There are eight total U.S. states that border the Great Lakes, which are Wisconsin, Pennsylvania, Ohio, New York, Minnesota, Michigan, Illinois and Indiana. There are also two Canadian provinces that border the Great Lakes, and these are Quebec and Ontario.
The St. Lawrence River, which is located on the Quebec border, is an important part of the Great Lakes' structure. The Great Lakes consist of six total bodies of water that are named Lake Superior, Lake Michigan, Lake Huron, Lake Ontario, Lake Erie and the Georgian Bay. The states and provinces that border these bodies of water form a unique economic and historical region, which is often referred to as the Great Lakes Megalopolis.
