St. Joseph County is a county located in the U.S. state of Michigan, on the central southern border with Indiana. As of the 2020 United States census, the population was 60,939. The county seat is Centreville.
French colonists in the late 17th century were the first Europeans to explore this territory, and they named the St. Joseph River for the patron saint of New France. This area was not part of the United States until after the American Revolutionary War. After the 1821 Treaty of Chicago was signed, regional tribes of the indigenous peoples ceded much land to the United States, opening the area for American settlement. The county was set off and organized by the Michigan Territory legislature in 1829; it was named for the river.
The area is home to the oldest and largest Amish community in Michigan.
St. Joseph County comprises the Sturgis, MI Micropolitan Statistical Area and is included in the Kalamazoo-Battle Creek-Portage, MI Combined Statistical Area.
