 Re: Hartford Funds Exchange-Traded Trust (the “Registrant”)
(SEC File Nos. 333-215165 and 811-23222)

Dear Ms. O’Neal:

We are writing in response
to comments you provided telephonically to Alice Pellegrino, Alexander Karampatsos and me on January 23, 2020 with respect to the
Registrant’s Post-Effective Amendment No. 22 filed on December 6, 2019, relating to Hartford Core Bond ETF (the “Fund”),
a new series of the Registrant. On behalf of the Registrant, we have reproduced your comments below and provided the Fund’s
responses immediately thereafter. Capitalized terms have the meanings attributed to such terms in the Post-Effective Amendment.

1.
    Comment: Please provide supplementally
a completed Annual Fund Operating Expenses table and Expense Example for the Fund.

 Response: The completed Annual Fund Operating Expenses table and Expense Example for
the Fund are attached as Appendix I.

2.
    Comment: Please confirm supplementally
whether the Fund may invest in securities rated below investment grade. If so, please consider adding risk disclosure regarding
investments in securities rated below investment grade.

 Response: The Registrant confirms that the Fund may invest in securities rated below
investment grade, but investing in securities rated below investment grade is not anticipated to be part of the Fund’s principal
investment strategy and is not expected to represent a significant portion of the Fund’s portfolio (generally 5% or less).

    Accordingly, the Registrant does not believe that investing in “securities rated below investment grade” is a principal
or additional risk of the Fund. However, the Registrant respectfully notes that the “Investment Risks – High Yield
Investments (‘Junk Bonds’)” section of the SAI discloses the risks associated with investing in securities rated
below investment grade. The Registrant does not believe any changes are necessary.

3.
    Comment: Please confirm supplementally
whether the Fund may invest in asset-backed and mortgage-backed securities.

 Response: The Registrant confirms that the Fund may invest in asset-backed and mortgage-backed
securities. The Registrant respectfully notes that the Fund’s Principal Investment Strategy section discloses that the Fund
may invest in “asset-backed and mortgage-related securities, including collateralized mortgage and loan obligations”
and that “Mortgage Related- and Asset-Backed Securities Risk” is disclosed as a principal risk of the Fund.

4.
    Comment: In the Fund’s Principal
Investment Strategy section please identify the Fund’s benchmark and disclose the duration of the Fund’s benchmark.

 Response: The Registrant confirms that it will revise the disclosure consistent with
this comment.

5.
    Comment: Please confirm supplementally
that the Fund or its adviser(s) have the records necessary to support the calculation of the performance of the Core Bond Broad
Composite as required by Rule 204-2(a)(16) under the Investment Advisers Act of 1940.

 Response: The Registrant confirms that Wellington Management, the Fund’s sub-adviser,
has the records necessary to support the calculation of the composite performance as required by Rule 204-2(a)(16) under the Investment
Advisers Act.

6.
    Comment: Please confirm supplementally
whether the returns of the Core Bond Broad Composite reflect any sales charges.

 Response: The Registrant confirms that neither the Fund nor any of the accounts in
the Core Bond Broad Composite are subject to any sales charges. Accordingly, the returns of the Core Bond Broad Composite do not
reflect any sales charges.

Should you
have any questions, please feel free to contact me at (202) 261-3464.

Sincerely,

/s/ Adam T. Teufel
