Michipicoten Island is an island in Ontario, Canada, in the northeastern part of Lake Superior, approximately 175 kilometres (109 mi) northwest of Sault Ste. Marie and 65 kilometres (40 mi) southwest of Wawa, Ontario. It falls within the boundaries of Thunder Bay District, not Algoma District.
The third largest island in Lake Superior, Michipicoten Island is 27 kilometres (17 mi) long and 10 kilometres (6.2 mi) wide at its widest point. Uninhabited by humans and with plentiful wildlife (notably beaver, woodland caribou, and birds), it has become a destination for some adventurous kayakers. At its closest point to mainland Ontario, the island is located about 16 kilometres (9.9 mi) from land.
The entire island is administered by Ontario Parks as Michipicoten Island Provincial Park. The island is made up of ancient lava bedrock related to volcanism of the Midcontinent Rift System and is heavily forested, with several inland lakes.
A lighthouse was established in 1912 on the eastern end of the island.
