Wisconsin is a U.S. state located in the north-central United States, in the Midwest and Great Lakes regions. It is bordered by Minnesota to the west, Iowa to the southwest, Illinois to the south, Lake Michigan to the east, Michigan to the northeast, and Lake Superior to the north. Wisconsin is the 23rd state by total area and the 20th most populous. The state capital is Madison, and its largest city is Milwaukee, which is located on the western shore of Lake Michigan. The state comprises 72 counties.
Wisconsin's geography is diverse, with the Northern Highland and Western Upland along with a part of the Central Plain occupying the western part of the state and lowlands stretching to the shore of Lake Michigan. Wisconsin is second to Michigan in the length of its Great Lakes coastline.
Wisconsin is known as "America's Dairyland" because it is one of the nation's leading dairy producers, particularly famous for cheese. Manufacturing and tourism are also major contributors to the state's economy.
Wisconsin is bordered by the Montreal River; Lake Superior and Michigan to the north; by Lake Michigan to the east; by Illinois to the south; and by Iowa to the southwest and Minnesota to the northwest. A border dispute with Michigan was settled by two cases, both Wisconsin v. Michigan, in 1934 and 1935. The state's boundaries include the Mississippi River and St. Croix River in the west, and the Menominee River in the northeast.
