Adrian is a city in the U.S. state of Michigan and the county seat of Lenawee County. The population was 21,133 at the 2010 census. Adrian lies in Michigan's 7th congressional district.
Adrian is approximately 30 miles (48 km) southwest of Ann Arbor, 30 miles (48 km) southeast of Jackson, and 30 miles (48 km) northwest of Toledo, Ohio. A portion of the city is on the border between Adrian Township and Madison Charter Township, although the city is politically independent of both. The city's urban area extends beyond the city limits into both of those townships as well as into nearby Raisin Township and Palmyra Township.
Adrian is sometimes referred to as "the Maple City" due in part to the many sugar maple and other maple tree species found throughout the city. The Adrian High School sports teams are known as the "Adrian Maples" and several local businesses use maple in their names.
