Fort Wilkins Historic State Park is a historical park operated by the U.S. state of Michigan at Copper Harbor, Michigan. It was placed on the National Register of Historic Places in 1970, and is a "Cooperating Site" of the Keweenaw National Historical Park. Copper Harbor is located at the northern tip of the Keweenaw Peninsula, bordering Lake Superior. It is one of the best natural harbors in Keweenaw County and was a quick focus of attention after copper was discovered on the peninsula in the 1830s.
