     RE:  MFS Variable  Insurance Trust II
          Registration  Statements on Form N-14
          -File Nos. 333-161866; 333-161867

Ladies and Gentlemen:

         On behalf of MFS Variable Insurance Trust II (File Nos. 2-83616;
811-3732) (the "Registrant"), this letter sets forth our responses to your
comments on the above-referenced registration statements on Form N-14 filed on
September 11, 2009 (the "Registration Statements") in connection with the
following proposed reorganizations: MFS Capital Appreciation Portfolio into MFS
Massachusetts Investors Growth Stock Portfolio and MFS Mid Cap Value Portfolio
into MFS Value Portfolio, each a series of the Trust. The series of the Trust
are hereinafter collectively referred to as the "Funds."

General Comments

1.   Comment:  Please file a "Tandy" representation letter in connection with
               the comment process for the above-referenced Registration
               Statements.

     Response: A "Tandy" representation letter will be filed on or before the
               date hereof.

Comments Applicable to Both Registration Statements

2.   Comment:  In each Prospectus/Proxy Statement, the estimated costs
               associated with the reorganization are currently disclosed in the
               sub-section entitled "Reorganization Fees and Expenses" under the
               caption  "Information  About  the  Reorganization."  Please  also
               disclose the  estimated  reorganization  costs in the  "Synopsis"
               section of the Prospectus/Proxy Statement.

     Response: The requested change will be made.

3.   Comment:  In Question 5 under the caption "Synopsis", each Prospectus/Proxy
               Statement  currently states that the pro forma combined fund will
               pay management fees pursuant to the respective  acquiring  fund's
               lower  management fee schedule.  Please clarify this statement by
               noting that

               the effective  management fee rate of the pro forma combined fund
               upon  consummation  of the  reorganization  is expected to be the
               same as the  effective  management  fee  incurred  by each of the
               acquired  fund and the  acquiring  fund  during  each fund's most
               recent fiscal year ended December 31, 2008.

     Response: The requested change will be made.

4.   Comment:  In the sub-section "Capitalization" under the caption
               "Information   About   the   Reorganization,"   the  "Pro   Forma
               Adjustments"   column  in  the  capitalization   table  currently
               discloses the total number of shares to be issued to the acquired
               fund  assuming  that  the  reorganization  occurred  on the  date
               specified in the table. Please revise the "Pro Forma Adjustments"
               column  so  that  the  share  amount   adjustments   reflect  the
               difference between (i) the sum of the acquired fund and acquiring
               fund shares  outstanding prior to the reorganization and (ii) the
               "Pro  Forma  Combined  Portfolio"  shares  outstanding   assuming
               completion  of the  reorganization.  This comment also applies to
               the Pro Forma Statement of Assets and Liabilities included in the
               registration statement for the proposed reorganization of the MFS
               Capital   Appreciation   Portfolio  into  the  MFS  Massachusetts
               Investors Growth Stock Portfolio.

     Response: The capitalization tables and the Pro Forma Statement of
               Assets and Liabilities will be updated accordingly.

Registration Statement relating to the proposed reorganization of the MFS
Capital Appreciation Portfolio (the "Capital Appreciation Portfolio") into the
MFS Massachusetts Investors Growth Stock Portfolio (the "Massachusetts Investors
Growth Stock Portfolio").

5.   Comment:  In the sub-section "Reorganization Fees and Expenses" under the
               caption  "Information About the  Reorganization",  please include
               disclosure  stating that minimal,  if any, costs  associated with
               portfolio  repositioning  are  anticipated in connection with the
               reorganization,  consistent with the disclosure  included earlier
               in the Prospectus/Proxy Statement.

     Response: The requested change will be made.

6.   Comment:  In light of the fact that the Capital Appreciation Portfolio has
               a larger asset base than the Massachusetts Investors Growth Stock
               Portfolio,  please  support the position  that the  Massachusetts
               Investors   Growth  Stock  Portfolio  should  be  the  accounting
               survivor in the reorganization.

     Response: We believe that the Massachusetts Investors Growth Stock
               Portfolio should be the accounting survivor in the
               reorganization. Based on the factors outlined in the North
               American Securities Trust No-Action Letter (August 5, 1994)
               (the "NAST Letter"), we believe that the post-merger combined
               fund will most closely resemble the Massachusetts Investors
               Growth Stock Portfolio, and that therefore, the Massachusetts
               Investors

Securities and Exchange Commission

               Growth Stock Portfolio  should be the accounting  survivor in the
               reorganization.(1)  As noted in the  Prospectus/Proxy  Statement,
               the investment adviser, portfolio manager,  investment objective,
               and  investment  restrictions  of the Funds are the same, and the
               portfolio  composition  of the  Funds is  substantially  similar.
               However,  the  management  fee schedule and net expense ratios of
               the post-reorganization  combined fund will more closely resemble
               those of the Massachusetts  Investors Growth Stock Portfolio.  In
               addition,  the investment policies of the combined fund will more
               closely  resemble  the   Massachusetts   Investors  Growth  Stock
               Portfolio,  as the combined  fund will  continue to be subject to
               Rule 35d-1 under the Investment  Company Act of 1940, as amended,
               and as a result will  continue to have a policy of  investing  at
               least  80%  of its  assets  in  equity  securities.  The  Capital
               Appreciation Portfolio is not subject to Rule 35d-1 and therefore
               does not have such an investment policy.

               While the Capital Appreciation Portfolio has a larger asset base,
               we note that each Fund has substantial  assets and that the sizes
               of the Funds are  somewhat  similar.  For  example,  assuming the
               reorganization  occurred  on June 30,  2009,  the  assets  of the
               Massachusetts  Investors  Growth Stock  Portfolio would represent
               approximately 45% of the approximate  $462.5 million in assets of
               the surviving fund.

               We have discussed our position with the Funds' auditor,  Deloitte
               & Touche LLP ("D&T"), and D&T did not object to our position that
               Massachusetts  Investors  Growth  Stock  Portfolio  should be the
               accounting  survivor  in the  transaction.  The  outcome  of that
               conclusion,   consistent  with  the  NAST  Letter,  is  that  the
               historical  performance record of Massachusetts  Investors Growth
               Stock  Portfolio  would be used for the surviving  fund following
               the reorganization.
__________________
(1) In North American Security Trust, the SEC staff stated:

         "In determining whether a surviving fund, or a new fund resulting from
         a reorganization, may use the historical performance of one of several
         predecessor funds, funds should compare the attributes of the surviving
         or new fund and the predecessor funds to determine which predecessor
         fund, if any, the surviving or new fund most closely resembles. Among
         other factors, funds should compare the various funds' investment
         advisers; investment objectives, policies, and restrictions; expense
         structures and expense ratios; asset size; and portfolio composition.
         These factors are substantially similar to the factors the staff
         considers in determining the accounting survivor of a business
         combination involving investment companies. We believe that, generally,
         the accounting survivor of a business combination for accounting
         purposes, i.e., the fund whose financial statements are carried
         forward, will be the fund whose historical performance may be used by a
         new or surviving fund."

7.   Comment:  In the Pro Forma Statement of Operations, please consider
               changing footnote reference "(d)" to footnote reference "(c") for
               clarification purposes.

     Response: The requested change will be made.

Registration Statement relating to the proposed reorganization of the MFS Mid
Cap Value Portfolio (the "Mid Cap Value Portfolio") into the MFS Value Portfolio
(the "Value Portfolio").

8.   Comment:  The Prospectus/Proxy Statement currently discusses potential tax
               consequences of the portfolio  repositioning  that is expected to
               occur in connection with the reorganization.  Please confirm that
               this disclosure is applicable given the fact that the Funds serve
               as investment options supporting  tax-deferred variable insurance
               contracts. If not applicable, please remove.

     Response: We do not believe that the portfolio repositioning will have
               tax implications for Contract Holders with investments
               allocated to the Funds given the tax-deferred status of the
               variable insurance products through which investments in the
               Funds are made. As a result, all disclosure discussing the
               potential tax implications resulting from the portfolio
               repositioning will be removed from the Prospectus/Proxy
               Statement.

9.  Comment:   Under the caption "Background and Reasons for the Proposed
               Reorganization",  the Prospectus/Proxy Statement currently states
               that the  reorganization  presents an  opportunity  for the Value
               Portfolio to acquire  investment  assets  without the need to pay
               brokerage   commissions  or  other  transaction  costs  that  are
               typically  associated  with the purchase and sale of  securities.
               Please modify this  disclosure  to note that the Value  Portfolio
               will incur brokerage  commissions or other transaction costs with
               respect to the portion of portfolio  securities received from the
               Mid Cap Value  Portfolio that will be  repositioned  by the Value
               Portfolio following the reorganization,  as previously  disclosed
               in the Prospectus/Proxy Statement.

     Response: The first sentence in the fourth paragraph in the section
               entitled "Background and Reasons for the Proposed
               Reorganization" will be revised as follows:

               "The  Board  of  Trustees   considered  that  the  reorganization
               presents  an  opportunity  for the  Value  Portfolio  to  acquire
               investment  assets without the need to pay brokerage  commissions
               or other transaction costs normally  associated with the purchase
               of  securities   other  than  brokerage   commissions  and  other
               transaction   costs   associated  with  any   post-reorganization
               portfolio  repositioning as described in the response to Question
               4, " How  do  the  investment  objectives,  principal  investment
               strategies,  policies  and  restrictions  of the  two  Portfolios
               compare?" in the Synopsis.
