Mount Clemens is a city in the U.S. state of Michigan. The population was 16,314 at the 2010 census. It is the seat of government of Macomb County.

Mount Clemens was first surveyed in 1795 after the American Revolutionary War by Christian Clemens, who settled there four years later. Clemens and his friend, John Brooks, built a distillery, which attracted workers and customers, helping to settle the area. Brooks and Clemens platted the land, and the town was named after Clemens in 1818. It received a post office in 1821, with John Stockton as the first postmaster. Christian Clemens is buried at Clemens Park, located just north of downtown.
