Bois Blanc Township is a civil township of Mackinac County in the U.S. state of Michigan. As of the 2010 census, the population was 95. The township occupies Bois Blanc Island, as well as some smaller outlying islands within Lake Huron. The nearby Round Island is administered by the city of Mackinac Island.

The township is served by Bois Blanc Pines School District, which is the smallest school district in terms of enrollment in the state of Michigan and among the nation. The district had an enrollment of four students for the 2021–22 school year.[4]

"Bois Blanc" is French for "white wood".[9] The name is commonly thought to be a reference to either: (a) the paper birch, or more likely (b) the basswood, called "bois blanc" in other contexts.[10] The basswood's white underbark was extensively used by Native Americans and French-speaking fur traders for cordage, including the sewing up of canoes and the manufacture of webbing for snowshoes.

Bois Blanc was ceded by the local Anishinaabe (Chippewa) to the U.S. federal government with the Treaty of Greenville in 1795.[11] After extensive use as a source of kilned lime and firewood for Mackinac Island and other local frontier settlements, Bois Blanc was settled in the late 1800s as a summer resort community. The Bois Blanc Light lighthouse (1867) survives on the northern shore of the island; it is no longer in service as a lighthouse and is not open to the public.


There sparsely populated township contains no paved roads. A maintained county road extends from the island's northeast corner to the far western tip. There are numerous unmaintained roads and trails. Commercial access to the island is provided by ferry connections with Cheboygan through a dock at Pointe aux Pins. The township is also served by a paved airstrip, Bois Blanc Island Airport, in the interior of the island with facilities for private planes.


According to the United States Census Bureau, the township has a total area of 48.72 square miles (126.18 km2), of which 35.11 square miles (90.93 km2) is land and 13.61 square miles (35.25 km2) (27.94%) is water.

The township consists of Bois Blanc Island in Lake Huron. Bois Blanc Island is southeast of Mackinac Island and due north of Cheboygan. Round Island is a smaller uninhabited island between Bois Blanc and Mackinac Island and is part of the Hiawatha National Forest. That island is administered by the city of Mackinac Island. Bois Blanc Township is one of only seven municipalities in the state of Michigan to consist entirely of islands, including Grosse Ile Township, Drummond Township, St. James Township, Mackinac Island, Peaine Township, and Sugar Island Township.

The township should not be confused with the Canadian Bois Blanc Island, which is part of Essex County, Ontario much further south in the Detroit River. That island is also nicknamed "Boblo."
