The L'Anse Indian Reservation is the land base of the Keweenaw Bay Indian Community of the Lake Superior Bands of Chippewa Indians (successor apparent of the L’Anse and Ontonagon Bands). It is located primarily in two non-contiguous sections on either side of the Keweenaw Bay in Baraga County in the Upper Peninsula of the U.S. state of Michigan. The largest section lies in northern L'Anse Township and western Arvon Township on the east side of Keweenaw Bay, while the smaller section lies in northern Baraga Township on the west side of Keweenaw Bay. There is also a much smaller (43.07 acre) part of the reservation in northern Chocolay Township in northeastern Marquette County. The total land area of the reservation is 92.132 sq mi (238.622 km²) and there were 3,672 persons residing on its territory as of the 2000 census, of whom more than 69 percent were white people and only 24.4 percent of solely Native American heritage. Most of the village of Baraga and part of the village of L'Anse are on reservation land.
The L’Anse Reservation is both the oldest and largest reservation in Michigan. It was established under the Chippewa Treaty of 1854. The United States Supreme Court has interpreted this treaty as creating permanent homelands for the Chippewa (Ojibwa Anishnaabeg) signatories to the treaty. The Treaty of 1842, which ceded lands to the federal government, was one of the largest land cession agreements ever made between the U.S. federal government and Indian tribes. It includes provisions and stipulations that the Chippewa retain their rights to fish, hunt and gather on these ceded lands.
The L’Anse Reservation consists of 54,000 acres (220 km²) with approximately 14,000 acres (57 km²) owned by the tribal community. Two thirds of the land is held in tribal common ownership and the remaining third is owned by Indians in fee, restricted fee, or allotted lands status. The entire reservation encompasses nearly one third of the area of Baraga County.
The tribe operates two casinos, the Ojibwa I on reservation land in Baranga County, and the Ojibwa II in a residential neighborhood in Chocolay Township. A 2000 settlement with the state requires the latter to be relocated, and the tribe has proposed moving it to the defunct Marquette County Airport.
