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.
