Form 8-K filed February 20, 2014

Response dated May 19, 2014

File No. 001-13718

Dear Mr. Spirgel and Ms. Davis,

We greatly appreciate your further time and consideration earlier today to discuss certain responses of MDC Partners Inc. (the “Company”) to the comments of the Staff of the Division of Corporation Finance, as set forth in our prior letter to the Staff dated June 26, 2014.

As discussed, in responding to Comment 7 of the comment letter previously received from the Staff, the Company will promptly revise all references to “Free Cash Flows” (as presented in the Company’s recent earnings releases). Specifically, in future earnings releases the Company will use the term “Adjusted EBITDA Available for General Capital Purposes” in place of “Free Cash Flow.” In addition, as discussed with you on today’s call, the Company will present a detailed definition and complete reconciliation of this non-GAAP measure to Net Income under GAAP.

*                                   *                                  *                                  *                                  *

The Company hereby acknowledges the following:

· the Company is responsible for the adequacy and accuracy of the disclosure in its filings;

· Staff comments or changes to disclosure in response to Staff comments do not foreclose the Commission from taking any action with respect to the filings; and

· the Company may not assert Staff comments as a defense in any proceeding initiated by the Commission or any person under the federal securities laws of the United States.

Please direct any questions concerning the above responses to the undersigned (telephone: (646) 429-1805; fax: (212) 937-4365).

Very truly yours,

/s/ David Doft
