Lake Superior ( ) is the largest of the five traditionally-demarcated Great Lakes of North America. It is bounded to the north by the Canadian province of Ontario and the U.S. state of Minnesota, and to the south by the U.S. states of Wisconsin and Michigan. It is the largest freshwater lake in the world by surface area if Lake Huron and Lake Michigan are considered to be two lakes. It is the world's third-largest freshwater lake by volume.
