Re: Dimensional ETF Trust (the “Trust”) File Nos. 333-239440 and 811-23580 Registration Statement on Form N-1A

Ladies and Gentlemen:

Pursuant to Rule 485(a)(2) under the Securities Act of 1933, as amended (the “1933 Act”), submitted electronically via the EDGAR system, please find enclosed Post-Effective Amendment Nos. 20/24 (the “Amendment”) to the Trust’s Registration Statement on Form N-1A.  The Amendment is being submitted to add one new series of shares, designated as the Dimensional California Municipal Bond ETF (the “Portfolio”), to the Trust.

The Trust intends, prior to the effective date of the Amendment, to file a subsequent post-effective amendment, pursuant to Rule 485(b) under the 1933 Act, for the purposes of: (i) responding to any comments conveyed by the U.S. Securities and Exchange Commission’s staff on the Amendment; and (ii) updating other timely information contained in the prospectus and statement of additional information relating to the Portfolio.

As noted on the facing sheet, the Amendment relates only to the Portfolio, and the Amendment does not affect the prospectuses and statements of additional information of the Trust’s other series of shares.

Please direct questions and comments relating to this filing to me at the above number, or in my absence, to Jana Cresswell at (215) 564-8048.

Sincerely,

/s/ Brian Crowell
