Lapeer is a city in the U.S. state of Michigan and is the county seat of Lapeer County. As of the 2000 census, the city population was 9,072. Most of the city was incorporated from land that was formerly in Lapeer Township, though portions were also annexed from Mayfield Township and Elba Township. The city government is politically independent of all three townships. Lapeer is located in southern Michigan, east of Flint, on the Flint River. The name is an Americanization of the French la pierre, which means 'stone'. (See List of Michigan county name etymologies.)
According to the United States Census Bureau, the city has a total area of 5.6 square miles (15 km2), all land. It is considered to be part of the Thumb of Michigan, which in turn is a subregion of the Flint/Tri-Cities.
For the past 16 years, Lapeer has been a Tree City USA, and has many parks throughout the city, including along the riverside. The parks include a 2.2-mile (3.5 km) paved foot path that winds through some of the parks, through wooded areas, and across ponds.
