Re: Responses to Comments on Chemical Financial Corporation

Form 10-K for Fiscal Year Ended December 31, 2012

Filed February 22, 2013

Response dated January 14, 2014

File No. 000-08185

Dear Mr. Nolan:

Chemical Financial Corporation (the “Corporation”) hereby provides the following response in reply to the Staff’s follow-up comment letter dated January 24, 2014 (the “Comment Letter”) in connection with the above-referenced Form 10-K.

For your convenience, your comment in your Comment Letter is set forth below in italicized print immediately prior to the Corporation’s response.

Comment #1:

We note your response to prior comment 1 in our letter dated December 20, 2013. We note from your response that you feel it would be duplicative to disclose nonaccrual TDRs in the TDR section of the Note 4. However, it appears your disclosures on pages 86-87 of the December 31, 2012 10-K do not satisfy the disclosure requirements under ASC 310-10-50-33 & 34 as it appears you have not included nonaccrual TDRs in these disclosures. Please revise future filings to update the tables presented on pages 86-87 in the December 31, 2012 10-K to include all TDRs - performing and accrual, nonperforming but accrual, and nonaccrual - in accordance with ASC 310-10-50-33 & 34. Please provide your proposed disclosures for the periods presented in your response.

Response:

As requested, the disclosures on pages 86-87 of the Corporation’s December 31, 2012 Form 10-K that are applicable to paragraphs 33 and 34 of ASC 310-10-50 will be revised in future filings to include all of the Corporation’s TDRs, including nonaccrual TDRs.

For your reference, attached is an excerpt from a draft of Note 4 - Loans to be included in the Corporation’s December 31, 2013 Form 10-K applicable to the above referenced disclosures. The amounts included for the twelve months ended December 31, 2012 and 2011 have been revised from the Corporation’s December 31, 2012 Form 10-K filed on February 22, 2013 to include nonaccrual TDRs.

The Corporation also notes that the applicable TDR disclosures in the Corporation’s “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in its December 31, 2013 Form 10-K for such prior periods will be revised to conform with the presentation in the footnotes to the financial statements.

The Corporation is available to discuss any of its responses with you at your convenience. Should you have any questions or want to discuss these matters further, please feel free to contact the undersigned by phone at (989) 839-5358, by fax at (989) 633-0416, or by email at Lori.Gwizdala@ChemicalBankMI.com.

Sincerely,

Chemical Financial Corporation
