Dear Hennessy Advisors Shareholder:                                December 2005

As I draft my fourth letter to shareholders, we continue to experience a
volatile financial market environment, with this fiscal year certainly no
exception. In the past year ending Sept. 30, 2005 we have seen tremendous ups
and downs in a number of key economic areas. The price of oil has skyrocketed
from $42 to $70 a barrel, inflation has nearly doubled from 2.5% to 4.7% and the
Federal Funds interest rate has more than doubled, jumping from 1.75% to 4.0%.
The markets have been rising, but at modest levels, with the S&P 500 Index
returning 12.25% and the Dow Jones Industrial Average returning 7.22% for the
twelve months ending Sept. 30, 2005.

In the midst of this erratic market, during fiscal 2005 Hennessy Advisors
increased assets under management in our mutual funds by nearly 50%, growing to
$1.8 billion on September 30, 2005, compared to $1.2 billion on September 30,
2004. Approximately half of the growth in assets is attributable to the
acquisition of The Henlopen Fund, which occurred in the last quarter of the
fiscal year. With those assets, we started our sixth no-load mutual fund, the
Hennessy Cornerstone Growth Fund, Series II. Revenue for 2005 was just under $12
million, an increase of 25.7%, and net income was $3.1 million, an increase of
13.5% over 2004. Fully diluted earnings per share for Hennessy Advisors, Inc.
were $1.20 in 2005, up from $1.09 in the prior fiscal year, an increase of
10.1%. More investors are beginning to understand and see the value in the
investment advisory business model, which we believe helped to drive our stock
price up by approximately 50% in 2005, ending the fiscal year at $26 per share.
We are very pleased to deliver strong year-over-year results, particularly in
light of the volatile market environment and the increasing regulations and
costs associated with managing our funds.

In addition to increasing assets and earnings, acquiring a fund and starting a
new fund, in 2005 we undertook a number of key initiatives to continue to build
our business foundation. We designed and implemented a rigorous compliance
program for our mutual funds and for Hennessy Advisors. We have significantly
upgraded our information technology, increased our systems security and created
a business continuity plan in case of disaster. We transitioned to a strong new
audit firm and strengthened our internal finance department with the addition of
a new senior accountant. We added additional expertise and depth in our
portfolio management team with the addition of a new portfolio trader. We
combined the fiscal year end of our funds, developed a new combined prospectus
and redesigned the bulk of our marketing materials. And, we recently completed
our move to larger office space. All these activities, which position the
company for future growth, were completed with just ten employees, four of whom
also found time to welcome new additions to their own families during the year.

While interest rates and inflation have increased during the past year, current
interest rates at 4.25% and core inflation (net of food and energy costs) flat
for the year at 2.1% are in no way cause for alarm, in my opinion. Yet the
market bears look at the Fed's interest rate hikes and current economic
indicators and predict doom and gloom. The bears say that the economy is not
showing signs of growth and point to recent events, such as terrorism and the
recent hurricanes, to instill a sense of fear among investors. However, these
events were not able to take the market down.

I continue to be a market bull, seeing generally positive economic indicators
across the board. Companies have become leaner, meaning that any increase in
revenue is falling to the bottom line in the form of higher profits. With
increased earnings, companies are increasing capital expenditures, returning
dividends to the shareholders or buying back stock, all of which benefit
shareholders. In the coming year I see a good environment for business, and I
anticipate an increase in corporate earnings in the 10-15% range, which should
translate to strong market performance over time.

In conclusion, I want to remind all of our shareholders that we remain committed
to our primary objective of growing our assets under management. However, our
first concern is for our valued shareholders, and you can be confident that
decisions are made with your best interest in mind. Thank you for your continued
confidence and investment in Hennessy Advisors. Should you have any questions or
want to speak with us directly, please don't hesitate to call us at (800)
966-4354.

Best regards,

Neil Hennessy
President, Chairman and CEO

                    SHAREHOLDERS TO BE HELD JANUARY 26, 2006



         This proxy statement and the enclosed form of proxy are first being
sent to shareholders of Hennessy Advisors, Inc. on or about December 23, 2005 in
connection with the solicitation by our board of directors of proxies to be used
at our 2006 annual meeting of shareholders. The meeting will be held on
Thursday, January 26, 2006, at 6:30 P.M., local time, at StoneTree Country Club,
9 StoneTree Lane, Novato, California 94945.

         The board of directors has designated Neil J. Hennessy and Teresa M.
Nilsen, and each or either of them, as proxies to vote the shares of common
stock solicited on its behalf. If you sign and return the enclosed form of
proxy, you may nevertheless revoke it at any time insofar as it has not been
exercised by (1) giving written notice to our corporate secretary, (2)
delivering a later dated proxy, or (3) attending the meeting and voting in
person. The shares represented by your proxy will be voted unless the proxy is
mutilated or otherwise received in such form or at such time as to render it not
votable.

                                VOTING SECURITIES

         The record of shareholders entitled to vote was taken at the close of
business on December 9, 2005. At such date, we had outstanding and entitled to
vote 2,462,963 shares of common stock. Each share of common stock entitles the
holder to one vote. Holders of a majority of the outstanding voting stock must
be present in person or represented by proxy to constitute a quorum at the
annual meeting.

         The following table shows information relating to the beneficial
ownership as of the record date of (1) each person known to us to be the
beneficial owner of more than 5% of our voting stock, (2) each director, (3)
each of the executive officers named in the summary compensation table elsewhere
in this proxy statement, and (4) all directors and executive officers as a
group. Except as otherwise indicated, the shareholders listed exercise sole
voting and dispositive power over the shares. All share amounts shown in this
proxy statement have been restated to reflect a 3-for-2 stock split that
occurred on March 8, 2005.

                              ELECTION OF DIRECTORS

         At the meeting, nine directors will be elected to serve for a one-year
term, until their successors are elected and qualified. Prior to August 2005,
when the board elected an additional director in order to fill a newly created
position, the board consisted of eight directors. The board of directors has
nominated each of our nine current directors to stand for reelection. Directors
will be elected by a plurality of votes cast by shares entitled to vote at the
meeting. Broker non-votes and votes withheld have no effect on the outcome.
Cumulative voting does not apply unless a shareholder entitled to vote at the
meeting gives notice before the voting begins of the shareholder's intent to
exercise cumulative voting. If cumulative voting applies, each shareholder has
the right to distribute among one or more nominees the number of votes equal to
the number of directors to be elected multiplied by the number of shares that
the shareholder is entitled to vote at the meeting.

         The accompanying proxy will be voted, if authority to do so is not
withheld, for the election as directors of each of the board's nominees. Each
nominee is presently available for election. If any nominee should become
unavailable, which is not now anticipated, the persons voting the accompanying
proxy may, in their discretion, vote for a substitute.

         Our board of directors recommends a vote "for" the election of each of
its nominees. Proxies solicited by the board will be so voted unless
shareholders specify in their proxies a contrary choice.

         Information concerning all incumbent directors and nominees, based on
data furnished by them, is set forth below.

         Compensation Committee. The compensation committee presently is
composed of Rodger Offenbach (Chairman), Daniel G. Libarle and Thomas L. Seavey,
all of whom are considered independent under Nasdaq rules. The compensation
committee held one meeting during fiscal 2005 to review annual performance. This
committee has the responsibility of approving the compensation arrangements for
our management, including annual bonus and long-term compensation. It also
recommends to the board of directors adoption of any compensation plans in which
our officers and directors are eligible to participate, as well as makes grants
of employee stock options and other stock awards under our incentive plan.

         Audit Committee. The audit committee presently is composed of Daniel G.
Libarle (Chairman), Henry Hansel and Thomas L. Seavey, all of whom are
considered independent under Nasdaq rules. The audit committee met four times
during fiscal 2005. The principal responsibilities of and functions to be
performed by the audit committee are established in the audit committee charter,
a copy of which is attached as Appendix A to this proxy statement. The
responsibilities and functions of the audit committee include reviewing our
internal controls and the integrity of our financial reporting, approving the
employment and compensation of and overseeing our independent auditors, and
reviewing the annual audit with the auditors.

         Our board of directors has determined that Daniel G. Libarle, who has
served as chairman of our audit committee since 2001, is also an audit committee
financial expert, as defined in the SEC rules and regulations, and is
independent as defined by the rules adopted by the SEC and NASDAQ. Our board
based its determination on the fact that Mr. Libarle has extensive experience
evaluating financial statements prepared in accordance with generally accepted
accounting principles and has also acquired an understanding of internal
controls, procedures for financial reporting and audit committee functions as
the founding chairman of the board of Bank of Petaluma since 1985, and as a
member of the audit committee of the board of directors of Greater Bay Bancorp
for the past five years.

         Nominating Committee. The nominating committee is composed of all
directors who qualify as independent under Nasdaq rules, which directors are
presently Charles W. Bennett, Henry Hansel, Daniel G. Libarle, Rodger Offenbach,
and Thomas L. Seavey. The nominating committee was established on September 22,
2005 and did not meet during fiscal 2005. The principal responsibilities of and
functions to be performed by the nominating committee, which includes making
recommendations for director nominees to the full board of directors for the
next annual meeting of shareholders, are established in the nominating committee
charter, which was adopted on September 22, 2005. The nominating committee's
charter is attached as Appendix B to this proxy statement.

Policies and Procedures for Director Nominations

         The nominating committee will consider suggestions for potential
director nominees from many sources, including members of the board, advisors,
and shareholders. Any such nominations, together with appropriate biographical
information, should be submitted to the nominating committee in accordance with
the policies governing submissions of nominees discussed below. Any candidates
submitted by a shareholder or shareholder group will be reviewed and considered
in the same manner as all other candidates.

         Qualifications for consideration as a board nominee may vary according
to the particular areas of expertise being sought as a complement to the
existing board composition. However, in making its nominations, the nominating
committee will consider, among other things, an individual's business
experience, industry experience, financial background, breadth of knowledge
about issues affecting Hennessy, time available for meetings and consultation
regarding Hennessy matters and other particular skills and experience possessed
by the individual. We do not currently employ an executive search firm, or pay a
fee to any other third party, to locate qualified candidates for director
positions, although Hennessy may in the future retain a third party search firm,
if the nominating committee deems it appropriate.

         A shareholder wishing to nominate a candidate for election to our board
at any annual meeting at which one or more directors will be elected must submit
a written notice of his or her nomination of a candidate to our corporate
secretary at our principal executive offices. The submission must be received at
our principal executive offices not more than 180 calendar days nor less than
120 calendar days before the anniversary date of our last annual meeting. For
the 2007 annual meeting, these dates would be July 31, 2006 and September 28,
2006, respectively. To be timely in the case of a special meeting or in the
event that the date of the applicable annual meeting is changed by more than 30
days from the date of our last annual meeting, a shareholder's notice must be
received at our principal executive offices no later than the close of business
on the tenth day following the earlier of the day on which notice of the meeting
date was mailed or public disclosure of the meeting date was made. In order to
be valid, a shareholder's notice to our corporate secretary must set forth:

                *          the name and address, as they appear on our records,
                           of the shareholder nominating the persons, and the
                           name and address of the beneficial owner, if any, on
                           whose behalf the nomination is made;

                *          the class and number of shares of our capital stock
                           that are owned beneficially and of record by the
                           shareholder of record and by the beneficial owner, if
                           any, on whose behalf the nomination is made;

                *          any material interest or relationship that the
                           shareholder of record and/or the beneficial owner, if
                           any, on whose behalf the nomination is made may
                           respectively have with the nominee; and

any other information required to be disclosed in solicitations of proxies for
election of directors, or information otherwise required pursuant to Regulation
14A under the Securities Exchange Act of 1934 relating to any person that the
shareholder proposes to nominate for election or re-election as a director,
including the nominee's written consent to being named in the proxy statement as
a nominee and to serving as a director if elected.

                             AUDIT COMMITTEE REPORT

         Management is responsible for our internal controls and financial
reporting process. Our independent accountants for fiscal 2005, Stonefield
Josephson, Inc. are responsible for performing an independent audit of our
financial statements in accordance with auditing standards generally accepted in
the United States of America and issuing their report. The audit committee's
responsibility is to monitor and oversee these processes.

         In connection with these responsibilities, the audit committee met with
management and the independent accountants to review and discuss the financial
statements for the fiscal year ended September 30, 2005. The audit committee
also discussed with the independent accountants the matters required by
Statement on Auditing Standards No. 61 (communication with audit committees).
The audit committee also received written disclosures from the independent
accountants required by Independence Standards Board Standard No. 1
(Independence discussions with audit committees), and the audit committee
discussed with the independent accountants that firm's independence.

         Based upon the audit committee's discussions with management and the
independent accountants, and the audit committee's review of the representations
of management and the independent accountants, the audit committee recommended
that the board of directors include the audited financial statements in
Hennessy's annual report on Form 10-KSB for the fiscal year ended September 30,
2005 filed with the Securities and Exchange Commission.

                                        Daniel G. Libarle, Chairman
                                        Henry Hansel
                                        Thomas L. Seavey


         The preceding report shall not be deemed incorporated by reference by
any general statement incorporating by reference this proxy statement into any
filing under the Securities Act of 1933 (the "1933 Act") or the Securities
Exchange Act of 1934 (the "1934 Act"), except to the extent the Company
specifically incorporates this information by reference, and shall not otherwise
be deemed filed under the 1933 Act or the 1934 Act.

                    INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

         On December 30, 2004, we dismissed our auditors, Pisenti & Brinker,
LLP, and appointed Stonefield Josephson, Inc. as our new independent auditors,
effective December 30, 2004. This change was approved by the audit committee.

         During the two most recent fiscal years ended September 30, 2004, and
the subsequent interim period through December 30, 2004, there were no
disagreements between us and Pisenti & Brinker on any matter of accounting
principles or practices, financial statement disclosure, or auditing scope or
procedure, which disagreements, if not resolved to Pisenti & Brinker's
satisfaction, would have caused Pisenti & Brinker to make reference to the
subject matter of the disagreement in connection with its reports.

         The audit reports of Pisenti & Brinker on our financial statements as
of and for the fiscal years ended September 30, 2004 and September 30, 2003 did
not contain any adverse opinion or disclaimer of opinion, nor were they
qualified or modified as to uncertainty, audit scope or accounting principles.

         The board of directors has selected Stonefield Josephson, Inc. to serve
as our independent certified public accountants for the current fiscal year
ending September 30, 2006. That firm has served as our auditors beginning on
December 30, 2004 and for the fiscal year ended September 30, 2005.
Representatives of Stonefield Josephson are expected to be present at the annual
meeting of shareholders and will be accorded the opportunity to make a
statement, if they so desire, and to respond to appropriate questions.

         The following table provides information relating to the fees KPMG LLP
(our auditors until June 3, 2003), Pisenti & Brinker and Stonefield Josephson
billed to Hennessy Advisors, Inc., for the fiscal years ended September 30, 2005
and 2004.

((1)) Tax fees are for preparation of federal and state income tax returns.

((2)) Other fees include attendance at Audit Committee and Shareholder Meetings.

         All decisions regarding selection of independent accounting firms and
approval of accounting services and fees are made by our audit committee in
accordance with the provisions of the Sarbanes-Oxley Act of 2002. There are no
exceptions to the policy of securing pre-approval of our audit committee for any
service provided by our independent accounting firm.

                                  OTHER MATTERS

         The board of directors does not know of any other matters to come
before the meeting. However, if any other matters properly come before the
meeting, the persons designated as proxies intend to vote in accordance with
their best judgment on such matters. If any other matter should come before the
meeting, action on the matter will be approved if the number of votes cast in
favor of the matter exceeds the number opposed.

                  SHAREHOLDER PROPOSALS AND COMMUNICATIONS WITH
                             THE BOARD OF DIRECTORS

         Regulations of the Securities and Exchange Commission require proxy
statements to disclose the date by which shareholder proposals must be received
by us in order to be included in our proxy materials for the next annual
meeting. In accordance with these regulations, shareholders are hereby notified
that if, pursuant to Rule 14a-8, they wish a proposal to be included in our
proxy statement and form of proxy relating to the 2007 annual meeting, a written
copy of their proposal must be received at our principal executive offices no
later than September 29, 2006. Proposals must comply with the proxy rules
relating to shareholder proposals in order to be included in our proxy
materials.


                                      -12-


         Notice to us of a shareholder proposal submitted otherwise than
pursuant to Rule 14a-8 will be considered untimely under our bylaws if we
receive it after September 29, 2006, and will not be placed on the agenda for
the 2007 annual meeting.

         To ensure prompt receipt by Hennessy, proposals should be sent
certified mail, return receipt requested.

         Shareholders who wish to communicate with the board of directors or
with a particular director may send a letter to our corporate secretary at our
principal executive offices, at 7250 Redwood Boulevard, Suite 200, Novato,
California 94945. The mailing envelope should contain a clear notation
indicating that the enclosed letter is a "Shareholder-Board Communication" or
"Shareholder-Director Communication." All such letters should identify the
author as a shareholder and clearly state whether the intended recipients are
all members of the board or just certain specified individual directors. Our
corporate secretary will make copies of all such letters and circulate them to
the appropriate director or directors.

         Hennessy does not have a formal policy requiring directors to attend
annual meetings. However, because the annual meeting generally is held on the
same day as a regular board meeting, we anticipate that directors would attend
the annual meeting unless, for some reason, they are unable to attend the board
meeting on the same date. All directors (other than Charles W. Bennett, who
joined the board in August 2005) attended the 2005 annual meeting.

                                  ANNUAL REPORT

         A copy of our annual report on Form 10-KSB for the fiscal year ended
September 30, 2005 accompanies this proxy statement. Additional copies may be
obtained by writing to Teresa M. Nilsen, at our principal executive offices, at
7250 Redwood Boulevard, Suite 200, Novato, California 94945.

                            EXPENSES OF SOLICITATION

         The cost of soliciting proxies will be borne by Hennessy. We may
reimburse brokers and other persons holding stock in their names, or in the
names of nominees, for their expenses for sending proxy material to principals
and obtaining their proxies.

         PLEASE SPECIFY YOUR CHOICES, DATE, SIGN AND RETURN THE ENCLOSED PROXY 
IN THE ENCLOSED ENVELOPE, POSTAGE FOR WHICH HAS BEEN PROVIDED.  YOUR PROMPT 
RESPONSE WILL BE APPRECIATED.
