Re: Post-Effective Amendment No. 1284 to the Registration Statement on Form N-1A of BlackRock Funds<sup>SM</sup> (the "Trust") on behalf of its series, BlackRock Mid-Cap Growth Equity Portfolio (the "Fund")

Dear Ms. O'Neal:

On behalf of the Trust, we herewith transmit for filing, under the Securities Act of 1933, as amended (the "Securities Act"), and the Investment Company Act of 1940, as amended (the "1940 Act"), Post-Effective Amendment No. 1284 (the "Amendment") to the Trust's Registration Statement on Form N-1A (the "Registration Statement") on behalf of the Fund.

The Amendment is being filed pursuant to Rule 485(b) under the Securities Act and it is proposed that the Amendment become effective on September 26, 2025.

The Amendment is being filed for the purpose of (i) completing the information required to be provided in the Registration Statement and (ii) making certain other non-material changes which the Fund deemed appropriate.

The Amendment also includes interactive data format risk/return summary information in Inline XBRL that mirrors the risk/return summary information in the Amendment.

We have reviewed the Amendment and represent to the Securities and Exchange Commission that, to our knowledge, such Amendment does not contain disclosure that would render it ineligible to become effective pursuant to Rule 485(b).

Sidley Austin (NY) LLP is a Delaware limited liability partnership doing business as Sidley Austin LLP and practicing in affiliation with other Sidley Austin partnerships.
