Lake Superior is located primarily between the United States and Canada.

As the largest of the Great Lakes, Lake Superior forms part of the border between the U.S. state of Minnesota, Wisconsin, and Michigan and the Canadian province of Ontario. This shared boundary makes Lake Superior an important geographic and cultural landmark for both countries, and its waters are managed through cooperative agreements. Lake Superior’s vast surface area and location contribute to its significance in transportation, natural resources, and recreation for both the United States and Canada.
