Registration Statement on Form F-1

File No. 333-188556

Ladies and Gentlemen:

Pursuant to Rule 461 promulgated under the Securities Act of 1933, as amended, Constellium N.V. (the “Registrant”) hereby requests that the effective date of the Registrant’s Registration Statement on Form F-1 (File No. 333-188556) be accelerated by the U.S. Securities and Exchange Commission (the “Commission”) to 5:00 p.m. EST on May 22, 2013, or as soon as possible thereafter.

In connection with the foregoing request for acceleration of effectiveness, the Registrant hereby acknowledges the following:

• should the Commission or its staff, acting pursuant to delegated authority, declare the filing effective, it does not foreclose the Commission from taking any action with respect to the filing;

• the action of the Commission or the staff, acting pursuant to delegated authority, in declaring the filing effective, does not relieve the Registrant from its full responsibility for the adequacy and accuracy of the disclosure in the filing; and

• the Registrant may not assert staff comments or the declaration of effectiveness as a defense in any proceeding initiated by the Commission or any person under the federal securities laws of the United States.

Please contact Andrew J. Nussbaum at (212) 403-1269 or Karessa L. Cain at (212) 403-1128 of Wachtell, Lipton, Rosen & Katz with any questions you may have concerning this request, and please notify either of them when this request for acceleration has been granted.

Very truly yours,
Constellium N.V.
