Prior Lake is a city southwest of downtown Minneapolis seated next to Savage and Shakopee in Scott County in the U.S. state of Minnesota. Surrounding the shores of Lower and Upper Prior Lake, the city lies south of the Minnesota River in an area known as South of the River and establishes the urban fringe of the south-southwest portion of Minneapolis-St. Paul, the sixteenth largest metropolitan area in the United States. The population of Prior Lake was 22,796 at the 2010 census.
Prior Lake was first incorporated as a village in 1891. Prior Lake is one of the oldest cities in the south metro area. The city's modern rapid growth is due in part to the ease of access for commuters, the rest of the region, via the upgraded State Highway 13.
