Michipicoten Island () in Ontario, Canada, is in the northeastern part of Lake Superior, about 175 km northwest of Sault Ste. Marie and 65 km southwest of Wawa, Ontario. At its closest point to mainland Ontario, the island is about 16 km from the mainland. It falls within the boundaries of Thunder Bay District. The third largest island in Lake Superior, after Isle Royale and St. Ignace Island, Michipicoten Island is 27 km long and 10 km wide at its widest point.

Most of the lands of Michipicoten Island, as well as smaller islands, shoals, and waters which surround it to within 2500 m, were regulated as Michipicoten Island Provincial Park in 1985. Despite attempts to develop a comprehensive park management plan in the early- to mid-2000s, it continues to be administered by Ontario Parks under an interim management statement developed in 1986.

During the spring, summer, and fall, the island is inhabited or regularly visited by the owners of camps located on a small number of private inholdings, commercial fishers, and clients of a commercial outpost camp. It has become a destination for some adventurous kayakers. In the winter, due mainly to reasons of remoteness and difficulty of access, the island is usually uninhabited.

Michipicoten Island has plentiful wildlife (notably beaver, woodland caribou, and birds). It is located in the Great Lakes-St. Lawrence Forest region.{{cite web|url=http://cfs.nrcan.gc.ca/pubwarehouse/pdfs/24040.pdf|title=Forest regions of Canada

The island is made up of ancient lava bedrock related to volcanism of the Midcontinent Rift System and is heavily forested, with over 20 inland lakes. It has a rugged interior, containing east-west aligned ridges with gentle southern slopes and steep northern slopes. The highest point is 298 m above Lake Superior.

A lighthouse was established in 1912 on the eastern end of the island. It was staffed until 1988.

On some old maps, Michipicoten Island is shown as Isle Maurepas, after the French minister of Marine Jean-Frédéric Phélypeaux, Count of Maurepas. The word Michipicoten is an Anglicization of the original Ojibwe word Mishipikwadina, meaning "big bluffs" in Ojibwe, and is a reference to the geography of the nearby Michipicoten River.

Mishipeshu, a powerful creature in the traditional beliefs of some Native American tribes―particularly Anishinaabe tribes, the Odawa, Ojibwe, and Potawatomi, of the Great Lakes region of Canada and the United States―is traditionally said to make his home on Michipicoten Island.

Woodland caribou

Michipicoten Island played host to an indigenous caribou population until the herd's extirpation, as a result of overhunting, in the mid-1800s. In 1981, a lone male caribou was observed on the island; how it arrived there remains unknown. In 1982, additional caribou - one male, three adult females and three female calves - were moved to the island from the Slate Islands by the Ministry of Natural Resources. An additional male was translocated in 1989. From the time of these relocations to 2001, the herd population increased at \lambda=1.18 to arrive at approximately 160 animals in 2001. A population determination performed in 2011 concluded that the herd had grown to 680 animals. At times, the rate of population growth was among the fastest ever recorded for caribou.

In the winter of 2014, four wolves transited to Michipicoten Island. This was facilitated by an ice bridge which had formed between the island and the mainland. The wolf population had more than tripled by the winter of 2016/2017.

The caribou population of Michipicoten Island is scientifically significant because it manifests an opportunity to apply A. T. Bergerud's proposed test to assess the viability of the range hypothesis versus the predation hypothesis for providing a credible explanation for caribou population decline. Adapted to Michipicoten Island, Bergerud's proposed test was two-part: First, the caribou population on Michipicoten Island should increase despite the lack of lichen in the island's Great Lakes/St. Lawrence Forest. This happened, and it indicated that lichen was not a critical requirement in the diet of caribou. Second, after the appearance of wolves, the population of caribou should decline. Should these population trends emerge, it would indicate conclusively that wolf predation, and not a lack of lichen as forwarded by the range hypothesis, was a key factor in the decline of caribou throughout North America.

The caribou population of Michipicoten Island is ecologically significant because it and the Slate Islands caribou population are all that conclusively and verifiably remain of a caribou population which was once found throughout the federally recognized ON6 Lake Superior caribou range.{{cite web|url=https://www.registrelep-sararegistry.gc.ca/virtual_sara/files/plans/rs%5Fcaribou%5Fboreal%5Fcaribou%5F0912%5Fe1.pdf

As of March 2019 all of the remaining caribou and wolves had been moved off the island due to the low remaining population of caribou. A pack of eight of the wolves were translocated to Isle Royale in 2018.
