Charles Carter Comstock (born March 5, 1818) was a Democratic politician who represented the state of Michigan in the United States House of Representatives. Serving as a member of Congress for Michigan’s 5th Congressional District, he held office as a Representative during the Forty-ninth Congress. His tenure in the U.S. House began on December 7, 1885, and concluded on March 3, 1887, encompassing a single term in federal office.

Comstock’s service in Congress marked his principal recorded role in national politics. As a Democratic Representative from Michigan, he participated in the legislative work of the House during a period of post–Civil War and Gilded Age political realignment, though specific committee assignments or legislative initiatives are not documented in the available record. After his term ended in 1887, he left congressional office and is regarded as a former member of the House from Michigan.
