Wisconsin is a U.S. state located in the north-central United States, in the Midwest and Great Lakes regions. It is the 23rd largest 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 is divided into 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, especially paper products, information technology (IT), and tourism are also major contributors to the state's economy.
