PRESIDENT'S MESSAGE
 
 
(PHOTO_OF_EDWARD_C_JOHNSON_3D)DEAR SHAREHOLDER:
What a difference one month can make. The stock and bond markets did
an about-face in October, as renewed optimism in many emerging markets
and more encouraging corporate earnings forecasts in the U.S. replaced
the concerns that had shaped the financial markets in recent months.
Equity markets worldwide bounced back strongly, while the major U.S.
bond indexes were off slightly as the flight to safety eased. 
While it's impossible to predict the future direction of the markets
with any degree of certainty, there are certain basic principles that
can help investors plan for their future needs.
The longer your investment time frame, the less likely it is that you
will be affected by short-term market volatility. A 10-year investment
horizon appropriate for saving for a college education, for example,
enables you to weather market cycles in a long-term fund, which may
have a higher risk potential, but also has a higher potential rate of
return.
An intermediate-length fund could make sense if your investment
horizon is two to four years, while a short-term bond fund could be
the right choice if you need your money in one or two years.
If your time horizon is less than a year, you might want to consider
moving some of your bond investment into a money market fund. These
funds seek income and a stable share price by investing in
high-quality, short-term investments. Of course, it's important to
remember that there is no assurance that a money market fund will
achieve its goal of maintaining a stable net asset value of $1.00 per
share, and that these types of funds are neither insured nor
guaranteed by any agency of the U.S. government.
Finally, no matter what your time horizon or portfolio diversity, it
makes good sense to follow a regular investment plan, investing a
certain amount of money in a fund at the same time each month or
quarter and periodically reviewing your overall portfolio. By doing
so, you won't get caught up in the excitement of a rapidly rising
market, nor will you buy all your shares at market highs. While this
strategy - known as dollar cost averaging - won't assure a profit or
protect you from a loss in a declining market, it should help you
lower the average cost of your purchases. Of course, you should
consider your financial ability to continue your purchases through
periods of low price levels before undertaking such a strategy.
Remember to contact your investment professional if you need help with
your investments.
Best regards,
Edward C. Johnson 3d
 
FIDELITY ADVISOR MORTGAGE SECURITIES FUND - CLASS A
PERFORMANCE: THE BOTTOM LINE
 
 
There are several ways to evaluate historical performance. You can
look at the total percentage change in value, the average annual
percentage change or the growth of a hypothetical $10,000 investment.
Total return reflects the change in the value of an investment,
assuming reinvestment of the class' dividend income and capital gains
(the profits earned upon the sale of securities that have grown in
value). You can also look at the class' income, as reflected in its
yield, to measure performance. The initial offering of Class A shares
took place on March 3, 1997. Class A shares bear a 0.15% 12b-1 fee.
Returns prior to March 3, 1997 are those of Initial Class, the
original class of the fund which does not bear a 12b-1 fee. Had Class
A shares' 12b-1 fee been reflected, returns prior to March 3, 1997
would have been lower. If Fidelity had not reimbursed certain class
expenses, the total returns and dividends would have been lower.

US MORTGAGE FUNDS AVERAGE                     6.62%   32.38%  111.59%  
 
CUMULATIVE TOTAL RETURNS show Class A's performance in percentage
terms over a set period - in this case, one year, five years or 10
years. For example, if you had invested $1,000 in a fund that had a 5%
return over the past year, the value of your investment would be
$1,050. You can compare Class A's returns to the performance of the
Lehman Brothers Mortgage-Backed Securities Index - a market
capitalization weighted index of 15- and 30-year fixed-rate securities
backed by mortgage pools of Ginnie Mae (GNMA), Fannie Mae (FNMA) and
Freddie Mac (FHLMC), and FNMA and FHLMC balloon mortgages with
fixed-rate coupons. To measure how Class A's performance stacked up
against its peers, you can compare it to the U.S. mortgage funds
average, which reflects the performance of mutual funds with similar
objectives tracked by Lipper Analytical Services, Inc. The past one
year average represents a peer group of 68 mutual funds. These
benchmarks reflect reinvestment of dividends and capital gains, if
any, and exclude the effect of sales charges.

$10,000 OVER 10 YEARS: Let's say hypothetically that $10,000 was
invested in Fidelity Advisor Mortgage Securities Fund - Class A on
October 31, 1988, and the current 4.75% sales charge was paid. As the
chart shows, by October 31, 1998, the value of the investment would
have grown to $21,428 - a 114.28% increase on the initial investment.
For comparison, look at how the Lehman Brothers Mortgage-Backed
Securities Index did over the same period. With dividends and capital
gains, if any, reinvested, the same $10,000 would have grown to
$23,261 - a 132.61% increase.
 
UNDERSTANDING
PERFORMANCE
HOW A FUND DID YESTERDAY IS 
NO GUARANTEE OF HOW IT WILL DO 
TOMORROW. BOND PRICES, FOR 
EXAMPLE, GENERALLY MOVE IN THE 
OPPOSITE DIRECTION OF INTEREST 
RATES. IN TURN, THE SHARE PRICE, 
RETURN AND YIELD OF A FUND THAT 
INVESTS IN BONDS WILL VARY. THAT 
MEANS IF YOU SELL YOUR SHARES 
DURING A MARKET DOWNTURN, YOU 
MIGHT LOSE MONEY. BUT IF YOU CAN 
RIDE OUT THE MARKET'S UPS AND 
DOWNS, YOU MAY HAVE A GAIN.

TOTAL RETURN COMPONENTS include both dividend returns and capital

class. A capital return reflects both the amount paid by the class to
shareholders as capital gain distributions and changes in the class'
share price. Both returns assume the dividends or capital gains paid
by the class are reinvested, if any, and exclude the effect of sales
charges.

DIVIDENDS per share show the income paid by the class for a set
period. If you annualize this number, based on an average share price
of $11.03 over the past one month, $11.04 over the past six months,
and $11.03 over the past one year, you can compare the class' income
over these three periods. The 30-day annualized YIELD is a standard
formula for all funds based on the yields of the bonds in the fund,
averaged over the past 30 days. This figure shows you the yield
characteristics of the fund's investments at the end of the period. It
also helps you compare funds from different companies on an equal
basis. Yield information will be reported once Class A has a longer,
more stable operating history.
 
FIDELITY ADVISOR MORTGAGE SECURITIES FUND - CLASS T
PERFORMANCE: THE BOTTOM LINE
 
 
There are several ways to evaluate historical performance. You can
look at the total percentage change in value, the average annual
percentage change or the growth of a hypothetical $10,000 investment.
Total return reflects the change in the value of an investment,
assuming reinvestment of the class' dividend income and capital gains
(the profits earned upon the sale of securities that have grown in
value). You can also look at the class' income, as reflected in its
yield, to measure performance. The initial offering of Class T shares
took place on March 3, 1997. Class T shares bear a 0.25% 12b-1 fee.
Returns prior to March 3, 1997 are those of Initial Class, the
original class of the fund which does not bear a 12b-1 fee. Had Class
T shares' 12b-1 fee been reflected, returns prior to March 3, 1997
would have been lower. If Fidelity had not reimbursed certain class
expenses, the total returns and dividends would have been lower.

US MORTGAGE FUNDS AVERAGE                     6.62%   32.38%  111.59%  
 
CUMULATIVE TOTAL RETURNS show Class T's performance in percentage
terms over a set period - in this case, one year, five years or 10
years. For example, if you had invested $1,000 in a fund that had a 5%
return over the past year, the value of your investment would be
$1,050. You can compare Class T's returns to the performance of the
Lehman Brothers Mortgage-Backed Securities Index - a market
capitalization weighted index of 15- and 30-year fixed-rate securities
backed by mortgage pools of the Ginnie Mae (GNMA), Fannie Mae (FNMA)
and Freddie Mac (FHLMC), and FNMA and FHLMC balloon mortgages with
fixed-rate coupons. To measure how Class T's performance stacked up
against its peers, you can compare it to the U.S. mortgage funds
average, which reflects the performance of mutual funds with similar
objectives tracked by Lipper Analytical Services, Inc. The past one
year average represents a peer group of 68 mutual funds. These
benchmarks reflect reinvestment of dividends and capital gains, if
any, and exclude the effect of sales charges.

$10,000 OVER 10 YEARS: Let's say hypothetically that $10,000 was
invested in Fidelity Advisor Mortgage Securities Fund - Class T on
October 31, 1988, and the current 3.50% sales charge was paid. As the
chart shows, by October 31, 1998, the value of the investment would
have grown to $21,686 - a 116.86% increase on the initial investment.
For comparison, look at how the Lehman Brothers Mortgage-Backed
Securities Index did over the same period. With dividends and capital
gains, if any, reinvested, the same $10,000 would have grown to
$23,261 - a 132.61% increase.
 
UNDERSTANDING
PERFORMANCE
HOW A FUND DID YESTERDAY IS 
NO GUARANTEE OF HOW IT WILL DO 
TOMORROW. BOND PRICES, FOR 
EXAMPLE, GENERALLY MOVE IN THE 
OPPOSITE DIRECTION OF INTEREST 
RATES. IN TURN, THE SHARE PRICE, 
RETURN AND YIELD OF A FUND THAT 
INVESTS IN BONDS WILL VARY. THAT 
MEANS IF YOU SELL YOUR SHARES 
DURING A MARKET DOWNTURN, YOU 
MIGHT LOSE MONEY. BUT IF YOU CAN 
RIDE OUT THE MARKET'S UPS AND 
DOWNS, YOU MAY HAVE A GAIN.

TOTAL RETURN COMPONENTS include both dividend returns and capital
returns. A dividend return reflects the actual dividends paid by the
class. A capital return reflects both the amount paid by the class to
shareholders as capital gain distributions and changes in the class'
share price. Both returns assume the dividends or capital gains paid
by the class are reinvested, if any, and exclude the effect of sales
charges.

DIVIDENDS per share show the income paid by the class for a set
period. If you annualize this number, based on an average share price
of $11.03 over the past one month, $11.04 over the past six months,
and $11.03 over the past one year, you can compare the class' income
over these three periods. The 30-day annualized YIELD is a standard
formula for all funds based on the yields of the bonds in the fund,
averaged over the past 30 days. This figure shows you the yield
characteristics of the fund's investments at the end of the period. It
also helps you compare funds from different companies on an equal
basis. If Fidelity had not reimbursed certain class expenses, the
yield would have been 5.67%.
 
FIDELITY ADVISOR MORTGAGE SECURITIES FUND - CLASS B
PERFORMANCE: THE BOTTOM LINE
 
 
There are several ways to evaluate historical performance. You can
look at the total percentage change in value, the average annual
percentage change or the growth of a hypothetical $10,000 investment.
Total return reflects the change in the value of an investment,
assuming reinvestment of the class' dividend income and capital gains
(the profits earned upon the sale of securities that have grown in
value). You can also look at the class' income, as reflected in its
yield, to measure performance. The initial offering of Class B shares
took place on March 3, 1997. Class B shares bear a .90% 12b-1 fee.
Returns prior to March 3, 1997 are those of Initial Class, the
original class of the fund, which does not bear a 12b-1 fee. Had Class
B shares' 12b-1 fee been reflected, returns prior to March 3, 1997
would have been lower. Class B's contingent deferred sales charges
included in the past one year, past five years and past 10 years total
return figures are 5%, 2% and 0%, respectively. If Fidelity had not
reimbursed certain class expenses, the total returns and dividends
would have been lower.

US MORTGAGE FUNDS AVERAGE                       6.62%   32.38%  111.59%  
 
CUMULATIVE TOTAL RETURNS show Class B's performance in percentage
terms over a set period - in this case, one year, five years or 10
years. For example, if you had invested $1,000 in a fund that had a 5%
return over the past year, the value of your investment would be
$1,050. You can compare Class B's returns to the performance of the
Lehman Brothers Mortgage-Backed Securities Index - a market
capitalization weighted index of 15- and 30-year fixed-rate securities
backed by mortgage pools of the Ginnie Mae (GNMA), Fannie Mae (FNMA)
and Freddie Mac (FHLMC), and FNMA and FHLMC balloon mortgages with
fixed-rate coupons. To measure how Class B's performance stacked up
against its peers, you can compare it to the U.S. mortgage funds
average, which reflects the performance of mutual funds with similar
objectives tracked by Lipper Analytical Services, Inc. The past one
year average represents a peer group of 68 mutual funds. These
benchmarks reflect reinvestment of dividends and capital gains, if
any, and exclude the effect of sales charges.

$10,000 OVER 10 YEARS: Let's say hypothetically that $10,000 was
invested in Fidelity Advisor Mortgage Securities Fund - Class B on
October 31, 1988. As the chart shows, by October 31, 1998, the value
of the investment would have grown to $22,209 - a 122.09% increase on
the initial investment. For comparison, look at how the Lehman
Brothers Mortgage-Backed Securities Index did over the same period.
With dividends and capital gains, if any, reinvested, the same $10,000
would have grown to $23,261 - a 132.61% increase.

FUND TALK: THE MANAGER'S OVERVIEW
 
 
 
MARKET RECAP
Uncertainty in the global equity 
markets, combined with two 
interest-rate cuts by the Federal 
Reserve Board, provided the 
backdrop for strong gains in the 
bond market during the 12-month 
period ended October 31, 1998. The 
Lehman Brothers Aggregate Bond 
Index - a broad measure of the U.S. 
taxable investment-grade bond 
market - returned 9.34% over the 
past year. Global market volatility, 
low interest rates and a sharp 
decline in stock prices sent U.S. 
Treasury yields - which move in the 
opposite direction of bond prices - 
to their lowest levels in 30 years. 
While the extreme flight to quality 
helped Treasuries outperform all 
other sectors of the bond market, 
corporate bond investors benefited 
from a stable domestic economy, 
low interest rates and low inflation. 
The Lehman Brothers Corporate 
Bond Index returned 7.99% for the 
past 12 months. Despite high 
refinancing activity, mortgage bonds 
also performed well. The Lehman 
Brothers Mortgage-Backed Securities 
Index posted a 12-month return of 
7.30%. Late in the period, the bond 
market stumbled as the Group of 
Seven leading industrial nations 
eased global market fears with 
announcements that the International 
Monetary Fund would establish a 
precautionary line of credit to help 
certain countries resolve their 
financial crises. In spite of weakness 
toward the end of the period, the 
yield on the benchmark 30-year 
Treasury closed at 5.15%.
An interview with Tom Silvia, Portfolio Manager of Fidelity Advisor
Mortgage Securities Fund
Q. HOW DID THE FUND PERFORM, TOM?
A. For the 12 months that ended October 31, 1998, the fund's Class A,
Class T and Class B shares returned 5.65%, 5.60% and 4.82%,
respectively. During the same period, the U.S. mortgage funds average,
according to Lipper Analytical Services, returned 6.62%, and the
Lehman Brothers Mortgage-Backed Securities Index returned 7.30%.
Q. HOW WOULD YOU CHARACTERIZE THE MORTGAGE MARKET OVER THE PAST 12
MONTHS?
A. During the first six months of the period, the mortgage market was
surprisingly strong. Low inflation and enormous foreign demand for
U.S. government securities in the wake of the Asian economic crisis
bid Treasury prices up, pushing the 10-year yield down to 5.35% early
in 1998. Falling interest rates usually cause mortgage prices to lag
Treasuries because of increased prepayment risk. As interest rates
fall, many borrowers refinance their home loans, returning the
principal to investors who may have to reinvest at lower rates.
Despite these conditions, investors were attracted by the relatively
high yields offered by mortgage securities. However, the mortgage
market changed direction during the second half of the period.
Emerging monetary and political problems in Russia renewed concern
about the unstable conditions in Asia. Bond-market investors became
less tolerant of risk and sold mortgage securities in favor of
higher-quality, more liquid government securities, flooding the market
with mortgage supply. Interest rates fell to historic low levels,
increasing prepayment risk, which further depressed demand for
mortgage securities. Market liquidity declined substantially and
prices stagnated. Yield spreads reached their widest point in over 10
years as investors required significantly higher rates to choose
mortgages over Treasury securities. 
Q. WHAT WAS YOUR INVESTMENT STRATEGY THROUGHOUT THE PERIOD?
A. My overall objective was to limit relative prepayment risk. My
strategy is based on a disciplined process that first evaluates the
Lehman Brothers index, the fund's performance benchmark. Next, I
allocate assets among the agency sectors based on my assessment of
relative value. During the period, I overweighted Ginnie Mae-issued
mortgages, which were experiencing slower prepayment rates relative to
Fannie Mae and Freddie Mac mortgages. In addition, Ginnie Mae loans
are explicitly guaranteed by the U.S. Treasury. Once sector weights
are determined, I select specific securities. For example, as interest
rates fell, I emphasized seasoned mortgages that had weathered several
prepayment cycles, as well as brand-new mortgages issued at lower
rates that I thought would carry less refinancing risk. Finally, I
look at sectors outside of the index, such as non-agency securities,
commercial mortgages, collateralized mortgage obligations and
adjustable-rate mortgages. For much of the year, I had a significant
proportion of the fund's assets invested in commercial mortgage
securities (CMS). The loans underlying CMS usually have prepayment
restrictions built into their structure, so they can help reduce a
fund's prepayment risk when interest rates are falling.
Q. WEREN'T THERE PROBLEMS IN THE COMMERCIAL MORTGAGE SECTOR DURING THE
YEAR?
A. Yes, there were. During the final months of the period, CMS
dramatically underperformed other types of mortgage securities.
Although they have lower prepayment risk, CMS have greater credit
risk. As a result, this sector was hurt when investors shifted their
preference to very liquid, high-quality instruments such as Treasury
securities. In addition, many hedge funds and real estate investment
trusts had borrowed heavily to purchase relatively high-yielding
securities such as CMS. However, as global credit concerns caused the
CMS sector to weaken, these investors were left holding billions of
dollars of securities that could only be sold at higher yields. Forced
selling of this sector to cover loans reduced liquidity, and prices
fell further. Because the fund was overweighted in commercial
mortgages relative to its benchmark and its peers, CMS were the
largest contributor to the fund's disappointing 12-month total return.
Q. DID YOU REDUCE YOUR CMS EXPOSURE?
A. No, I didn't. I believe that the CMS sector has been oversold. I
haven't seen any fundamental reason to withdraw from this market.
Furthermore, this sector continues to offer good protection against
prepayment risk, which is my primary investment strategy. 
Q. WHAT'S YOUR OUTLOOK FOR THE COMING MONTHS? 
A. I am taking a cautious approach to the market. As long as interest
rates have the possibility to fall further, prepayment risk will
continue to limit mortgage securities performance. I plan to emphasize
the fund's defensive characteristics until there are conclusive
changes in the economy's direction.

TOM SILVIA ON COMMERCIAL 
MORTGAGE SECURITIES (CMS):
"The CMS market has been among 
the fastest growing sectors of the 
fixed-income market. CMS are bonds 
that are collateralized by mortgage 
loans on commercial real estate 
such as office buildings, shopping 
malls, hotels and apartment 
buildings. This market sector was 
created in the mid 1980s, and 
today the amount of commercial 
mortgage loans outstanding in the 
United States is approximately $1.5 
trillion. 
"Commercial mortgages differ from 
the mortgage securities comprising 
the fund's performance benchmark, 
the Lehman Brothers 
Mortgage-Backed Securities 
Index. The index is made up of 
single-family home mortgages 
issued by one of three housing 
agencies - Ginnie Mae (GNMA), 
Fannie Mae (FNMA) and Freddie 
Mac (FHLMC). Agency mortgage 
securities have minimal credit risk 
and carry an implied triple-A 
rating because of their relationship 
with the U.S. Treasury. GNMA 
securities are guaranteed by the 
government, while FNMA and 
FHLMC securities carry an implied 
guarantee. CMS are privately 
issued and are not supported by the 
government. The primary advantage 
of investing in commercial versus 
agency single-family mortgages is 
related to prepayment risk. 
Commercial mortgages typically 
have some form of prepayment 
protection because commercial 
borrowers are usually restricted 
from early loan payoffs. Thus, CMS 
provide an efficient way to reduce 
a portfolio's prepayment risk, 
particularly in periods when 
interest rates are falling."

DURATION SHOWS HOW MUCH A BOND FUND'S PRICE FLUCTUATES WITH CHANGES IN
COMPARABLE INTEREST RATES. IF RATES RISE 1%, FOR EXAMPLE, A FUND WITH
A FIVE-YEAR DURATION IS LIKELY TO LOSE ABOUT 5% OF ITS VALUE. OTHER
FACTORS ALSO CAN INFLUENCE A BOND FUND'S PERFORMANCE AND SHARE PRICE. 
ACCORDINGLY, A BOND FUND'S ACTUAL PERFORMANCE MAY DIFFER FROM THIS
EXAMPLE.

1. SIGNIFICANT ACCOUNTING POLICIES.
Fidelity Advisor Mortgage Securities Fund (the fund) is a fund of
Fidelity Income Fund (the trust) and is authorized to issue an
unlimited number of shares. The trust is registered under the
Investment Company Act of 1940, as amended (the 1940 Act), as an
open-end management investment company organized as a Massachusetts
business trust.
The fund offers Class A, Class T, Class B, Initial Class, and
Institutional Class shares, each of which has equal rights as to
assets and voting privileges. Each class has exclusive voting rights
with respect to matters that affect that class. Class B shares will
automatically convert to Class A shares after a holding period of
seven years from the initial date of purchase. Interest income,
realized and unrealized capital gains and losses, the common expenses
of the fund, and certain fund-level expense reductions, if any, are
allocated on a pro rata basis to each class based on the relative net
assets of each class to the total net assets of the fund. Each class
of shares differs in its respective distribution, transfer agent, and
certain other class-specific fees, expenses, and expense reductions.
The financial statements have been prepared in conformity with
generally accepted accounting principles which require management to
make certain estimates and assumptions at the date of the financial
statements. The following summarizes the significant accounting
policies of the fund:
SECURITY VALUATION. Securities are valued based upon a computerized
matrix system and/or appraisals by a pricing service, both of which
consider market transactions and dealer-supplied valuations.
Securities (including restricted securities) for which quotations are
not readily available are valued primarily using dealer-supplied
valuations or at their fair value as determined in good faith under
consistently applied procedures under the general supervision of the
Board of Trustees. Short-term securities with remaining maturities of
sixty days or less for which quotations are not readily available are
valued at amortized cost or original cost plus accrued interest, both
of which approximate current value.
INCOME TAXES. As a qualified regulated investment company under
Subchapter M of the Internal Revenue Code, the fund is not subject to
income taxes to the extent that it distributes substantially all of
its taxable income for its fiscal year. The schedule of investments
includes information regarding income taxes under the caption "Income
Tax Information."
INVESTMENT INCOME. Interest income, which includes accretion of
original issue discount, is accrued as earned.
EXPENSES. Most expenses of the trust can be directly attributed to a
fund. Expenses which cannot be directly attributed are apportioned
among the funds in the trust.
DISTRIBUTIONS TO SHAREHOLDERS. Distributions are declared daily and
paid monthly from net investment income. Distributions from realized
gains, if any, are recorded on 
1. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED
DISTRIBUTIONS TO SHAREHOLDERS - CONTINUED
the ex-dividend date. Income dividends and capital gain distributions
are declared separately for each class.
Income and capital gain distributions are determined in accordance
with income tax regulations which may differ from generally accepted
accounting principles. These differences, which may result in
distribution reclassifications, are primarily due to differing
treatments for paydown gains/losses on certain securities, futures
transactions and losses deferred due to wash sales. The fund also
utilized earnings and profits distributed to shareholders on
redemption of shares as a part of the dividends paid deduction for
income tax purposes.
Permanent book and tax basis differences relating to shareholder
distributions will result in reclassifications to paid in capital.
Undistributed net investment income and accumulated undistributed net
realized gain (loss) on investments may include temporary book and tax
basis differences which will reverse in a subsequent period. Any
taxable income or gain remaining at fiscal year end is distributed in
the following year.
SECURITY TRANSACTIONS. Security transactions are accounted for as of
trade date. Gains and losses on securities sold are determined on the
basis of identified cost.
2. OPERATING POLICIES.
JOINT TRADING ACCOUNT. Pursuant to an Exemptive Order issued by the
Securities and Exchange Commission, the fund, along with other
affiliated entities of Fidelity Management & Research Company (FMR),
may transfer uninvested cash balances into one or more joint trading
accounts. These balances are invested in one or more repurchase
agreements for U.S. Treasury or Federal Agency obligations.
REPURCHASE AGREEMENTS. The underlying U.S. Treasury or Federal Agency
securities are transferred to an account of the fund, or to the Joint
Trading Account, at a bank custodian. The securities are
marked-to-market daily and maintained at a value at least equal to the
principal amount of the repurchase agreement (including accrued
interest). FMR, the fund's investment adviser, is responsible for
determining that the value of the underlying securities remains in
accordance with the market value requirements stated above. 
DELAYED DELIVERY TRANSACTIONS. The fund may purchase or sell
securities on a delayed delivery basis. Payment and delivery may take
place a month or more after the date of the transaction. The price of
the underlying securities and the date when the securities will be
delivered and paid for are fixed at the time the transaction is
negotiated. The market values of the securities purchased or sold on a
delayed delivery basis are identified as such in the fund's schedule
of investments. The fund may receive

DELAYED DELIVERY TRANSACTIONS - CONTINUED
compensation for interest forgone in the purchase of a delayed
delivery security. With respect to purchase commitments, the fund
identifies securities as segregated in its custodial records with a
value at least equal to the amount of the commitment. Losses may arise
due to changes in the market value of the underlying securities or if
the counterparty does not perform under the contract. 
FUTURES CONTRACTS. The fund may use futures contracts to manage its
exposure to the bond market and to fluctuations in interest rates.
Buying futures tends to increase the fund's exposure to the underlying
instrument, while selling futures tends to decrease the fund's
exposure to the underlying instrument or hedge other fund investments.
Futures contracts involve, to varying degrees, risk of loss in excess
of the futures variation margin reflected in the Statement of Assets
and Liabilities. The underlying face amount at value of any open
futures contracts at period end is shown in the schedule of
investments under the caption "Futures Contracts." This amount
reflects each contract's exposure to the underlying instrument at
period end. Losses may arise from changes in the value of the
underlying instruments or if the counterparties do not perform under
the contracts' terms. Gains (losses) are realized upon the expiration
or closing of the futures contracts. Futures contracts are valued at
the settlement price established each day by the board of trade or
exchange on which they are traded.
RESTRICTED SECURITIES. The fund is permitted to invest in securities
that are subject to legal or contractual restrictions on resale. These
securities generally may be resold in transactions exempt from
registration or to the public if the securities are registered.
Disposal of these securities may involve time-consuming negotiations
and expense, and prompt sale at an acceptable price may be difficult.
At the end of the period, the fund had no investments in restricted
securities (excluding 144A issues).
3. PURCHASES AND SALES OF INVESTMENTS. 
Purchases and sales of long-term U.S. government and government agency
obligations aggregated $1,299,705,940 and $1,306,435,411,
respectively.
The market value of futures contracts opened and closed during the
period amounted to $10,201,804 and $0, respectively.
4. FEES AND OTHER TRANSACTIONS WITH AFFILIATES. 
MANAGEMENT FEE. As the fund's investment adviser, FMR receives a
monthly fee that is calculated on the basis of a group fee rate plus a
fixed individual fund fee rate applied to the average net assets of
the fund. The group fee rate is the weighted average of a series of
rates and is based on the monthly average net assets of all the mutual
funds advised by FMR. 
4. FEES AND OTHER TRANSACTIONS WITH AFFILIATES - CONTINUED
MANAGEMENT FEE - CONTINUED
The rates ranged from .1100% to .3700% for the period. The annual
individual fund fee rate is .30%. In the event that these rates were
lower than the contractual rates in effect during the period, FMR
voluntarily implemented the above rates, as they resulted in the same
or a lower management fee. For the period, the management fee was
equivalent to an annual rate of .44% of average net assets.
DISTRIBUTION AND SERVICE PLAN. In accordance with Rule 12b-1 of the
1940 Act, the Trustees have adopted separate distribution plans with
respect to each class of shares (collectively referred to as "the
Plans"). Under certain of the Plans, the class pays Fidelity
Distributors Corporation (FDC), an affiliate of FMR, a distribution
and service fee. A portion of this fee may be reallowed to securities
dealers, banks and other financial institutions for the distribution
of each class of shares and providing shareholder support services.
For the period, this fee was based on the following annual rates of
the average net assets of each applicable class:
 
CLASS A    .15%   
 
CLASS T    .25%   
 
CLASS B    .90%*  
 
* .65% REPRESENTS A DISTRIBUTION FEE AND .25% REPRESENTS A SHAREHOLDER
SERVICE FEE.
For the period, each class paid FDC the following amounts, a portion
of which was retained by FDC:
 
          PAID TO   RETAINED  
          FDC       BY FDC    
 
CLASS A   $ 1,249   $ 189     
 
CLASS T    36,423    13,984   
 
CLASS B    35,531    25,811   
 
          $ 73,203  $ 39,984  
 
Under the Plans, FMR may use its resources to pay administrative and
promotional expenses related to the sale of each class' shares. The
Plans also authorize payments to third parties that assist in the sale
of each class' shares or render shareholder support services. For the
period, the following amounts were paid to third parties under the
Plans: 
 
CLASS A               $ 107   
 
CLASS T                6,184  
 
CLASS B                415    
 
INSTITUTIONAL CLASS    2,793  
 
4. FEES AND OTHER TRANSACTIONS WITH AFFILIATES - CONTINUED
SALES LOAD. FDC receives a front-end sales charge of up to 4.75% for
selling Class A shares, and 3.50% for selling Class T shares of the
fund. FDC receives the proceeds of contingent deferred sales charges
levied on Class B share redemptions occurring within six years of
purchase. The Class B charge is based on declining rates ranging from
5% to 1% of the lesser of the cost of shares at the initial date of
purchase or the net asset value of the redeemed shares, excluding any
reinvested dividends and capital gains. In addition, purchases of
Class A and Class T shares that were subject to a finder's fee bear a
contingent deferred sales charge on assets that do not remain in the
fund for at least one year. The Class A and Class T contingent
deferred sales charge is based on 0.25% of the lesser of the cost of
shares at the initial date of purchase or the net asset value of the
redeemed shares, excluding any reinvested dividends and capital gains.
A portion of the sales charges paid to FDC are paid to securities
dealers, banks and other financial institutions.
For the period, sales charge amounts paid to and retained by FDC were
as follows:
 
          PAID TO   RETAINED  
          FDC       BY FDC    
 
CLASS A   $ 15,729  $ 5,230

ITS OWN RESOURCES TO SECURITIES DEALERS,
 BANKS, AND OTHER FINANCIAL INSTITUTIONS THROUGH WHICH THE SALES ARE
MADE.

REPORT OF INDEPENDENT ACCOUNTANTS
 
 
To the Trustees of Fidelity Income Fund and the Shareholders of
Fidelity Advisor Mortgage Securities Fund:
In our opinion, the accompanying statement of assets and liabilities,
including the schedule of investments, and the related statements of
operations and of changes in net assets and the financial highlights
present fairly, in all material respects, the financial position of
Fidelity Advisor Mortgage Securities Fund (a fund of Fidelity Income
Fund) at October 31, 1998, the results of its operations, the changes
in its net assets and the financial highlights for the periods
indicated, in conformity with generally accepted accounting
principles. These financial statements and financial highlights
(hereafter referred to as "financial statements") are the
responsibility of  Fidelity Advisor Mortgage Securities Fund 's
management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of
these financial statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are
free of material misstatement. An audit includes examining, on a test
basis, evidence supporting the amounts and disclosures in the
financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which
included confirmation of securities at October 31, 1998 by
correspondence with the custodian and brokers, provide a reasonable
basis for the opinion expressed above.

PRESIDENT'S MESSAGE
 
 
(PHOTO_OF_EDWARD_C_JOHNSON_3D)DEAR SHAREHOLDER:
What a difference one month can make. The stock and bond markets did
an about-face in October, as renewed optimism in many emerging markets
and more encouraging corporate earnings forecasts in the U.S. replaced
the concerns that had shaped the financial markets in recent months.
Equity markets worldwide bounced back strongly, while the major U.S.
bond indexes were off slightly as the flight to safety eased. 
While it's impossible to predict the future direction of the markets
with any degree of certainty, there are certain basic principles that
can help investors plan for their future needs.
The longer your investment time frame, the less likely it is that you
will be affected by short-term market volatility. A 10-year investment
horizon appropriate for saving for a college education, for example,
enables you to weather market cycles in a long-term fund, which may
have a higher risk potential, but also has a higher potential rate of
return.
An intermediate-length fund could make sense if your investment
horizon is two to four years, while a short-term bond fund could be
the right choice if you need your money in one or two years.
If your time horizon is less than a year, you might want to consider
moving some of your bond investment into a money market fund. These
funds seek income and a stable share price by investing in
high-quality, short-term investments. Of course, it's important to
remember that there is no assurance that a money market fund will
achieve its goal of maintaining a stable net asset value of $1.00 per
share, and that these types of funds are neither insured nor
guaranteed by any agency of the U.S. government.
Finally, no matter what your time horizon or portfolio diversity, it
makes good sense to follow a regular investment plan, investing a
certain amount of money in a fund at the same time each month or
quarter and periodically reviewing your overall portfolio. By doing
so, you won't get caught up in the excitement of a rapidly rising
market, nor will you buy all your shares at market highs. While this
strategy - known as dollar cost averaging - won't assure a profit or
protect you from a loss in a declining market, it should help you
lower the average cost of your purchases. Of course, you should
consider your financial ability to continue your purchases through
periods of low price levels before undertaking such a strategy.
Remember to contact your investment professional if you need help with
your investments.
Best regards,
Edward C. Johnson 3d
 
FIDELITY MORTGAGE SECURITIES FUND - INITIAL CLASS
PERFORMANCE: THE BOTTOM LINE
 
 
There are several ways to evaluate historical performance. You can
look at the total percentage change in value, the average annual
percentage change or the growth of a hypothetical $10,000 investment.
Total return reflects the change in the value of an investment,
assuming reinvestment of the class' dividend income and capital gains
(the profits earned upon the sale of securities that have grown in
value). You can also look at the class' income, as reflected in its
yield, to measure performance.

CUMULATIVE TOTAL RETURNS show Initial Class' performance in percentage
terms over a set period - in this case, one year, five years or 10
years. For example, if you had invested $1,000 in a fund that had a 5%
return over the past year, the value of your investment would be
$1,050. You can compare Initial Class' returns to the performance of
the Lehman Brothers Mortgage- Backed Securities Index - a market
capitalization weighted index of 15- and 30-year fixed-rate securities
backed by mortgage pools of Ginnie Mae (GNMA), Fannie Mae (FNMA) and
Freddie Mac (FHLMC), and FNMA and FHLMC balloon mortgages with
fixed-rate coupons. To measure how Initial Class' performance stacked
up against its peers, you can compare it to the U.S. mortgage funds
average, which reflects the performance of mutual funds with similar
objectives tracked by Lipper Analytical Services, Inc. The past one
year average represents a peer group of 68 mutual funds. These
benchmarks reflect reinvestment of dividends and capital gains, if
any, and exclude the effect of sales charges.

$10,000 OVER 10 YEARS: Let's say hypothetically that $10,000 was
invested in Fidelity Advisor Mortgage Securities Fund - Initial Class
on October 31, 1988. As the chart shows, by October 31, 1998, the
value of the investment would have grown to $22,596 - a 125.96%
increase on the initial investment. For comparison, look at how the
Lehman Brothers Mortgage-Backed Securities Index did over the same
period. With dividends and capital gains, if any, reinvested, the same
$10,000 would have grown to $23,261 - a 132.61% increase.

FUND TALK: THE MANAGER'S OVERVIEW
 
 
 
MARKET RECAP
Uncertainty in the global equity 
markets, combined with two 
interest-rate cuts by the Federal 
Reserve Board, provided the 
backdrop for strong gains in the 
bond market during the 12-month 
period ended October 31, 1998. The 
Lehman Brothers Aggregate Bond 
Index - a broad measure of the U.S. 
taxable investment-grade bond 
market - returned 9.34% over the 
past year. Global market volatility, 
low interest rates and a sharp 
decline in stock prices sent U.S. 
Treasury yields - which move in the 
opposite direction of bond prices - 
to their lowest levels in 30 years. 
While the extreme flight to quality 
helped Treasuries outperform all 
other sectors of the bond market, 
corporate bond investors benefited 
from a stable domestic economy, 
low interest rates and low inflation. 
The Lehman Brothers Corporate 
Bond Index returned 7.99% for the 
past 12 months. Despite high 
refinancing activity, mortgage bonds 
also performed well. The Lehman 
Brothers Mortgage-Backed Securities 
Index posted a 12-month return of 
7.30%. Late in the period, the bond 
market stumbled as the Group of 
Seven leading industrial nations 
eased global market fears with 
announcements that the International 
Monetary Fund would establish a 
precautionary line of credit to help 
certain countries resolve their 
financial crises. In spite of weakness 
toward the end of the period, the 
yield on the benchmark 30-year 
Treasury closed at 5.15%.
An interview with Tom Silvia, Portfolio Manager of Fidelity Advisor
Mortgage Securities Fund
Q. HOW DID THE FUND PERFORM, TOM?
A. For the 12 months that ended October 31, 1998, the fund's Initial
Class shares returned 5.99%. During the same period, the U.S. mortgage
funds average, according to Lipper Analytical Services, returned
6.62%, and the Lehman Brothers Mortgage-Backed Securities Index
returned 7.30%. 
Q. HOW WOULD YOU CHARACTERIZE THE MORTGAGE MARKET OVER THE PAST 12
MONTHS?
A. During the first six months of the period, the mortgage market was
surprisingly strong. Low inflation and enormous foreign demand for
U.S. government securities in the wake of the Asian economic crisis
bid Treasury prices up, pushing the 10-year yield down to 5.35% early
in 1998. Falling interest rates usually cause mortgage prices to lag
Treasuries because of increased prepayment risk. As interest rates
fall, many borrowers refinance their home loans, returning the
principal to investors who may have to reinvest at lower rates.
Despite these conditions, investors were attracted by the relatively
high yields offered by mortgage securities. However, the mortgage
market changed direction during the second half of the period.
Emerging monetary and political problems in Russia renewed concern
about the unstable conditions in Asia. Bond-market investors became
less tolerant of risk and sold mortgage securities in favor of
higher-quality, more liquid government securities, flooding the market
with mortgage supply. Interest rates fell to historic low levels,
increasing prepayment risk, which further depressed demand for
mortgage securities. Market liquidity declined substantially and
prices stagnated. Yield spreads reached their widest point in over 10
years as investors required significantly higher rates to choose
mortgages over Treasury securities. 
Q. WHAT WAS YOUR INVESTMENT STRATEGY THROUGHOUT THE PERIOD?
A. My overall objective was to limit relative prepayment risk. My
strategy is based on a disciplined process that first evaluates the
Lehman Brothers index, the fund's performance benchmark. Next, I
allocate assets among the agency sectors based on my assessment of
relative value. During the period, I overweighted Ginnie Mae-issued
mortgages, which were experiencing slower prepayment rates relative to
Fannie Mae and Freddie Mac mortgages. In addition, Ginnie Mae loans
are explicitly guaranteed by the U.S. Treasury. Once sector weights
are determined, I select specific securities. For example, as interest
rates fell, I emphasized seasoned mortgages that had weathered several
prepayment cycles, as well as brand-new mortgages issued at lower
rates that I thought would carry less refinancing risk. Finally, I
look at sectors outside of the index, such as non-agency securities,
commercial mortgages, collateralized mortgage obligations and
adjustable-rate mortgages. For much of the year, I had a significant
proportion of the fund's assets invested in commercial mortgage
securities (CMS). The loans underlying CMS usually have prepayment
restrictions built into their structure, so they can help reduce a
fund's prepayment risk when interest rates are falling.
Q. WEREN'T THERE PROBLEMS IN THE COMMERCIAL MORTGAGE SECTOR DURING THE
YEAR?
A. Yes, there were. During the final months of the period, CMS
dramatically underperformed other types of mortgage securities.
Although they have lower prepayment risk, CMS have greater credit
risk. As a result, this sector was hurt when investors shifted their
preference to very liquid, high-quality instruments such as Treasury
securities. In addition, many hedge funds and real estate investment
trusts had borrowed heavily to purchase relatively high-yielding
securities such as CMS. However, as global credit concerns caused the
CMS sector to weaken, these investors were left holding billions of
dollars of securities that could only be sold at higher yields. Forced
selling of this sector to cover loans reduced liquidity, and prices
fell further. Because the fund was overweighted in commercial
mortgages relative to its benchmark and its peers, CMS were the
largest contributor to the fund's disappointing 12-month total return.
Q. DID YOU REDUCE YOUR CMS EXPOSURE?
A. No, I didn't. I believe that the CMS sector has been oversold. I
haven't seen any fundamental reason to withdraw from this market.
Furthermore, this sector continues to offer good protection against
prepayment risk, which is my primary investment strategy. 
Q. WHAT'S YOUR OUTLOOK FOR THE COMING MONTHS? 
A. I am taking a cautious approach to the market. As long as interest
rates have the possibility to fall further, prepayment risk will
continue to limit mortgage securities performance. I plan to emphasize
the fund's defensive characteristics until there are conclusive
changes in the economy's direction.

ON MARKET AND OTHER CONDITIONS.
 
TOM SILVIA ON COMMERCIAL 
MORTGAGE SECURITIES (CMS):
"The CMS market has been among 
the fastest growing sectors of the 
fixed-income market. CMS are bonds 
that are collateralized by mortgage 
loans on commercial real estate 
such as office buildings, shopping 
malls, hotels and apartment 
buildings. This market sector was 
created in the mid 1980s, and 
today the amount of commercial 
mortgage loans outstanding in the 
United States is approximately $1.5 
trillion. 
"Commercial mortgages differ from 
the mortgage securities comprising 
the fund's performance benchmark, 
the Lehman Brothers 
Mortgage-Backed Securities 
Index. The index is made up of 
single-family home mortgages 
issued by one of three housing 
agencies - Ginnie Mae (GNMA), 
Fannie Mae (FNMA) and Freddie 
Mac (FHLMC). Agency mortgage 
securities have minimal credit risk 
and carry an implied triple-A 
rating because of their relationship 
with the U.S. Treasury. GNMA 
securities are guaranteed by the 
government, while FNMA and 
FHLMC securities carry an implied 
guarantee. CMS are privately 
issued and are not supported by the 
government. The primary advantage 
of investing in commercial versus 
agency single-family mortgages is 
related to prepayment risk. 
Commercial mortgages typically 
have some form of prepayment 
protection because commercial 
borrowers are usually restricted 
from early loan payoffs. Thus, CMS 
provide an efficient way to reduce 
a portfolio's prepayment risk, 
particularly in periods when 
interest rates are falling."

1. SIGNIFICANT ACCOUNTING POLICIES.
Fidelity Advisor Mortgage Securities Fund (the fund) is a fund of
Fidelity Income Fund (the trust) and is authorized to issue an
unlimited number of shares. The trust is registered under the
Investment Company Act of 1940, as amended (the 1940 Act), as an
open-end management investment company organized as a Massachusetts
business trust.
The fund offers Class A, Class T, Class B, Initial Class, and
Institutional Class shares, each of which has equal rights as to
assets and voting privileges. Each class has exclusive voting rights
with respect to matters that affect that class. Class B shares will
automatically convert to Class A shares after a holding period of
seven years from the initial date of purchase. Interest income,
realized and unrealized capital gains and losses, the common expenses
of the fund, and certain fund-level expense reductions, if any, are
allocated on a pro rata basis to each class based on the relative net
assets of each class to the total net assets of the fund. Each class
of shares differs in its respective distribution, transfer agent, and
certain other class-specific fees, expenses, and expense reductions.
The financial statements have been prepared in conformity with
generally accepted accounting principles which require management to
make certain estimates and assumptions at the date of the financial
statements. The following summarizes the significant accounting
policies of the fund:
SECURITY VALUATION. Securities are valued based upon a computerized
matrix system and/or appraisals by a pricing service, both of which
consider market transactions and dealer-supplied valuations.
Securities (including restricted securities) for which quotations are
not readily available are valued primarily using dealer-supplied
valuations or at their fair value as determined in good faith under
consistently applied procedures under the general supervision of the
Board of Trustees. Short-term securities with remaining maturities of
sixty days or less for which quotations are not readily available are
valued at amortized cost or original cost plus accrued interest, both
of which approximate current value.
INCOME TAXES. As a qualified regulated investment company under
Subchapter M of the Internal Revenue Code, the fund is not subject to
income taxes to the extent that it distributes substantially all of
its taxable income for its fiscal year. The schedule of investments
includes information regarding income taxes under the caption "Income
Tax Information."
INVESTMENT INCOME. Interest income, which includes accretion of
original issue discount, is accrued as earned.
EXPENSES. Most expenses of the trust can be directly attributed to a
fund. Expenses which cannot be directly attributed are apportioned
among the funds in the trust.
DISTRIBUTIONS TO SHAREHOLDERS. Distributions are declared daily and
paid monthly from net investment income. Distributions from realized
gains, if any, are recorded on 
1. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED
DISTRIBUTIONS TO SHAREHOLDERS - CONTINUED
the ex-dividend date. Income dividends and capital gain distributions
are declared separately for each class.
Income and capital gain distributions are determined in accordance
with income tax regulations which may differ from generally accepted
accounting principles. These differences, which may result in
distribution reclassifications, are primarily due to differing
treatments for paydown gains/losses on certain securities, futures
transactions and losses deferred due to wash sales. The fund also
utilized earnings and profits distributed to shareholders on
redemption of shares as a part of the dividends paid deduction for
income tax purposes.
Permanent book and tax basis differences relating to shareholder
distributions will result in reclassifications to paid in capital.
Undistributed net investment income and accumulated undistributed net
realized gain (loss) on investments may include temporary book and tax
basis differences which will reverse in a subsequent period. Any
taxable income or gain remaining at fiscal year end is distributed in
the following year.
SECURITY TRANSACTIONS. Security transactions are accounted for as of
trade date. Gains and losses on securities sold are determined on the
basis of identified cost.
2. OPERATING POLICIES.
JOINT TRADING ACCOUNT. Pursuant to an Exemptive Order issued by the
Securities and Exchange Commission, the fund, along with other
affiliated entities of Fidelity Management & Research Company (FMR),
may transfer uninvested cash balances into one or more joint trading
accounts. These balances are invested in one or more repurchase
agreements for U.S. Treasury or Federal Agency obligations.
REPURCHASE AGREEMENTS. The underlying U.S. Treasury or Federal Agency
securities are transferred to an account of the fund, or to the Joint
Trading Account, at a bank custodian. The securities are
marked-to-market daily and maintained at a value at least equal to the
principal amount of the repurchase agreement (including accrued
interest). FMR, the fund's investment adviser, is responsible for
determining that the value of the underlying securities remains in
accordance with the market value requirements stated above. 
DELAYED DELIVERY TRANSACTIONS. The fund may purchase or sell
securities on a delayed delivery basis. Payment and delivery may take
place a month or more after the date of the transaction. The price of
the underlying securities and the date when the securities will be
delivered and paid for are fixed at the time the transaction is
negotiated. The market values of the securities purchased or sold on a
delayed delivery basis are identified as such in the fund's schedule
of investments. The fund may receive 
2. OPERATING POLICIES - CONTINUED
DELAYED DELIVERY TRANSACTIONS - CONTINUED
compensation for interest forgone in the purchase of a delayed
delivery security. With respect to purchase commitments, the fund
identifies securities as segregated in its custodial records with a
value at least equal to the amount of the commitment. Losses may arise
due to changes in the market value of the underlying securities or if
the counterparty does not perform under the contract. 
FUTURES CONTRACTS. The fund may use futures contracts to manage its
exposure to the bond market and to fluctuations in interest rates.
Buying futures tends to increase the fund's exposure to the underlying
instrument, while selling futures tends to decrease the fund's
exposure to the underlying instrument or hedge other fund investments.
Futures contracts involve, to varying degrees, risk of loss in excess
of the futures variation margin reflected in the Statement of Assets
and Liabilities. The underlying face amount at value of any open
futures contracts at period end is shown in the schedule of
investments under the caption "Futures Contracts." This amount
reflects each contract's exposure to the underlying instrument at
period end. Losses may arise from changes in the value of the
underlying instruments or if the counterparties do not perform under
the contracts' terms. Gains (losses) are realized upon the expiration
or closing of the futures contracts. Futures contracts are valued at
the settlement price established each day by the board of trade or
exchange on which they are traded.
RESTRICTED SECURITIES. The fund is permitted to invest in securities
that are subject to legal or contractual restrictions on resale. These
securities generally may be resold in transactions exempt from
registration or to the public if the securities are registered.
Disposal of these securities may involve time-consuming negotiations
and expense, and prompt sale at an acceptable price may be difficult.
At the end of the period, the fund had no investments in restricted
securities (excluding 144A issues).
3. PURCHASES AND SALES OF INVESTMENTS. 
Purchases and sales of long-term U.S. government and government agency
obligations aggregated $1,299,705,940 and $1,306,435,411,
respectively.
The market value of futures contracts opened and closed during the
period amounted to $10,201,804 and $0, respectively.
4. FEES AND OTHER TRANSACTIONS WITH AFFILIATES. 
MANAGEMENT FEE. As the fund's investment adviser, FMR receives a
monthly fee that is calculated on the basis of a group fee rate plus a
fixed individual fund fee rate applied to the average net assets of
the fund. The group fee rate is the weighted average of a series of
rates and is based on the monthly average net assets of all the mutual
funds advised by FMR. 
4. FEES AND OTHER TRANSACTIONS WITH AFFILIATES - CONTINUED
MANAGEMENT FEE - CONTINUED
The rates ranged from .1100% to .3700% for the period. The annual
individual fund fee rate is .30%. In the event that these rates were
lower than the contractual rates in effect during the period, FMR
voluntarily implemented the above rates, as they resulted in the same
or a lower management fee. For the period, the management fee was
equivalent to an annual rate of .44% of average net assets.
DISTRIBUTION AND SERVICE PLAN. In accordance with Rule 12b-1 of the
1940 Act, the Trustees have adopted separate distribution plans with
respect to each class of shares (collectively referred to as "the
Plans"). Under certain of the Plans, the class pays Fidelity
Distributors Corporation (FDC), an affiliate of FMR, a distribution
and service fee. A portion of this fee may be reallowed to securities
dealers, banks and other financial institutions for the distribution
of each class of shares and providing shareholder support services.
For the period, this fee was based on the following annual rates of
the average net assets of each applicable class:
 
CLASS A    .15%   
 
CLASS T    .25%   
 
CLASS B    .90%*  
 
* .65% REPRESENTS A DISTRIBUTION FEE AND .25% REPRESENTS A SHAREHOLDER
SERVICE FEE.
For the period, each class paid FDC the following amounts, a portion
of which was retained by FDC:
 
          PAID TO   RETAINED  
          FDC       BY FDC    
 
CLASS A   $ 1,249   $ 189     
 
CLASS T    36,423    13,984   
 
CLASS B    35,531    25,811   
 
          $ 73,203  $ 39,984  
 
Under the Plans, FMR may use its resources to pay administrative and
promotional expenses related to the sale of each class' shares. The
Plans also authorize payments to third parties that assist in the sale
of each class' shares or render shareholder support services. For the
period, the following amounts were paid to third parties under the
Plans: 
 
CLASS A               $ 107   
 
CLASS T                6,184  
 
CLASS B                415    
 
INSTITUTIONAL CLASS    2,793  
 
4. FEES AND OTHER TRANSACTIONS WITH AFFILIATES - CONTINUED
SALES LOAD. FDC receives a front-end sales charge of up to 4.75% for
selling Class A shares, and 3.50% for selling Class T shares of the
fund. FDC receives the proceeds of contingent deferred sales charges
levied on Class B share redemptions occurring within six years of
purchase. The Class B charge is based on declining rates ranging from
5% to 1% of the lesser of the cost of shares at the initial date of
purchase or the net asset value of the redeemed shares, excluding any
reinvested dividends and capital gains. In addition, purchases of
Class A and Class T shares that were subject to a finder's fee bear a
contingent deferred sales charge on assets that do not remain in the
fund for at least one year. The Class A and Class T contingent
deferred sales charge is based on 0.25% of the lesser of the cost of
shares at the initial date of purchase or the net asset value of the
redeemed shares, excluding any reinvested dividends and capital gains.
A portion of the sales charges paid to FDC are paid to securities
dealers, banks and other financial institutions.
For the period, sales charge amounts paid to and retained by FDC were
as follows:
 
          PAID TO   RETAINED  
          FDC       BY FDC    
 
CLASS A   $ 15,729  $ 5,230   
 
CLASS T    32,042    9,363    
 
CLASS B    7,660     7,660 *  
 
          $ 55,431  $ 22,253  
 
* WHEN CLASS B SHARES ARE INITIALLY SOLD, FDC PAYS COMMISSIONS FROM
ITS OWN RESOURCES TO SECURITIES DEALERS,
 BANKS, AND OTHER FINANCIAL INSTITUTIONS THROUGH WHICH THE SALES ARE
MADE.
TRANSFER AGENT FEES. Fidelity Investments Institutional Operations
Company, Inc., (FIIOC), an affiliate of FMR, is the transfer, dividend
disbursing and shareholder servicing agent (collectively referred to
as the transfer agent) for the fund's Class A, Class T, Class B, and
Institutional Class. Fidelity Service Company, Inc. (FSC), an
affiliate of FMR, is the transfer agent for the Initial Class. FIIOC
and FSC pay for typesetting, printing and mailing of all shareholder
reports, except proxy statements. For the period, the following

In addition, the fund has entered into an arrangement with its
custodian whereby credits realized as a result of uninvested cash
balances were used to reduce a portion of expenses. During the period,
the fund's custodian fees were reduced by $6,166 under the custodian
arrangement.

REPORT OF INDEPENDENT ACCOUNTANTS
 
 
To the Trustees of Fidelity Income Fund and the Shareholders of
Fidelity Advisor Mortgage Securities Fund:
In our opinion, the accompanying statement of assets and liabilities,
including the schedule of investments, and the related statements of
operations and of changes in net assets and the financial highlights
present fairly, in all material respects, the financial position of
Fidelity Advisor Mortgage Securities Fund (a fund of Fidelity Income
Fund) at October 31, 1998, the results of its operations, the changes
in its net assets and the financial highlights for the periods
indicated, in conformity with generally accepted accounting
principles. These financial statements and financial highlights
(hereafter referred to as "financial statements") are the
responsibility of  Fidelity Advisor Mortgage Securities Fund 's
management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of
these financial statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are
free of material misstatement. An audit includes examining, on a test
basis, evidence supporting the amounts and disclosures in the
financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which
included confirmation of securities at October 31, 1998 by
correspondence with the custodian and brokers, provide a reasonable
basis for the opinion expressed above.

PRESIDENT'S MESSAGE
 
 
(PHOTO_OF_EDWARD_C_JOHNSON_3D)DEAR SHAREHOLDER:
What a difference one month can make. The stock and bond markets did
an about-face in October, as renewed optimism in many emerging markets
and more encouraging corporate earnings forecasts in the U.S. replaced
the concerns that had shaped the financial markets in recent months.
Equity markets worldwide bounced back strongly, while the major U.S.
bond indexes were off slightly as the flight to safety eased. 
While it's impossible to predict the future direction of the markets
with any degree of certainty, there are certain basic principles that
can help investors plan for their future needs.
The longer your investment time frame, the less likely it is that you
will be affected by short-term market volatility. A 10-year investment
horizon appropriate for saving for a college education, for example,
enables you to weather market cycles in a long-term fund, which may
have a higher risk potential, but also has a higher potential rate of
return.
An intermediate-length fund could make sense if your investment
horizon is two to four years, while a short-term bond fund could be
the right choice if you need your money in one or two years.
If your time horizon is less than a year, you might want to consider
moving some of your bond investment into a money market fund. These
funds seek income and a stable share price by investing in
high-quality, short-term investments. Of course, it's important to
remember that there is no assurance that a money market fund will
achieve its goal of maintaining a stable net asset value of $1.00 per
share, and that these types of funds are neither insured nor
guaranteed by any agency of the U.S. government.
Finally, no matter what your time horizon or portfolio diversity, it
makes good sense to follow a regular investment plan, investing a
certain amount of money in a fund at the same time each month or
quarter and periodically reviewing your overall portfolio. By doing
so, you won't get caught up in the excitement of a rapidly rising
market, nor will you buy all your shares at market highs. While this
strategy - known as dollar cost averaging - won't assure a profit or
protect you from a loss in a declining market, it should help you
lower the average cost of your purchases. Of course, you should
consider your financial ability to continue your purchases through
periods of low price levels before undertaking such a strategy.
Remember to contact your investment professional if you need help with
your investments.
Best regards,
Edward C. Johnson 3d
 
FIDELITY ADVISOR MORTGAGE SECURITIES FUND - INSTITUTIONAL CLASS
PERFORMANCE: THE BOTTOM LINE
 
 
There are several ways to evaluate historical performance. You can
look at the total percentage change in value, the average annual
percentage change or the growth of a hypothetical $10,000 investment.
Total return reflects the change in the value of an investment,
assuming reinvestment of the class' dividend income and capital gains
(the profits earned upon the sale of securities that have grown in
value). You can also look at the class' income, as reflected in its
yield, to measure performance. The initial offering of Institutional
Class shares took place on March 3, 1997. Returns prior to March 3,
1997 are those of Initial Class, the original class of the fund. If
Fidelity had not reimbursed certain class expenses, the total returns
and dividends would have been lower.
 
CUMULATIVE TOTAL RETURNS

                                                 YEAR    YEARS   YEARS    
 
FIDELITY ADV MORTGAGE SECURITIES - INST CL       5.86%   44.49%  125.47%

US MORTGAGE FUNDS AVERAGE                        6.62%   32.38%  111.59%  
 
CUMULATIVE TOTAL RETURNS show Institutional Class' performance in
percentage terms over a set period - in this case, one year, five
years or 10 years. For example, if you had invested $1,000 in a fund
that had a 5% return over the past year, the value of your investment
would be $1,050. You can compare Institutional Class' returns to the
performance of the Lehman Brothers Mortgage-Backed Securities Index -
a market capitalization weighted index of 15- and 30-year fixed-rate
securities backed by mortgage pools of the Ginnie Mae (GNMA), Fannie
Mae (FNMA) and Freddie Mac (FHLMC), and FNMA and FHLMC balloon
mortgages with fixed-rate coupons. To measure how Institutional Class'
performance stacked up against its peers, you can compare it to the
U.S. mortgage funds average, which reflects the performance of mutual
funds with similar objectives tracked by Lipper Analytical Services,
Inc. The past one year average represents a peer group of 68 mutual
funds. These benchmarks reflect reinvestment of dividends and capital
gains, if any, and exclude the effect of sales charges.

$10,000 OVER 10 YEARS: Let's say hypothetically that $10,000 was
invested in Fidelity Advisor Mortgage Securities Fund - Institutional
Class on October 31, 1988. As the chart shows, by October 31, 1998,
the value of the investment would have grown to $22,547 - a 125.47%
increase on the initial investment. For comparison, look at how the
Lehman Brothers Mortgage-Backed Securities Index did over the same
period. With dividends and capital gains, if any, reinvested, the same
$10,000 would have grown to $23,261 - a 132.61% increase.
 
UNDERSTANDING
PERFORMANCE
HOW A FUND DID YESTERDAY IS 
NO GUARANTEE OF HOW IT WILL DO 
TOMORROW. BOND PRICES, FOR 
EXAMPLE, GENERALLY MOVE IN THE 
OPPOSITE DIRECTION OF INTEREST 
RATES. IN TURN, THE SHARE PRICE, 
RETURN AND YIELD OF A FUND THAT 
INVESTS IN BONDS WILL VARY. THAT 
MEANS IF YOU SELL YOUR SHARES 
DURING A MARKET DOWNTURN, YOU 
MIGHT LOSE MONEY. BUT IF YOU CAN 
RIDE OUT THE MARKET'S UPS AND 
DOWNS, YOU MAY HAVE A GAIN.

returns. A dividend return reflects the actual dividends paid by the
class. A capital return reflects both the amount paid by the class to
shareholders as capital gain distributions and changes in the class'
share price. Both returns assume the dividends or capital gains paid
by the class are reinvested, if any.

DIVIDENDS per share show the income paid by the class for a set
period. If you annualize this number, based on an average share price
of $11.02 over the past one month, $11.03 over the past six months,
and $11.02 over the past one year, you can compare the class' income
over these three periods. The 30-day annualized YIELD is a standard
formula for all funds based on the yields of the bonds in the fund,
averaged over the past 30 days. This figure shows you the yield
characteristics of the fund's investments at the end of the period. It
also helps you compare funds from different companies on an equal

FUND TALK: THE MANAGER'S OVERVIEW
 
 
 
MARKET RECAP
Uncertainty in the global equity 
markets, combined with two 
interest-rate cuts by the Federal 
Reserve Board, provided the 
backdrop for strong gains in the 
bond market during the 12-month 
period ended October 31, 1998. The 
Lehman Brothers Aggregate Bond 
Index - a broad measure of the U.S. 
taxable investment-grade bond 
market - returned 9.34% over the 
past year. Global market volatility, 
low interest rates and a sharp 
decline in stock prices sent U.S. 
Treasury yields - which move in the 
opposite direction of bond prices - 
to their lowest levels in 30 years. 
While the extreme flight to quality 
helped Treasuries outperform all 
other sectors of the bond market, 
corporate bond investors benefited 
from a stable domestic economy, 
low interest rates and low inflation. 
The Lehman Brothers Corporate 
Bond Index returned 7.99% for the 
past 12 months. Despite high 
refinancing activity, mortgage bonds 
also performed well. The Lehman 
Brothers Mortgage-Backed Securities 
Index posted a 12-month return of 
7.30%. Late in the period, the bond 
market stumbled as the Group of 
Seven leading industrial nations 
eased global market fears with 
announcements that the International 
Monetary Fund would establish a 
precautionary line of credit to help 
certain countries resolve their 
financial crises. In spite of weakness 
toward the end of the period, the 
yield on the benchmark 30-year 
Treasury closed at 5.15%.
An interview with Tom Silvia, Portfolio Manager of Fidelity Advisor
Mortgage Securities Fund
Q. HOW DID THE FUND PERFORM, TOM?
A. For the 12 months that ended October 31, 1998, the fund's
Institutional Class shares returned 5.86%. During the same period, the
U.S. mortgage funds average, according to Lipper Analytical Services,
returned 6.62%, and the Lehman Brothers Mortgage-Backed Securities
Index returned 7.30%.
Q. HOW WOULD YOU CHARACTERIZE THE MORTGAGE MARKET OVER THE PAST 12
MONTHS?
A. During the first six months of the period, the mortgage market was
surprisingly strong. Low inflation and enormous foreign demand for
U.S. government securities in the wake of the Asian economic crisis
bid Treasury prices up, pushing the 10-year yield down to 5.35% early
in 1998. Falling interest rates usually cause mortgage prices to lag
Treasuries because of increased prepayment risk. As interest rates
fall, many borrowers refinance their home loans, returning the
principal to investors who may have to reinvest at lower rates.
Despite these conditions, investors were attracted by the relatively
high yields offered by mortgage securities. However, the mortgage
market changed direction during the second half of the period.
Emerging monetary and political problems in Russia renewed concern
about the unstable conditions in Asia. Bond-market investors became
less tolerant of risk and sold mortgage securities in favor of
higher-quality, more liquid government securities, flooding the market
with mortgage supply. Interest rates fell to historic low levels,
increasing prepayment risk, which further depressed demand for
mortgage securities. Market liquidity declined substantially and
prices stagnated. Yield spreads reached their widest point in over 10
years as investors required significantly higher rates to choose
mortgages over Treasury securities. 
Q. WHAT WAS YOUR INVESTMENT STRATEGY THROUGHOUT THE PERIOD?
A. My overall objective was to limit relative prepayment risk. My
strategy is based on a disciplined process that first evaluates the
Lehman Brothers index, the fund's performance benchmark. Next, I
allocate assets among the agency sectors based on my assessment of
relative value. During the period, I overweighted Ginnie Mae-issued
mortgages, which were experiencing slower prepayment rates relative to
Fannie Mae and Freddie Mac mortgages. In addition, Ginnie Mae loans
are explicitly guaranteed by the U.S. Treasury. Once sector weights
are determined, I select specific securities. For example, as interest
rates fell, I emphasized seasoned mortgages that had weathered several
prepayment cycles, as well as brand-new mortgages issued at lower
rates that I thought would carry less refinancing risk. Finally, I
look at sectors outside of the index, such as non-agency securities,
commercial mortgages, collateralized mortgage obligations and
adjustable-rate mortgages. For much of the year, I had a significant
proportion of the fund's assets invested in commercial mortgage
securities (CMS). The loans underlying CMS usually have prepayment
restrictions built into their structure, so they can help reduce a
fund's prepayment risk when interest rates are falling.
Q. WEREN'T THERE PROBLEMS IN THE COMMERCIAL MORTGAGE SECTOR DURING THE
YEAR?
A. Yes, there were. During the final months of the period, CMS
dramatically underperformed other types of mortgage securities.
Although they have lower prepayment risk, CMS have greater credit
risk. As a result, this sector was hurt when investors shifted their
preference to very liquid, high-quality instruments such as Treasury
securities. In addition, many hedge funds and real estate investment
trusts had borrowed heavily to purchase relatively high-yielding
securities such as CMS. However, as global credit concerns caused the
CMS sector to weaken, these investors were left holding billions of
dollars of securities that could only be sold at higher yields. Forced
selling of this sector to cover loans reduced liquidity, and prices
fell further. Because the fund was overweighted in commercial
mortgages relative to its benchmark and its peers, CMS were the
largest contributor to the fund's disappointing 12-month total return.
Q. DID YOU REDUCE YOUR CMS EXPOSURE?
A. No, I didn't. I believe that the CMS sector has been oversold. I
haven't seen any fundamental reason to withdraw from this market.
Furthermore, this sector continues to offer good protection against
prepayment risk, which is my primary investment strategy. 
Q. WHAT'S YOUR OUTLOOK FOR THE COMING MONTHS? 
A. I am taking a cautious approach to the market. As long as interest
rates have the possibility to fall further, prepayment risk will
continue to limit mortgage securities performance. I plan to emphasize
the fund's defensive characteristics until there are conclusive
changes in the economy's direction.

TOM SILVIA ON COMMERCIAL 
MORTGAGE SECURITIES (CMS):
"The CMS market has been among 
the fastest growing sectors of the 
fixed-income market. CMS are bonds 
that are collateralized by mortgage 
loans on commercial real estate 
such as office buildings, shopping 
malls, hotels and apartment 
buildings. This market sector was 
created in the mid 1980s, and 
today the amount of commercial 
mortgage loans outstanding in the 
United States is approximately $1.5 
trillion. 
"Commercial mortgages differ from 
the mortgage securities comprising 
the fund's performance benchmark, 
the Lehman Brothers 
Mortgage-Backed Securities 
Index. The index is made up of 
single-family home mortgages 
issued by one of three housing 
agencies - Ginnie Mae (GNMA), 
Fannie Mae (FNMA) and Freddie 
Mac (FHLMC). Agency mortgage 
securities have minimal credit risk 
and carry an implied triple-A 
rating because of their relationship 
with the U.S. Treasury. GNMA 
securities are guaranteed by the 
government, while FNMA and 
FHLMC securities carry an implied 
guarantee. CMS are privately 
issued and are not supported by the 
government. The primary advantage 
of investing in commercial versus 
agency single-family mortgages is 
related to prepayment risk. 
Commercial mortgages typically 
have some form of prepayment 
protection because commercial 
borrowers are usually restricted 
from early loan payoffs. Thus, CMS 
provide an efficient way to reduce 
a portfolio's prepayment risk, 
particularly in periods when 
interest rates are falling."

1. SIGNIFICANT ACCOUNTING POLICIES.
Fidelity Advisor Mortgage Securities Fund (the fund) is a fund of
Fidelity Income Fund (the trust) and is authorized to issue an
unlimited number of shares. The trust is registered under the
Investment Company Act of 1940, as amended (the 1940 Act), as an
open-end management investment company organized as a Massachusetts
business trust.
The fund offers Class A, Class T, Class B, Initial Class, and
Institutional Class shares, each of which has equal rights as to
assets and voting privileges. Each class has exclusive voting rights
with respect to matters that affect that class. Class B shares will
automatically convert to Class A shares after a holding period of
seven years from the initial date of purchase. Interest income,
realized and unrealized capital gains and losses, the common expenses
of the fund, and certain fund-level expense reductions, if any, are
allocated on a pro rata basis to each class based on the relative net
assets of each class to the total net assets of the fund. Each class
of shares differs in its respective distribution, transfer agent, and
certain other class-specific fees, expenses, and expense reductions.
The financial statements have been prepared in conformity with
generally accepted accounting principles which require management to
make certain estimates and assumptions at the date of the financial
statements. The following summarizes the significant accounting
policies of the fund:
SECURITY VALUATION. Securities are valued based upon a computerized
matrix system and/or appraisals by a pricing service, both of which
consider market transactions and dealer-supplied valuations.
Securities (including restricted securities) for which quotations are
not readily available are valued primarily using dealer-supplied
valuations or at their fair value as determined in good faith under
consistently applied procedures under the general supervision of the
Board of Trustees. Short-term securities with remaining maturities of
sixty days or less for which quotations are not readily available are
valued at amortized cost or original cost plus accrued interest, both
of which approximate current value.
INCOME TAXES. As a qualified regulated investment company under
Subchapter M of the Internal Revenue Code, the fund is not subject to
income taxes to the extent that it distributes substantially all of
its taxable income for its fiscal year. The schedule of investments
includes information regarding income taxes under the caption "Income
Tax Information."
INVESTMENT INCOME. Interest income, which includes accretion of
original issue discount, is accrued as earned.
EXPENSES. Most expenses of the trust can be directly attributed to a
fund. Expenses which cannot be directly attributed are apportioned
among the funds in the trust.
DISTRIBUTIONS TO SHAREHOLDERS. Distributions are declared daily and
paid monthly from net investment income. Distributions from realized
gains, if any, are recorded on 
1. SIGNIFICANT ACCOUNTING POLICIES - CONTINUED
DISTRIBUTIONS TO SHAREHOLDERS - CONTINUED
the ex-dividend date. Income dividends and capital gain distributions
are declared separately for each class.
Income and capital gain distributions are determined in accordance
with income tax regulations which may differ from generally accepted
accounting principles. These differences, which may result in
distribution reclassifications, are primarily due to differing
treatments for paydown gains/losses on certain securities, futures
transactions and losses deferred due to wash sales. The fund also
utilized earnings and profits distributed to shareholders on
redemption of shares as a part of the dividends paid deduction for
income tax purposes.
Permanent book and tax basis differences relating to shareholder
distributions will result in reclassifications to paid in capital.
Undistributed net investment income and accumulated undistributed net
realized gain (loss) on investments may include temporary book and tax
basis differences which will reverse in a subsequent period. Any
taxable income or gain remaining at fiscal year end is distributed in
the following year.
SECURITY TRANSACTIONS. Security transactions are accounted for as of
trade date. Gains and losses on securities sold are determined on the
basis of identified cost.
2. OPERATING POLICIES.
JOINT TRADING ACCOUNT. Pursuant to an Exemptive Order issued by the
Securities and Exchange Commission, the fund, along with other
affiliated entities of Fidelity Management & Research Company (FMR),
may transfer uninvested cash balances into one or more joint trading
accounts. These balances are invested in one or more repurchase
agreements for U.S. Treasury or Federal Agency obligations.
REPURCHASE AGREEMENTS. The underlying U.S. Treasury or Federal Agency
securities are transferred to an account of the fund, or to the Joint
Trading Account, at a bank custodian. The securities are
marked-to-market daily and maintained at a value at least equal to the
principal amount of the repurchase agreement (including accrued
interest). FMR, the fund's investment adviser, is responsible for
determining that the value of the underlying securities remains in
accordance with the market value requirements stated above. 
DELAYED DELIVERY TRANSACTIONS. The fund may purchase or sell
securities on a delayed delivery basis. Payment and delivery may take
place a month or more after the date of the transaction. The price of
the underlying securities and the date when the securities will be
delivered and paid for are fixed at the time the transaction is
negotiated. The market values of the securities purchased or sold on a
delayed delivery basis are identified as such in the fund's schedule
of investments. The fund may receive

DELAYED DELIVERY TRANSACTIONS - CONTINUED
compensation for interest forgone in the purchase of a delayed
delivery security. With respect to purchase commitments, the fund
identifies securities as segregated in its custodial records with a
value at least equal to the amount of the commitment. Losses may arise
due to changes in the market value of the underlying securities or if
the counterparty does not perform under the contract. 
FUTURES CONTRACTS. The fund may use futures contracts to manage its
exposure to the bond market and to fluctuations in interest rates.
Buying futures tends to increase the fund's exposure to the underlying
instrument, while selling futures tends to decrease the fund's
exposure to the underlying instrument or hedge other fund investments.
Futures contracts involve, to varying degrees, risk of loss in excess
of the futures variation margin reflected in the Statement of Assets
and Liabilities. The underlying face amount at value of any open
futures contracts at period end is shown in the schedule of
investments under the caption "Futures Contracts." This amount
reflects each contract's exposure to the underlying instrument at
period end. Losses may arise from changes in the value of the
underlying instruments or if the counterparties do not perform under
the contracts' terms. Gains (losses) are realized upon the expiration
or closing of the futures contracts. Futures contracts are valued at
the settlement price established each day by the board of trade or
exchange on which they are traded.
RESTRICTED SECURITIES. The fund is permitted to invest in securities
that are subject to legal or contractual restrictions on resale. These
securities generally may be resold in transactions exempt from
registration or to the public if the securities are registered.
Disposal of these securities may involve time-consuming negotiations
and expense, and prompt sale at an acceptable price may be difficult.
At the end of the period, the fund had no investments in restricted
securities (excluding 144A issues).
3. PURCHASES AND SALES OF INVESTMENTS. 
Purchases and sales of long-term U.S. government and government agency
obligations aggregated $1,299,705,940 and $1,306,435,411,
respectively.
The market value of futures contracts opened and closed during the
period amounted to $10,201,804 and $0, respectively.
4. FEES AND OTHER TRANSACTIONS WITH AFFILIATES. 
MANAGEMENT FEE. As the fund's investment adviser, FMR receives a
monthly fee that is calculated on the basis of a group fee rate plus a
fixed individual fund fee rate applied to the average net assets of
the fund. The group fee rate is the weighted average of a series of
rates and is based on the monthly average net assets of all the mutual
funds advised by FMR. 
4. FEES AND OTHER TRANSACTIONS WITH AFFILIATES - CONTINUED
MANAGEMENT FEE - CONTINUED
The rates ranged from .1100% to .3700% for the period. The annual
individual fund fee rate is .30%. In the event that these rates were
lower than the contractual rates in effect during the period, FMR
voluntarily implemented the above rates, as they resulted in the same
or a lower management fee. For the period, the management fee was
equivalent to an annual rate of .44% of average net assets.
DISTRIBUTION AND SERVICE PLAN. In accordance with Rule 12b-1 of the
1940 Act, the Trustees have adopted separate distribution plans with
respect to each class of shares (collectively referred to as "the
Plans"). Under certain of the Plans, the class pays Fidelity
Distributors Corporation (FDC), an affiliate of FMR, a distribution
and service fee. A portion of this fee may be reallowed to securities
dealers, banks and other financial institutions for the distribution
of each class of shares and providing shareholder support services.
For the period, this fee was based on the following annual rates of
the average net assets of each applicable class:
 
CLASS A    .15%   
 
CLASS T    .25%   
 
CLASS B    .90%*  
 
* .65% REPRESENTS A DISTRIBUTION FEE AND .25% REPRESENTS A SHAREHOLDER
SERVICE FEE.
For the period, each class paid FDC the following amounts, a portion
of which was retained by FDC:
 
          PAID TO   RETAINED  
          FDC       BY FDC    
 
CLASS A   $ 1,249   $ 189     
 
CLASS T    36,423    13,984   
 
CLASS B    35,531    25,811   
 
          $ 73,203  $ 39,984  
 
Under the Plans, FMR may use its resources to pay administrative and
promotional expenses related to the sale of each class' shares. The
Plans also authorize payments to third parties that assist in the sale
of each class' shares or render shareholder support services. For the
period, the following amounts were paid to third parties under the
Plans: 
 
CLASS A               $ 107   
 
CLASS T                6,184  
 
CLASS B                415    
 
INSTITUTIONAL CLASS    2,793  
 
4. FEES AND OTHER TRANSACTIONS WITH AFFILIATES - CONTINUED
SALES LOAD. FDC receives a front-end sales charge of up to 4.75% for
selling Class A shares, and 3.50% for selling Class T shares of the
fund. FDC receives the proceeds of contingent deferred sales charges
levied on Class B share redemptions occurring within six years of
purchase. The Class B charge is based on declining rates ranging from
5% to 1% of the lesser of the cost of shares at the initial date of
purchase or the net asset value of the redeemed shares, excluding any
reinvested dividends and capital gains. In addition, purchases of
Class A and Class T shares that were subject to a finder's fee bear a
contingent deferred sales charge on assets that do not remain in the
fund for at least one year. The Class A and Class T contingent
deferred sales charge is based on 0.25% of the lesser of the cost of
shares at the initial date of purchase or the net asset value of the
redeemed shares, excluding any reinvested dividends and capital gains.
A portion of the sales charges paid to FDC are paid to securities
dealers, banks and other financial institutions.
For the period, sales charge amounts paid to and retained by FDC were
as follows:
 
          PAID TO   RETAINED  
          FDC       BY FDC    
 
CLASS A   $ 15,729  $ 5,230   
 
CLASS T    32,042    9,363    
 
CLASS B    7,660     7,660 *  
 
          $ 55,431  $ 22,253  
 
* WHEN CLASS B SHARES ARE INITIALLY SOLD, FDC PAYS COMMISSIONS FROM
ITS OWN RESOURCES TO SECURITIES DEALERS,
 BANKS, AND OTHER FINANCIAL INSTITUTIONS THROUGH WHICH THE SALES ARE
MADE.
TRANSFER AGENT FEES. Fidelity Investments Institutional Operations
Company, Inc., (FIIOC), an affiliate of FMR, is the transfer, dividend
disbursing and shareholder servicing agent (collectively referred to
as the transfer agent) for the fund's Class A, Class T, Class B, and
Institutional Class. Fidelity Service Company, Inc. (FSC), an
affiliate of FMR, is the transfer agent for the Initial Class. FIIOC
and FSC pay for typesetting, printing and mailing of all shareholder
reports, except proxy statements. For the period, the following
amounts were paid to FIIOC or FSC:

In addition, the fund has entered into an arrangement with its
custodian whereby credits realized as a result of uninvested cash
balances were used to reduce a portion of expenses. During the period,
the fund's custodian fees were reduced by $6,166 under the custodian
arrangement.

REPORT OF INDEPENDENT ACCOUNTANTS
 
 
To the Trustees of Fidelity Income Fund and the Shareholders of
Fidelity Advisor Mortgage Securities Fund:
In our opinion, the accompanying statement of assets and liabilities,
including the schedule of investments, and the related statements of
operations and of changes in net assets and the financial highlights
present fairly, in all material respects, the financial position of
Fidelity Advisor Mortgage Securities Fund (a fund of Fidelity Income
Fund) at October 31, 1998, the results of its operations, the changes
in its net assets and the financial highlights for the periods
indicated, in conformity with generally accepted accounting
principles. These financial statements and financial highlights
(hereafter referred to as "financial statements") are the
responsibility of  Fidelity Advisor Mortgage Securities Fund 's
management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of
these financial statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are
free of material misstatement. An audit includes examining, on a test
basis, evidence supporting the amounts and disclosures in the
financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which
included confirmation of securities at October 31, 1998 by
correspondence with the custodian and brokers, provide a reasonable
basis for the opinion expressed above.
