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).

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.

On April 1, 1840, areas in the Lower Peninsula were laid off to create 30 new counites.^[5] By 1841, the County of Michilimackinac was confined to the Upper Peninsula and its nearby islands, bordering Chippewa and Menominee counties.^[6]

On March 9, 1843, Michigan further divided the Upper Peninsula into six counties. At this time, the County of Michilimackinac more closely resembled its modern configuration, including only a portion of the Upper Peninsula closest to the Straits of Mackinac, plus several islands.^[7]

At the time of founding, the county seat was the community of Michilimackinac Island on Michilimackinac Island, later known as Mackinac Island, Michigan. This has been an important center for fur trading before the 1830s, when European demand declined. The county was organized in 1849 as Mackinac County. In 1882 the county seat was moved from Mackinac Island to St. Ignace, Michigan, which had been founded as a French Jesuit mission village during the colonial years.

Mackinac County is home to the Mackinac Bands of Chippewa and Ottawa Indians, a Native American state recognized tribe located in St. Ignace.

According to the U.S. Census Bureau, the county has a total area of 2,101 square miles (5,440 km²), of which 1,022 square miles (2,650 km²) is land and 1,079 square miles (2,790 km²) (51%) is water.^[8] Mackinac County lies at the boundary of Lake Huron and Lake Michigan.

St. Ignace is the northern terminus of the Mackinac Bridge. Mackinac Island is within the county.

Due to its sparse population, the county has no weather stations.

The 2010 United States census reported that Mackinac County had a population of 11,113, a decrease of 830 (-6.9%) from the 2000 census.^[15] In 2010 there were 5,024 households and 3,219 families in the county. The population density was 11 per square mile (4.2/km²). There were 11,010 housing units at an average density of 11 per square mile (4.2/km²)>). Racially, 76.5% of the population were White, 17.3% Native American, 0.5% Black or African American, 0.2% Asian, 0.2% of some other race and 5.3% of two or more races; 1.1% were Hispanic or Latino (of any race). Culturally, 18.5% were of German, 8.8% English, 8.0% French, French Canadian or Cajun, 7.6% Irish and 5.1% Polish ancestry.^[16] By the 2020 census, its population was 10,834.^[3]

The average household size was 2.19 and the average family size was 2.7. Among them, 18.7% of the population were under the age of 18, 5.5% from 18 to 24, 19.3% from 25 to 44, 34.0% from 45 to 64, and 22.3% who were 65 years of age or older. The median age was 49 years.

Mackinac County is reliably Republican. Since the 1964 landslide of Lyndon B. Johnson, it has only supported a Democrat twice. Bill Clinton won the county in his 1992 and 1996 victories; the latter remains the last time a Democratic presidential candidate has won the county.

The county government operates the jail, maintains rural roads, operates the major local courts, keeps files of deeds and mortgages, maintains vital records, administers public health regulations, and participates with the state in the provision of welfare and other social services. 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.
