Re: Dune Acquisition Corporation II
Registration Statement on Form S-1
Filed March 7, 2025
File No. 333-285639

Dear Messrs. Holt and Link:

On behalf of Dune Acquisition Corporation II, a
Cayman Islands company (the “”), we hereby transmit the Company’s response to the comment letter received
from the staff (the “”) of the U.S. Securities and Exchange Commission (the “”),
on March 21, 2025, regarding the Registration Statement on Form S-1 filed with the Commission on March 7, 2025.

For the Staff’s convenience, we have repeated
below the Staff’s comments in bold and have followed each comment with the Company’s response.

| 1. | Regarding your new disclosures about the NMSI private placement warrants, we note that the warrant agreement does not contain the         
 provision requiring the separate consent of a majority of NMSI holders to approve any forfeiture, transfer, exchange or amendment of such 
 warrants in connection with a business combination. Please advise or reconcile. Please also address whether such approval, if withheld,   
 may impact your ability to complete a business combination. Revise similar disclosures where they appear throughout the prospectus.       |

In response to the Staff’s comment, we have revised
the warrant agreement to include such provision and have revised the registration statement to clarify that such approval, if withheld,
may impact the Company’s ability to complete a business combination.

| 2. | Clarify when the NMSI private placement warrants will be purchased by the non-managing sponsor investors. Disclosure on the cover           
 page states that this will take place simultaneously with the closing of the offering, however, disclosure on page 1 states that the NMSI   
 private placement warrants will be distributed upon closing of your initial business combination. Also clarify whether the non-managing     
 sponsor members will hold the NMSI private placement warrants directly, or whether they will be held indirectly through the sponsor. For    
 example, disclosure on the cover page states that the NMSI private placement
