               File No. 333-261594; 811-23762

Dear Ms. Fuller:

        On December 10, 2021, you filed a registration statement on Form N-1A
on behalf of
Fidelity Greenwood Street Trust. We have reviewed the registration statement
and have
provided our comments below. Where a comment is made with regard to disclosure
in one
location, it is applicable to all similar disclosure appearing elsewhere in the
registration
statement. All capitalized terms not otherwise defined herein have the meaning
given to them in
the registration statement.

                                           GENERAL
    1.   We note that material portions of the filing are incomplete at this
time (e.g., fees and
         expenses, financial information, exhibits, etc.). Please complete and
update all
         information that is currently in brackets or missing in the
registration statement,
         including exhibits, in a pre-effective amendment to the registration
statement. We may
         have additional comments on such portions when you complete them in
pre-effective
         amendments, on disclosures made in response to this letter, on
information supplied
         supplementally, or on exhibits added in any pre-effective amendment.

     2. Please include a line item for Acquired Fund Fees and Expenses under
Annual Fund
        Operating Expenses. Please apply this comment and make the necessary

Fidelity Greenwood Street Trust
Page 2

         disclosure for both the Fidelity Global Macro Opportunities Fund and
the Fidelity Risk
         Parity Fund throughout the filing, as applicable.

    3. Please include in the footnote to the table that the Fund must be able
to make
       recoupment to the adviser without exceeding the net expense ratio in
place at the time
       such amounts were waived, and without exceeding its current net expense
ratio. Please
       apply this comment and make the necessary revisions to the disclosure
for both the
       Fidelity Global Macro Opportunities Fund and the Fidelity Risk Parity
Fund throughout
       the filing, as applicable.

Principal Investment Strategies, page 4

    4. We note the use of the word    global    in the name of the Fund. As
such, please
       expressly describe how the Fund will ensure that its investments have
sufficient
       economic ties to a number of countries throughout the world. See
Investment Company
       Names, Investment Company Act Release No. 24828, at n. 42 (Jan. 17,
2001). For
       example, the Fund could include a policy that, under normal market
conditions, it will
       invest significantly (e.g., at least 40% of its assets, unless market
conditions are not
       deemed favorable, in which case the fund would invest at least 30% of
its assets) in
       companies organized or located in multiple countries outside the United
States or doing
       a substantial amount of business in multiple countries outside the
United States.

    5. Please revise the description of the Fund   s principal investment
strategies to explain the
       Fund   s    macro    investing approach and explain how the various
bullets listed are
       consistent with such approach. In addition, to the extent that the Fund
anticipates that
       certain of the strategies listed, or particular kinds of investments
identified, will
       constitute a more significant component than others, please specify this
and revise your
       disclosure accordingly.

    6. Please disclose the method the Fund uses for determining if a country is
an emerging
       market.

    7. Please delete the phrase    the full spectrum    from the third bullet
point on the page or
       expressly describe its meaning in the given context. Please make this
revision to the
       disclosure for both the Fidelity Global Macro Opportunities Fund and the
Fidelity Risk
       Parity Fund throughout the filing, as applicable.

    8. Please revise the fourth bullet on the page to replace the phrase
provide asymmetric
       payoffs driven by market divergence versus secular, cyclical, and
geopolitical trends
       with a plain English description that more clearly explains this
methodology and key
       terminology.

    9. Disclosure for any principal investment related to derivatives should be
tailored
       specifically to how a fund expects to be managed and should address
those strategies
       that the fund expects to be the most important means of achieving its
objectives and that
 Ren  e Fuller

         it anticipates will have a significant effect on its performance.
Disclosure of your
         principal investment strategies and risks should not be generic
associated with each
         derivative type. (See Barry Miller letter to ICI). Please make any
necessary revisions to
         the disclosure for both the Fidelity Global Macro Opportunities Fund
and the Fidelity
         Risk Parity Fund throughout the filing, as applicable.

    10. We note that both the Fidelity Global Macro Opportunities Fund and the
Fidelity Risk
        Parity Fund intend to invest up to 25% of their assets in a
wholly-owned subsidiary
        organized under the laws of the Cayman Islands (the    Subsidiary   )
that invests in
        commodity-linked total return swaps. Please disclose, for each Fund,
that:

                x   The Fund complies with the provisions of the Investment
Company Act
                    governing investment policies (Section 8) and capital
structure and leverage
                    (Section 18) on an aggregate basis with the Subsidiary.

                x   Any investment adviser to the Subsidiary complies with
provisions of the
                    Investment Company Act relating to investment advisory
contracts (Section
                    15) as if it were an investment adviser to the Fund under
Section 2(a)(20) of
                    the Investment Company Act.

                    Please be advised that any investment advisory agreement
between the
                    Subsidiary and its investment adviser is a material
contract that should be
                    included as an exhibit to the registration statement. If
the same person is the
                    adviser to both the Fund and the Subsidiary, then, for
purposes of complying
                    with Section 15(c), the reviews of the Fund   s and the
Subsidiary   s investment
                    advisory agreements may be combined.

                x   The Subsidiary complies with provisions of the Investment
Company Act
                    relating to affiliated transactions and custody (Section
17). Identify the
                    custodian of the Subsidiary, if any.

                x   The Subsidiary and its board of directors will agree to
designate an agent for
                    service of process in the United States.

        In your correspondence, please:

            x   Explain whether the financial statements of the Subsidiary will
be consolidated
                with those of the Funds. If not, please explain why not.

            x   Confirm that: (1) the Subsidiary   s management fee (including
any performance
                fee), if any, will be included in    Management Fees    and the
Subsidiary   s
                expenses will be included in    Other Expenses    in the each
Fund   s prospectus fee
                table; and (2) the Subsidiary and its board of directors will
agree to inspection by
                the staff of the Subsidiary   s books and records, which will
be maintained in
 Ren  e Fuller

               accordance with Section 31 of the Investment Company Act and the
rules
               thereunder.

Principal Investment Risks, page 4

    11. Please ensure that the principal risks identified are sufficiently
correlated to the Fund   s
        principal investment strategies. For example, you have included
disclosure about the
        risks related to small cap investing, but this does not appear to be
consonant with the
        principal investment strategies articulated above. As another example,
you have
        disclosed that the Fund intends to invest in assets in a manner that
provide[s]
        asymmetric payoffs driven by market divergence versus secular,
cyclical, and
        geopolitical trends,    yet you have included a risk factor for growth
investing, which
        appears to be inconsistent with this approach. Please apply this
comment, as applicable,
        to the principal risk disclosure for both the Fidelity Global Macro
Opportunities Fund
        and the Fidelity Risk Parity Fund and revise the filing as necessary.

Fidelity Risk Parity Fund
Principal Investment Strategies, page 10

    12. To the extent that the Fund anticipates that certain of the strategies
listed, or particular
        kinds of investments identified, will constitute a more significant
component than
        others, please specify this and revise your disclosure accordingly here
and elsewhere in
        the filing as necessary.

    13. Please expand on the third bullet point in this section by discussing
the four factors
        identified (i.e., growth, inflation, real rates and liquidity) and
explain how the Fund
        intends to use quantitative analysis to balance these risks. Please
apply this comment
        and make revisions to the Fund   s disclosure throughout the filing as
necessary.

Principal Investment Risks
Foreign and Emerging Markets Risk, page 19

    14. You state that the Adviser will allocate the Fund's assets across
underlying funds and
        derivatives representing a broad range of asset classes, including
frontier markets
        equities. If there are principal risks unique to investing in frontier
markets not otherwise
        addressed by this risk factor, please add risk disclosure as necessary.

    15. Please be advised that our review of the required financial statements
and related
        information cannot be completed until you have included such
information in the
        registration statement by pre-effective amendment. We may have
accounting and
        related comments on such disclosure once it has been provided.
