Fort Snelling State Park is a state park of the U.S. state of Minnesota, at the confluence of the Mississippi and Minnesota rivers. For many centuries, the area of the modern park has been of importance to the Mdewakanton Dakota people who consider it the center of the earth. The state park, which opened in 1962, is named for the historic Fort Snelling, which dates from 1820. The fort structure is maintained and operated by the Minnesota Historical Society. The bulk of the state park preserves the bottomland forest, rivers, and backwater lakes below the river bluffs. Both the state and historic fort structure are part of the Mississippi National River and Recreation Area, a National Park Service site.
