NUVEEN SENIOR INCOME FUND - NSL

GENERAL INFORMATION

This Proxy Statement is furnished in connection with the solicitation by the
Board of Trustees of Nuveen Senior Income Fund (the "Fund"), of proxies to be
voted at the Annual Meeting of Shareholders of the Fund to be held on December
19, 2001 (the "Annual Meeting"), and at any and all adjournments thereof.

On the matter coming before the Fund's Annual Meeting as to which a choice has
been specified by the shareholders of the Fund on the proxy, the shares will be
voted accordingly. If no choice is so specified, the shares of the Fund will be
voted FOR the election of the nominees for trustee, as listed in this Proxy
Statement. Shareholders of the Fund who execute proxies may revoke them at any
time before they are voted by filing with the Fund a written notice of
revocation, by delivering a duly executed proxy bearing a later date, or by
attending the Annual Meeting and voting in person.

A quorum of shareholders is required to take action at the Fund's Annual
Meeting. A majority of the shares entitled to vote at the Annual Meeting,
represented in person or by proxy, will constitute a quorum of shareholders at
the Annual Meeting. However, for the purpose of electing two trustees by the
holders of TAPS only, the holders of 33 1/3% of the TAPS entitled to vote will
constitute a quorum. Votes cast by proxy or in person at the Annual Meeting will
be tabulated by the inspectors of election appointed for the Annual Meeting. The
inspectors of election will determine whether or not a quorum is present at the
Annual Meeting. The inspectors of election will treat abstentions and "broker
non-votes" (i.e., shares held by brokers or nominees, typically in "street
name," as to which (i) instructions have not been received from the beneficial
owners or persons entitled to vote and (ii) the broker or nominee does not have
discretionary voting powers on a particular matter) as present for purposes of
determining a quorum.

Those persons who were shareholders of record at the close of business on
October 22, 2001 will be entitled to one vote for each share held. As of October
22, 2001, 29,722,636 common shares and 1,840 TAPS of the Fund were issued and
outstanding.

This Proxy Statement is first being mailed to shareholders of the Fund on or
about November 20, 2001.

                           1


1. ELECTION OF TRUSTEES

At the Fund's Annual Meeting, seven (7) trustees are to be elected to serve
until the next Annual Meeting and until their successors shall have been duly
elected and qualified. Under the terms of the Fund's organizational documents,
holders of TAPS are entitled to elect two (2) trustees, and the remaining
trustees are to be elected by holders of Common Shares and TAPS, voting together
as a single class.

          (a) Five trustees are to be elected by holders of Common Shares and
     the TAPS voting together as a single class. Trustees Bacon, Bennett, Evans,
     Leafstrand and Wellington are nominees for election by all shareholders.

          (b) Holders of TAPS are entitled to elect two of the trustees.
     Trustees Kissick and Schwertfeger are nominees for election by holders of
     TAPS.

The affirmative vote of a plurality of the shares present and entitled to vote
will be required to elect the trustees of the Fund.

It is the intention of the persons named in the enclosed proxy to vote the
shares represented thereby for the election of the nominees listed below unless
the proxy is marked otherwise. Each of the nominees has agreed to serve as a
trustee of the Fund if elected. However, should any nominee become unable or
unwilling to accept nomination or election, the proxies for the Fund will be
voted for one or more substitute nominees designated by the Fund's present Board
of Trustees.

Other than Timothy R. Schwertfeger, none of the trustees have ever been a
director or an employee of Nuveen Investments or any affiliate of Nuveen
Investments.

The following table shows each nominee's date of birth, principal occupation and
other business affiliations and the number of shares of the Fund which each
nominee beneficially owned as of September 30, 2001. None of the nominees
beneficially owned any TAPS as of September 30, 2001. All of the trustees,
except William E. Bennett, have been trustees of the Fund since its organization
in 1999. Mr. Bennett has been a trustee of the Fund since January 31, 2001.

                           2


THE BOARD OF TRUSTEES OF THE FUND UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS GIVE
VOTING INSTRUCTIONS FOR THE ELECTION OF THE NOMINEES NAMED BELOW.

(1) In addition to the Fund, the trustees are also trustees of one fund managed

funds advised by Nuveen Institutional Advisory Corp. ("NIAC"). In addition, Mr.
Schwertfeger is a director of 74 closed-end funds and 30 open-end funds advised
by Nuveen Advisory Corp. ("NAC").

(2) The number shown reflects the aggregate number of common shares beneficially
owned by the nominee in the Fund, the other fund advised by NSLAM, the funds
advised by NAC and the funds advised by NIAC. For each trustee, the number shown
includes share equivalents of certain Nuveen funds in which the trustee is
deemed to be invested pursuant to the Deferred Compensation Plan for Independent
Trustees, as more fully described under "Compensation." For Mr. Schwertfeger,
the number also includes shares held in Nuveen's 401(k)/Profit Sharing Plan.

The above persons have sole voting power and sole investment power as to the

COMPENSATION

The trustees affiliated with Nuveen or Nuveen Senior Loan Asset Management Inc.
("NSLAM") serve without any compensation from the Fund. Trustees who are not
affiliated with Nuveen or NSLAM ("Independent Trustees") receive a $35,000
annual retainer for serving as a trustee for all funds managed by NSLAM and
Nuveen Institutional Advisory Corp. ("NIAC"), $1,000 fee per day plus expenses
for attendance in person at all meetings (other than a meeting of the dividend
and valuation committee held solely to declare a dividend) held on a day on
which no regular Board meeting is held, $500 for attendance by telephone of such
meetings and $200 for attendance in person or by telephone at a meeting of the
dividend and valuation committee. The annual retainer, fees and expenses are
allocated among the funds on the basis of relative net asset sizes.

The Board of Trustees of certain Nuveen funds (the "Participating Funds") have
adopted a Deferred Compensation Plan for Independent Trustees (the "Plan").
Under the Plan, the Independent Trustees of the Participating Funds may defer
receipt of all, or a portion of, their compensation for services to the
Participating Funds. Any deferred amount is treated as though an equivalent
dollar amount had been invested in shares of one or more eligible Nuveen Funds
selected by the participant trustee.

The Fund is a Participating Fund and each Independent Trustee has elected to
defer all or a portion of their compensation. Total deferred fees for the Fund
for fiscal year 2001 (including the return from the assumed investment in the
eligible Nuveen funds) payable are shown in the Deferred Fees column below.

The following table shows, for each trustee who is not affiliated with Nuveen or
NSLAM, (1) the aggregate compensation paid by the Fund for its fiscal year ended
July 31, 2001, (2) the total deferred fees and (3) the total compensation paid
by the funds advised by NSLAM and the funds advised by NIAC during the calendar
year 2000.

The John Nuveen Company ("JNC"), parent company of NSLAM, maintains its
charitable contributions programs to encourage the active support and
involvement of individuals in the civic activities of their community. These
programs include a matching contributions program and a direct contributions
program.

The Independent Trustees of the Fund are eligible to participate in the
charitable contributions program of JNC. Under the matching program, JNC will
match the personal contributions of an Independent Trustee to Section 501(c)(3)
organizations up to an aggregate maximum amount of $10,000 during any calendar
year. Under its direct (non-matching) program, JNC makes contributions to
qualifying Section 501(c)(3) organizations, as approved by the corporate
contributions committee of JNC. The Independent Trustees are also eligible to
submit proposals to the committee requesting that contributions be made under
this program to Section 501(c)(3) organizations identified by the Independent
Trustees, in an aggregate amount not to exceed $5,000 during any calendar year.
Any contribution made by JNC under the direct program is made solely at the
discretion of the corporate contributions committee.

William L. Kissick and Timothy R. Schwertfeger serve as the current members of
the executive committee of the Fund's Board of Trustees. The Fund's executive
committee, which meets between regular meetings of the Board of Trustees, is
authorized to exercise all of the powers of the Board of Trustees. The executive
committee of the Fund did not hold any meetings during the fiscal year ended
July 31, 2001.

Thomas E. Leafstrand, William E. Bennett and Timothy R. Schwertfeger are the
current members of the dividend and valuation committee of the Fund. The
dividend and valuation

                           5


committee is authorized to declare distributions on the Fund's shares including,
but not limited to, regular and special dividends, capital gains and ordinary
income distributions. The dividend and valuation committee of the Fund held
twelve meetings during the fiscal year ended July 31, 2001.

The Fund's Board of Trustees has an audit committee currently composed of James
E. Bacon, William E. Bennett, Jack B. Evans, William L. Kissick and Thomas E.
Leafstrand, trustees of the Fund who are not "interested persons" and who are
"independent" as that term is defined in Section 303.01(B)(2)(a) and (3) of the
New York Stock Exchange's listing standards. The Fund's audit committee reviews
the work and any recommendations of the Fund's independent auditors. Based on
such review, it is authorized to make recommendations to the Board of Trustees.
The audit committee of the Fund held two meetings during the fiscal year ended
July 31, 2001. The audit committee has adopted a written charter. A copy of the
written charter is attached as Appendix A to this proxy statement.

Nomination of those trustees who are not "interested persons" of the Fund is
committed to a nominating and governance committee composed of the trustees who
are not "interested persons" of the Fund. Members of each Fund's nominating and
governance committee are James E. Bacon, William E. Bennett, Jack B. Evans,
William L. Kissick, Thomas E. Leafstrand and Sheila W. Wellington. The Fund's
nominating and governance committee identifies and recommends individuals to be
nominated for election as non-interested trustees. The committee also reviews
matters relating to (1) the composition, duties, recruitment, independence and
tenure of trustees, (2) the selection of various committee assignments, and (3)
trustee education, board meetings and board performance. The nominating and
governance committee of the Fund held four meetings during the fiscal year ended
July 31, 2001. No policy or procedure has been established as to the
recommendation of trustee nominees by shareholders.

The Board of Trustees of the Fund held four regular board meetings and two
special board meetings during the fiscal year ended July 31, 2001. During the
last fiscal year, each Trustee attended 75% or more of the Fund's Board meetings
and committee meetings (if a member thereof).

The following table sets forth information with respect to each executive
officer of the Fund, other than Mr. Schwertfeger who is a trustee and included
in the table relating to the nominees for the Board. Officers of the Fund
receive no compensation from the Fund. The term of office of all officers will
expire in July 2002.

On September 30, 2001, trustees and executive officers of the Fund as a group
beneficially owned 441,450 common shares of all of the Nuveen Funds managed by
NIAC, NSLAM and Nuveen Advisory Corp. ("NAC") (including share equivalents of
certain Nuveen funds in which the trustee is deemed to be invested in connection
with the deferral of compensation by trustees pursuant to the Plan and shares
held by the executive officers in Nuveen's 401(k)/Profit Sharing Plan). As of
September 30, 2001, the trustees and executive officers of the Fund as a group
owned less than 1% of the outstanding shares of the Fund. As of October 22,
2001, no shareholder owned more than 5% of any class of shares of the Fund.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 30(f) of the Investment Company Act of 1940 and Section 16(a) of the
Securities Act of 1934 require each of the Fund's officers and trustees,
investment adviser, affiliated persons of the investment adviser and persons who
own more than ten percent of a registered class of the Fund's equity securities
to file forms with the Securities and Exchange Commission ("SEC") and the New
York Stock Exchange reporting their affiliation with the Fund and reports of
ownership and changes in ownership of Fund shares. These persons and entities
are required by SEC regulation to furnish the Fund with copies of all such forms
they file. Based on a review of these forms furnished to the Fund, the Fund
believes that during the fiscal year ended September 30, 2001, the Fund's
officers and trustees, investment adviser and affiliated persons of the
investment adviser complied with all such applicable filing requirements. To the
knowledge of management of the Fund, no shareholder of the Fund owns more than
10% of a registered class of any Fund's equity securities.

AUDIT COMMITTEE REPORT

The audit committee of the Board of Trustees of the Fund is responsible for
assisting the Board in monitoring (1) the quality and integrity of the Fund's
financial statements, (2) the Fund's compliance with regulatory requirements,
and (3) the independence and performance of the Fund's independent and internal
auditors. Among other responsibilities, the committee reviews, in its oversight
capacity, the Fund's annual financial statements with both management and the
independent auditors and the committee meets periodically with the independent
and internal auditors to consider their evaluation of the Fund's financial and
internal controls. The committee also recommends to the Board of Trustees the
selection of the Fund's independent auditors. The committee is currently
composed of five non-employee trustees and operates under a written charter
adopted and approved by the Board of Trustees. Each committee member is
independent as defined by New York Stock Exchange listing standards. A copy of
the Audit Committee Charter is attached to the proxy statement as Appendix A.

The committee, in discharging its duties, has met with and held discussions with
management and the Fund's independent and internal auditors. Management has
represented to the independent auditors that the Fund's financial statements
were prepared in accordance with generally accepted accounting principles. The
committee has also discussed with the independent auditors the matters required
to be discussed by Statement on Auditing Standards No. 61 (Communications with
Audit Committees). The Fund's independent auditors provided to the committee the
written disclosure required by Independent Standards Board Standard No. 1
(Independent Discussions with Audit Committees), and the committee discussed
with representatives of the independent auditor their firm's independence. As
provided in the Audit Committee Charter, it is not the committee's
responsibility to

                           8


determine, and the considerations and discussions referenced above do not
ensure, that the Fund's financial statements are complete and accurate and
presented in accordance with generally accepted accounting principles.

Based on the committee's review and discussions with management and the
independent auditors, the representations of management and the report of the
independent auditors to the committee, the committee has recommended that the
Board of Trustees include the audited financial statements in the Fund's Annual
Report.

The members of the audit committee are:

James E. Bacon
William E. Bennett
Jack B. Evans
William L. Kissick
Thomas E. Leafstrand

APPOINTMENT OF INDEPENDENT AUDITORS

The Board of Trustees has appointed KPMG LLP, certified public accountants, as
independent auditors to examine the annual consolidated statements for fiscal
2002. A representative of KPMG LLP will be present at the meeting to make a
statement, if such representative so desires, and to respond to shareholders'
questions.

AUDIT AND RELATED FEES

AUDIT FEES. The aggregate fees billed by KPMG LLP for professional services for
the audit of the Fund's financial statements for fiscal 2001 were as follows:

their capacity as independent auditor for the Fund.

The audit committee has considered whether the non-audit services provided by
KPMG LLP are compatible with maintaining the independence of KPMG LLP.

                     NUVEEN MANAGEMENT INVESTMENT COMPANIES

                            AUDIT COMMITTEE CHARTER

                                   July, 2000

ORGANIZATION

There shall be a committee of each Board of Directors/Trustees of the Nuveen
Management Investment Companies to be known as the Audit Committee. The Audit
Committee shall be composed of at least three Directors/Trustees. Audit
Committee members shall be independent of the Management Investment Companies
and free of any relationship that, in the opinion of the Directors/Trustees,
would interfere with their exercise of independent judgment as a committee
member. Each such member of the Audit Committee shall have a basic understanding
of finance and accounting and be able to read and understand fundamental
financial statements, and at least one such member shall have accounting or
related financial management expertise, in each case as determined by the
Directors/ Trustees, exercising their business judgment.

STATEMENT OF POLICY

The Audit Committee shall assist the Board in monitoring (1) the accounting and
reporting policies and practices of the Management Investment Companies
(hereafter referred to as "Funds" or individually "Fund"), (2) the quality and
integrity of the financial statements of the Funds, (3) the compliance by the
Funds with legal and regulatory requirements and (4) the independence and
performance of the external and internal auditors. In doing so, the Audit
Committee shall seek to maintain free and open means of communication among the
Directors, the independent auditors, the internal auditors and the management of
Nuveen.

The Audit Committee shall have the authority in its discretion to retain special
legal, accounting or other consultants to advise the Committee. The Audit
Committee may request any officer or employee of the John Nuveen Company or the
Funds' independent auditors or outside counsel to attend a meeting of the
Committee or to meet with any members of, or consultants to, the Committee. The
Funds' independent auditors and internal auditors shall have unrestricted
accessibility at any time to committee members.

RESPONSIBILITIES

Fund management has the primary responsibility to establish and maintain systems
for accounting, reporting and internal control.

The independent auditors have the primary responsibility to plan and implement
an audit, with proper consideration given to the accounting, reporting and
internal controls. The independent auditors are ultimately accountable to the
Board and Audit Committee. It is the ultimate responsibility of the Board and
the Audit Committee for selection, evaluation and replacement of the independent
auditors.

                           11


In carrying out its responsibilities the Audit Committee believes its policies
and procedures should remain flexible, in order to react to changing conditions
and requirements applicable to the Funds.

The Audit Committee is responsible for the following:

     Fund Financial Statements:

       1. Reviewing the annual audited financial statements with Fund management
          including major issues regarding accounting and auditing principles
          and practices.

       2. Requiring the independent auditors to deliver to the Chairman of the
          Committee a timely report on any issues relating to the significant
          accounting policies, management judgments and accounting estimates or
          other matters that would need to be communicated under SAS 61, that
          arise during the auditor's review of the Fund's financial statements,
          which information shall be further communicated by the Chairman to the
          other members of the Committee, as deemed necessary or appropriate in
          the judgment of the Chairman.

     With respect to the independent auditors:

       3. Receiving periodic reports (including a formal written statement
          delineating all relationships between the auditors and the Funds) from
          the firms of independent auditors regarding their independence, their
          membership in the SEC practice section of the AICPA and their
          compliance with all applicable requirements for independence and peer
          review, and discussing such reports with the auditors.

       4. Reviewing and recommending to the Directors/Trustees the independent
          auditors to be selected to audit the annual financial statements of
          the Funds.

       5. Meeting with the independent auditors and Fund management to review
          the scope and fees of the proposed audits for the current year and the
          audit procedures to be utilized. At the conclusion of the audit,
          reviewing such audit results, including any comments or
          recommendations of the independent auditors, any significant changes
          required from the originally planned audit programs and any
          adjustments to such statements recommended by the auditors.

       6. Providing sufficient opportunity at all meetings of the Audit
          Committee for the independent auditors to meet with the members of the
          Audit Committee without members of Fund management being present.

     With respect to any internal auditor:

       7. Reviewing the internal audit function as it relates to the Funds
          including the proposed programs for the coming year. It is not the
          obligation or responsibility of the Audit Committee to confirm the
          independence of any Nuveen internal auditors performing services
          relating to the Funds or to approve any termination or replacement of
          the Nuveen Manager of Internal Audit.

                           12


       8. Receiving a summary of findings from any completed internal audits
          pertaining to the Funds and a progress report on the proposed internal
          audit plan for the Funds, with explanations for significant deviations
          from the original plan.

     Other responsibilities:

       9. Receiving and reviewing periodic or special reports issued on
          exposure/controls, irregularities and control failures related to the
          Funds.

      10. Reviewing with the independent auditors, with any internal auditor and
          with Fund management, the adequacy and effectiveness of the accounting
          and financial controls of the Funds, and elicit any recommendations
          for the improvement of internal control procedures or particular areas
          where new or more detailed controls or procedures or particular areas
          where new or more detailed controls or procedures are desirable.
          Particular emphasis should be given to the adequacy of such internal
          controls to expose payments, transactions or procedures which might be
          deemed illegal or otherwise improper.

      11. Reviewing the reports of examinations by regulatory authorities.

      12. Reporting to the Directors/Trustees on the results of the activities
          of the Committee.

      13. Performing any special reviews, investigations or oversight
          responsibilities requested by the Directors/Trustees.

      14. With respect to the Exchange-Traded Funds, preparing any report
          required by the rules of the SEC to be included in a proxy statement
          for a fund.

      15. Reviewing and reassessing annually the adequacy of this charter and
          providing a recommendation to the Board of Directors/Trustees for
          approval of any proposed changes deemed necessary or advisable by the
          Committee.

Although the Audit Committee shall have the authority and responsibilities set
forth in this Charter, it is not the responsibility of the Audit Committee to
plan or conduct audits or to determine that the Funds' financial statements are
complete and accurate and are in accordance with generally accepted accounting
principles. That is the responsibility of management and the independent
auditors. Nor is it the duty of the Audit Committee to conduct investigations,
to resolve disagreements, if any, between management and the independent
auditors or to ensure compliance with laws and regulations.
