Mackinac County (/ˈmækənɔː/ MAK-ə-naw, locally /ˈmækənə/ MAK-ə-nə) is a county in the Upper Peninsula of the U.S. state of Michigan. As of the 2020 census, the population was 10,834.^[3] The county seat is St. Ignace.^[4] Formerly known as Michilimackinac County, in 1818 it was one of the first counties of the Michigan Territory, as it had long been a center of French and British colonial fur trading, a Catholic church and Protestant mission, and associated settlement.^[1]

The county's name is shortened from "Michilimackinac", which referred to the Straits of Mackinac area as well as the French settlement at the tip of the lower peninsula.^[1] Mackinac County is one of two U.S. counties to feature shorelines on two Great Lakes, being Lake Huron and Lake Michigan (the other county being neighboring Chippewa County).
