Lake Superior (French: Lac Supérieur) is the largest of the Great Lakes of North America. The lake is shared by the province of Ontario to the north in Canada, the states of Minnesota to the west, Wisconsin and Michigan to the south in the United States. It is generally considered the largest freshwater lake in the world by surface area. It is the world's third-largest freshwater lake by volume and the largest by volume in North America.

The Ojibwe call the lake gichi-gami, meaning "be a great sea." Henry Wadsworth Longfellow wrote the name as "Gitche Gumee" in The Song of Hiawatha, as did Gordon Lightfoot in his song, "The Wreck of the Edmund Fitzgerald". According to other sources the actual Ojibwe name is Ojibwe Gichigami or Anishinaabe Gichigami. The first French explorers approaching the great inland sea by way of the Ottawa River and Lake Huron during the 17th century referred to their discovery as le lac supérieur.
