Dear Mr. O’Connor:

Per your request, please find below our responses on behalf of Natixis Funds Trust II (the “Trust”) to your comments on Post-Effective Amendment No. 133 relating to the registration of shares of the Delafield Select Fund (the “Fund”), filed on April 11, 2008. You provided your comments in a telephone call on June 4, 2008. Each one of your comments is repeated below, followed by the Trust’s response.

Principal Investment Strategies

1. Comment. Is there a limit on the amount that may be invested in securities issued as part of privately negotiated transactions between an issuer and one or more purchasers?

Response. Currently, there is no explicit percentage limit on the amount that may be invested in securities issued as part of privately negotiated transactions between an issuer and one or more purchasers. The Predecessor Fund does not currently invest in such securities. The Fund does not currently intend to invest in such securities, and disclosure regarding such securities and other non-principal investment strategies has been moved to the Fund’s Statement of Additional Information.

Fund Fees & Expenses

2. Comment. Provide the maximum sales charge (load) imposed on purchases (as a percentage of offering price) for Class A shares.

3. Comment. Will the subcaption “Acquired Fund Fees and Expenses” be included in the Annual Fund Operating Expenses table on page 7 of the Class AC prospectus?

Response. The Fund does not intend to invest in any securities of “Acquired Funds.” Therefore, the subcaption “Acquired Fund Fees and Expenses” has not been included in the Annual Fund Operating Expenses table.

More About Risk

4. Comment. To what extent does the Fund intend to invest in derivative securities?

Response. The Fund does not currently expect to invest in derivative securities to a significant extent.

Securities Lending

5. Comment. When the Fund lends its securities, does it give up its voting rights on such securities?

Response. The Fund does not generally retain voting rights when securities are out on loan; however, the Fund retains the ability to recall securities on loan in order to vote them when the Adviser believes that doing so is appropriate under the circumstances.
