Fort Michilimackinac was an 18th-century French, and later British, fort and trading post at the Straits of Mackinac; it was built on the northern tip of the lower peninsula of the present-day state of Michigan in the United States. Built around 1715, and abandoned in 1783, it was located along the Straits, which connect Lake Huron and Lake Michigan of the Great Lakes of North America.

The Straits of Mackinac are the short waterways between the U.S. state of Michigan's Upper and Lower Peninsulas, traversed by the Mackinac Bridge. The main strait is 3+1⁄2 miles wide with a maximum depth of 295 feet, and connects the Great Lakes of Lake Michigan and Lake Huron. Given the large size and configuration of the straits, hydrologically, the two connected lakes are one body of water, studied as Lake Michigan–Huron. Historically, the native Odawa people called the region around the Straits Michilimackinac.
