Mackinac County is a county in the Upper Peninsula of the U.S. state of Michigan. As of the 2010 census, the population was 11,113.[3] The county seat is St. Ignace.[4] Formerly known as Michilimackinac County, it was organized as one of the first counties of the Michigan Territory in 1818, as it had long been a center of French and British colonial fur trading, a mission, and associated settlement.[1]

The county's name is believed to be shortened from the French term "Michilimackinac," which referred to the Straits of Mackinac area as well as the French settlement at the tip of the lower peninsula.[1] See and compare List of Michigan county name etymologies, List of Michigan counties, and List of abolished U.S. counties.


Michilimackinac County was created on October 26, 1818, by proclamation of territorial governor Lewis Cass. The county originally encompassed the Lower Peninsula of Michigan north of Macomb County and almost the entire present Upper Peninsula. As later counties were settled and organized, they were divided from this territory.

At the time of founding, the county seat was the community of Michilimackinac Island on Michilimackinac Island, later known as Mackinac Island, Michigan. The county was reorganized in 1849 as Mackinac County. In 1882 the county seat was moved from Mackinac Island to St. Ignace, Michigan, founded as a French Jesuit mission village during the colonial years.


  • According to the 2010 census, the county has a total area of 2,100.64 square miles (5,440.6 km2), of which 1,021.57 square miles (2,645.9 km2) (or 48.63%) is land and 1,079.07 square miles (2,794.8 km2) (or 51.37%) is water.[5]

The county board of commissioners controls the budget but has only limited authority to make laws or ordinances. In Michigan, most local government functions — police and fire, building and zoning, tax assessment, street maintenance, etc. — are the responsibility of individual cities and townships.
