Lake Huron ((フランス語:Lac Huron)) is one of the five Great Lakes of North America. Hydrologically, it comprises the easterly portion of Lake Michigan–Huron, having the same surface elevation as its westerly counterpart, to which it is connected by the , Straits of Mackinac. It is shared on the east by the Canadian province of Ontario and on the west by the state of Michigan in the United States. The name of the lake is derived from early French explorers who named it for the Huron people inhabiting the region.
