. However, this
increased issuance has also resulted in higher yield levels in the
various asset classes as lower bond prices became necessary to
attract sufficient investor demand. Going forward, it is believed
that the pace of non-US Government debt issuance is likely to slow
significantly. As the supply of this debt declines, we would expect
many institutional investors to return to the municipal bond market
and the attractive yield ratios available.

Looking ahead, it appears to us that long-term municipal bond yields
will remain under pressure, trading in a broad range centered near
current levels. Investors are likely to remain concerned about
future action by the Federal Reserve Board. Y2K considerations may
prohibit any further Federal Reserve Board moves through the end of
the year and the beginning of 2000. Any improvement in bond prices
will probably be contingent upon weakening in both US employment
growth and consumer spending. The 100 basis point rise in US
Treasury bond yields seen thus far this year may negatively affect
US economic growth. The US housing market will be among the first
sectors likely to be affected, as some declines have already been
evidenced in response to higher mortgage rates. We believe that it
is also unrealistic to expect double-digit returns in US equity
markets to continue indefinitely. Much of the US consumer's wealth
is tied to recent stock market appreciation. Any slowing in these
incredible growth rates is likely to reduce consumer spending. We
believe that these factors suggest that the worst of the recent
increase in bond yields has passed and stable, if not slightly
improving, bond prices may be expected.


Portfolio Strategy
During the fiscal year ended October 31, 1999, we held a neutral
investment strategy, since indicators pointed to a continuation of
both benign inflation and healthy domestic economic growth. These
favorable conditions led us to believe that long-term tax-exempt
bond yields would continue trading within a somewhat narrow range.
Therefore, we chose to focus on income-producing securities rather
than on those with the potential for capital gains. We believed that
coupon income could potentially be the more significant segment of
the Fund's annual total return performance if the tax-exempt bond
market performed as anticipated. Keeping shareholder income in mind,
the Fund remained fully invested for most of the past several
months, and we expect to maintain this position going forward.

Short-term tax-exempt yields exhibited considerable volatility
during the Fund's fiscal year. Interest rates paid to the Preferred
Stock shareholders traded below 3% in December 1998, reflecting
heightened investor demand at year-end. However, throughout fiscal
year ended October 31, 1999, leveraging generated a significant
incremental yield to the Fund's Common Stock shareholders. Because
we believe Federal Reserve Board policy is likely to remain stable
for the rest of the year, we expect short-term tax-exempt interest
rates to remain at, or slightly below, current levels. However,
should the spread between long-term interest rates and short-term
interest rates narrow, the benefits of the leverage will decline and
the yield on the Common Stock will decline. (For a complete
explanation of the benefits and risks of leveraging, see page 5 of
this report to shareholders.)

THE BENEFITS AND RISKS OF LEVERAGING


MuniYield Insured Fund, Inc. utilizes leveraging to seek to enhance
the yield and net asset value of its Common Stock. However, these
objectives cannot be achieved in all interest rate environments. To
leverage, the Fund issues Preferred Stock, which pays dividends at
prevailing short-term interest rates and invests the proceeds in
long-term municipal bonds. The interest earned on these investments
is paid to Common Stock shareholders in the form of dividends, and
the value of these portfolio holdings is reflected in the per share
net asset value of the Fund's Common Stock. However, in order to
benefit Common Stock shareholders, the yield curve must be
positively sloped; that is, short-term interest rates must be lower
than long-term interest rates. At the same time, a period of
generally declining interest rates will benefit Common Stock
shareholders. If either of these conditions change, then the risks
of leveraging will begin to outweigh the benefits.

To illustrate these concepts, assume a fund's Common Stock
capitalization of $100 million and the issuance of Preferred Stock
for an additional $50 million, creating a total value of $150
million available for investment in long-term municipal bonds. If
prevailing short-term interest rates are approximately 3% and long-
term interest rates are approximately 6%, the yield curve has a
strongly positive slope. The fund pays dividends on the $50 million
of Preferred Stock based on the lower short-term interest rates. At
the same time, the fund's total portfolio of $150 million earns the
income based on long-term interest rates. Of course, increases in
short-term interest rates would reduce (and even eliminate) the
dividends on the Common Stock.

In this case, the dividends paid to Preferred Stock shareholders are
significantly lower than the income earned on the fund's long-term
investments, and therefore the Common Stock shareholders are the
beneficiaries of the incremental yield. However, if short-term
interest rates rise, narrowing the differential between short-term
and long-term interest rates, the incremental yield pickup on the
Common Stock will be reduced or eliminated completely. At the same
time, the market value of the fund's Common Stock (that is, its
price as listed on the New York Stock Exchange) may, as a result,
decline. Furthermore, if long-term interest rates rise, the Common
Stock's net asset value will reflect the full decline in the price
of the portfolio's investments, since the value of the fund's
Preferred Stock does not fluctuate. In addition to the decline in
net asset value, the market value of the fund's Common Stock may
also decline.

As a part of its investment strategy, the Fund may invest in certain
securities whose potential income return is inversely related to
changes in a floating interest rate ("inverse floaters"). In
general, income on inverse floaters will decrease when short-term
interest rates increase and increase when short-term interest rates
decrease. Investments in inverse floaters may be characterized as
derivative securities and may subject the Fund to the risks of
reduced or eliminated interest payments and losses of invested
principal. In addition, inverse floaters have the effect of
providing investment leverage and, as a result, the market value of
such securities will generally be more volatile than that of fixed-
rate, tax-exempt securities. To the extent the Fund invests in
inverse floaters, the market value of the Fund's portfolio and the
net asset value of the Fund's shares may also be more volatile than
if the Fund did not invest in these securities.

MANAGED DIVIDEND POLICY


The Fund's dividend policy is to distribute substantially all of its
net investment income to its shareholders on a monthly basis.
However, in order to provide shareholders with a more consistent
yield to the current trading price of shares of Common Stock of the
Fund, the Fund may at times pay out less than the entire amount of
net investment income earned in any particular month and may at
times in any month pay out such accumulated but undistributed income
in addition to net investment income earned in that month. As a
result, the dividends paid by the Fund for any particular month may
be more or less than the amount of net investment income earned by
the Fund during such month. The Fund's current accumulated but
undistributed net investment income, if any, is disclosed in the
Statement of Assets, Liabilities and Capital, which comprises part
of the Financial Information included in this report.


YEAR 2000 ISSUES (UNAUDITED)


Many computer systems were designed using only two digits to
designate years. These systems may not be able to distinguish the
Year 2000 from the Year 1900 (commonly known as the "Year 2000
Problem"). The Fund could be adversely affected if the computer
systems used by the Fund's management or other Fund service
providers do not properly address this problem before January 1,
2000. The Fund's management expects to have addressed this problem
before then, and does not anticipate that the services it provides
will be adversely affected. The Fund's other service providers have
told the Fund's management that they also expect to resolve the Year
2000 Problem, and the Fund's management will continue to monitor the
situation as the Year 2000 approaches. However, if the problem has
not been fully addressed, the Fund could be negatively affected. The
Year 2000 Problem could also have a negative impact on the
securities in which the Fund invests, and this could hurt the Fund's
investment returns.

NOTES TO FINANCIAL STATEMENTS


1. Significant Accounting Policies:
MuniYield Insured Fund, Inc. (the "Fund") is registered under the
Investment Company Act of 1940 as a non-diversified, closed-end
management investment company. The Fund's financial statements are
prepared in accordance with generally accepted accounting
principles, which may require the use of management accruals and
estimates. The Fund determines and makes available for publication
the net asset value of its Common Stock on a weekly basis. The
Fund's Common Stock is listed on the New York Stock Exchange under
the symbol MYI. The following is a summary of significant accounting
policies followed by the Fund.

(a) Valuation of investments--Municipal bonds are traded primarily
in the over-the-counter markets and are valued at the most recent
bid price or yield equivalent as obtained by the Fund's pricing
service from dealers that make markets in such securities. Financial
futures contracts and options thereon, which are traded on
exchanges, are valued at their closing prices as of the close of
such exchanges. Options written or purchased are valued at the last
sale price in the case of exchange-traded options. In the case of
options traded in the over-the-counter market, valuation is the last
asked price (options written) or the last bid price (options
purchased). Securities with remaining maturities of sixty days or
less are valued at amortized cost, which approximates market value.
Securities and assets for which market quotations are not readily
available are valued at fair value as determined in good faith by or
under the direction of the Board of Directors of the Fund, including
valuations furnished by a pricing service retained by the Fund,
which may utilize a matrix system for valuations. The procedures of
the pricing service and its valuations are reviewed by the officers
of the Fund under the general supervision of the Board of Directors.

(b) Derivative financial instruments--The Fund may engage in various
portfolio strategies to seek to increase its return by hedging its
portfolio against adverse movements in the debt markets. Losses may
arise due to changes in the value of the contract or if the
counterparty does not perform under the contract.

* Financial futures contracts--The Fund may purchase or sell
financial futures contracts and options on such futures contracts
for the purpose of hedging the market risk on existing securities or
the intended purchase of securities. Futures contracts are contracts
for delayed delivery of securities at a specific future date and at
a specific price or yield. Upon entering into a contract, the Fund
deposits and maintains as collateral such initial margin as required
by the exchange on which the transaction is effected. Pursuant to
the contract, the Fund agrees to receive from or pay to the broker
an amount of cash equal to the daily fluctuation in value of the
contract. Such receipts or payments are known as variation margin
and are recorded by the Fund as unrealized gains or losses. When the
contract is closed, the Fund records a realized gain or loss equal
to the difference between the value of the contract at the time it
was opened and the value at the time it was closed.

* Options--The Fund is authorized to write covered call options and
purchase put options. When the Fund writes an option, an amount
equal to the premium received by the Fund is reflected as an asset
and an equivalent liability. The amount of the liability is
subsequently marked to market to reflect the current market value of
the option written.

When a security is purchased or sold through an exercise of an
option, the related premium paid (or received) is added to (or
deducted from) the basis of the security acquired, or deducted from
(or added to) the proceeds of the security sold. When an option
expires (or the Fund enters into a closing transaction), the Fund
realizes a gain or loss on the option to the extent of the premiums
received or paid (or gain or loss to the extent the cost of the
closing transaction exceeds the premium paid or received).

Written and purchased options are non-income producing investments.

(c) Income taxes--It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated
investment companies and to distribute substantially all of its
taxable income to its shareholders. Therefore, no Federal income tax
provision is required.

(d) Security transactions and investment income--Security
transactions are recorded on the dates the transactions are entered
into (the trade dates). Interest income is recognized on the accrual
basis. Discounts and market premiums are amortized into interest
income. Realized gains and losses on security transactions are
determined on the identified cost basis.

NOTES TO FINANCIAL STATEMENTS (concluded)


(e) Dividends and distributions--Dividends from net investment
income are declared and paid monthly. Distributions of capital gains
are recorded on the ex-dividend dates. Distributions in excess of
realized capital gains are due primarily to differing tax treatments
for futures transactions.

(f) Reclassification--Generally accepted accounting principles
require that certain components of net assets be adjusted to reflect
permanent differences between financial and tax reporting.
Accordingly, current year's permanent book/tax differences of $622
have been reclassified between accumulated distributions in excess
of net realized capital gains and undistributed net investment
income. These reclassifications have no effect on net assets or net
asset value per share.

2. Investment Advisory Agreement and
Transactions with Affiliates:
The Fund has entered into an Investment Advisory Agreement with Fund
Asset Management, L.P. ("FAM"). The general partner of FAM is
Princeton Services, Inc. ("PSI"), an indirect wholly-owned
subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the
limited partner.

FAM is responsible for the management of the Fund's portfolio and
provides the necessary personnel, facilities, equipment and certain
other services necessary to the operations of the Fund. For such
services, the Fund pays a monthly fee at an annual rate of .50% of
the Fund's average weekly net assets, including proceeds from the
issuance of Preferred Stock.

Accounting services are provided to the Fund by FAM at cost.

Certain officers and/or directors of the Fund are officers and/or
directors of FAM, PSI, and/or ML & Co.

3. Investments:
Purchases and sales of investments, excluding short-term securities,
for the year ended October 31, 1999 were $1,595,468,238 and

depreciated securities. The aggregate cost of investments at October
31, 1999 for Federal income tax purposes was $1,326,347,422.

4. Capital Stock Transactions:
The Fund is authorized to issue 200,000,000 shares of capital stock,
including Preferred Stock, par value $.10 per share, all of which
were initially classified as Common Stock. The Board of Directors is
authorized, however, to reclassify any unissued shares of capital
stock without approval of the holders of Common Stock.

Common Stock
Shares issued and outstanding during the year ended October 31, 1999
increased by 594,744 as a result of dividend reinvestment and during
the year ended October 31, 1998 remained constant.

Preferred Stock
Auction Market Preferred Stock ("AMPS") are shares of Preferred
Stock of the Fund, with a par value of $.10 per share and a
liquidation preference of $25,000 per share, that entitle their
holders to receive cash dividends at an annual rate that may vary
for the successive dividend periods. The yields in effect at October
31, 1999 were as follows: Series A, 3.45%; Series B, 3.479%; Series
C, 3.44%; Series D, 3.375%; Series E, 3.40%; Series F, 3.444%; and
Series G, 3.25%.

Shares issued and outstanding during the years ended October 31,
1999 and October 31, 1998 remained constant.

The Fund pays commissions to certain broker-dealers at the end of
each auction at an annual rate ranging from .25% to .375%,
calculated on the proceeds of each auction. For the year ended
October 31, 1999, Merrill Lynch, Pierce, Fenner & Smith
Incorporated, an affiliate of FAM, earned $340,415 as commissions.

5. Capital Loss Carryforward:
At October 31, 1999, the Fund had a net capital loss carryforward of
approximately $24,114,000, all of which expires in 2007. This amount
will be available to offset like amounts of any future taxable
gains.

6. Subsequent Event:
On November 8, 1999, the Fund's Board of Directors declared an
ordinary income dividend to Common Stock shareholders in the amount
of $.073000 per share, payable on November 29, 1999 to shareholders
of record as of November 22, 1999.
