Lake Carlos State Park is a state park about 10 miles north of Alexandria, Minnesota, USA. The park was established in 1937 to provide a public recreational facility in one of Minnesota's summer resort centers, and attracts tourists from Minnesota and bordering states. Five buildings in the park, constructed by the Works Progress Administration in the Rustic Style, are included within the National Register of Historic Places. These include the Mess Hall and Crafts Building within the group camp area, as well as the water tower, sanitation building, and bath house within the public use area.
