Lakeville is an exurb of Minneapolis-Saint Paul, and the largest city in Dakota County, Minnesota, United States. It is about 20 miles (32 km) south of both downtown Minneapolis and downtown St. Paul along Interstate 35. Lakeville was once a flourishing milling center; its agriculture industry and other major industries are still in operation. It is one of the fastest-growing cities in the Twin Cities area. The population was 69,490 at the 2020 census, making it Minnesota's tenth-most populous city. Lakeville first became notable in 1910 when Marion Savage built the Dan Patch Railroad Line to serve his Antlers Amusement Park. While many of Lakeville's workers commute to Minneapolis, St. Paul, and more central suburbs like Bloomington, Lakeville has had major industry since the 1960s—including the Airlake Industrial Park, which is served by Airlake Airport, a regional reliever airport.
