                    Met Investors Series Trust (the "Trust")
                   Preliminary-Proxy Statement on Schedule 14A
                                 CIK 0001126087
                               File No. 811-10183


Ladies and Gentlemen:

     This letter is in response to certain comments from Ms. Alison White of the
Staff with respect to the Trust's  Preliminary  Proxy  Statement  filed with the
Commission on December 28, 2007. Where noted, changes, as applicable,  have been
made to the Proxy  Statement.  All page  references  refer to the pages of these
documents  which have been marked to show  changes  from the  previous  versions
included in the Preliminary Proxy Statement.

1.   Comment:  The number of  portfolios  of the Trust  listed in the section on
     "Information  about the Board Nominees" is 44. The footnote to this section
     lists 36 portfolios of the Trust. Please reconcile.

     Response: The footnote on page 12 has been corrected.


2.   Comment:  Pursuant to Section  407(b)(1) of Reg. S-K,  include in the proxy
     the name of each  incumbent  director  who during the last full fiscal year
     attended fewer than 75% of the total number of board and committee meetings
     in which he or she served.

     Response:  Section  407(b)(1) of Reg.  S-K only  requires  disclosure  if a
     trustee  did not attend at least 75% of the board and  committee  meetings.
     Since all of the Trust's  trustees  attended at least 75% of such meetings,
     no additional disclosure is required.


3.   Comment:  Pursuant to Section  407(c)(2)(vii)  of Reg. S-K, with respect to
     new nominees to the Board, state what category of persons (security holder,
     director,  chief executive officer,  other executive officer or employee of
     the investment adviser, principal underwriter or any affiliate) recommended
     each nominee.

     Response: Additional disclosure has been added to page 14.

     Comment: Include Tandy language in your response letter.

4.   Response: The reported language is included in this letter.


     In connection with this filing,  the Trust acknowledges that: (1) the Trust
is  responsible  for the adequacy and accuracy of the disclosure in the filings;
(2) staff comments or changes to disclosure in response to staff comments in the
filings  reviewed by the staff do not foreclose the  Commission  from taking any
action with respect to filing;  (3) the Trust may not assert staff comments as a
defense in any  proceeding  initiated by the  Commission or any person under the
federal securities laws of the United States.

     The Trust will file its definitive  Proxy  Statement on or about January 7,
2008.

     If you have any questions, please feel free to call me at (202) 775-1205.

                                                   Very truly yours,


                                                   /s/ Robert N. Hickey

Board Committees

The Board of Trustees has three standing  committees:  the Audit Committee,  the
Nominating, Governance and Compensation Committee, and the Valuation Committee.

Audit Committee. The Audit Committee consists of all of the Independent
Trustees. The Audit Committee's function is to recommend to the Board
independent accountants to conduct the annual audit of the Trust's financial
statements; review with the independent accountants the outline, scope and
results of the annual audit; and review the performance and fees charged by the
independent accountants for professional services. In addition, the Audit
Committee meets with the independent accountants and representatives of
management to review accounting activities and areas of financial reporting and
control. The Audit Committee held four meetings during the fiscal year ended
December 31, 2007.

Nominating, Governance and Compensation Committee. The Nominating, Governance
and Compensation Committee consists of all of the Independent Trustees. The
Nominating, Governance and Compensation Committee has a charter and the
Committee's function is to nominate and evaluate Independent Trustee candidates
and review the compensation arrangement for each of the Trustees. Given the
nature of the Trust, in that its assets are used to fund the benefits under
variable annuity and life insurance plans, the Nominating, Governance and
Compensation Committee will not consider nominees recommended by shareholders.
The Nominating, Governance and Compensation Committee held six meetings during
the fiscal year ended December 31, 2007. A copy of the Nominating, Governance
and Compensation Committee's charter is attached as Appendix A.

When evaluating a person as a potential nominee to serve as an Independent
Trustee, the Nominating, Governance and Compensation Committee will generally
consider, among other factors: (i) whether the person is "independent" and
otherwise qualified under applicable laws and regulations to serve as a Trustee;
(ii) whether the person is willing to serve, and willing and able to commit the
time necessary for attendance at meetings and the performance of the duties of
an Independent Trustee; (iii) the contribution that the person can make to the
Board and the Portfolios, with consideration being given to the person's
business, academic or other experience and education and to such other factors
as the Committee may consider relevant; (iv) the character and integrity of the
person; and (v) desirable personality traits, including independence, leadership
and ability to work with others. It is the intent of the Nominating, Governance
and Compensation Committee that at least one Independent Trustee be an "audit
committee financial expert" as such term is defined by the SEC. The process of
identifying nominees involves the consideration of candidates recommended by one
or more of the following sources: current Trustees, officers, and any other
source the Nominating, Governance and Compensation Committee deems appropriate.
In addition, the Nominating, Governance and Compensation Committee may use the
services of a professional search firm to identify or evaluate or assist in
identifying or evaluating potential candidates or nominees.


Susan C. Gause was recommended to the Nominating, Governance and Compensation
Committee by an Independent Trustee and Robert Boulware was recommended to the
Committee by the chief executive officer of the Trust's investment manager.


Valuation Committee. The Valuation Committee currently consists of Elizabeth M.
Forget, Richard C. Pearson, Jeffrey Tupper, Thomas McDevitt, Bryan Andersen and
such other officers of the Trust and the Manager, as well as such officers of
any adviser to any Portfolio as are deemed necessary by Ms. Forget, Mr. Pearson,
Mr. Tupper, Mr. McDevitt or Mr. Andersen from time to time, each of whom shall
serve at the pleasure of the Board of Trustees as members of the Valuation
Committee. The Valuation Committee determines the value of any of the Trust's
securities and assets for which market quotations are not readily available or
for which valuations cannot otherwise be provided. The Valuation Committee held
21 meetings during the fiscal year ended December 31, 2007.
