Black Lake is located in Cheboygan and Presque Isle counties in northern lower Michigan, United States.

Black Lake is a summer destination for many families from the suburban Detroit area and from other nearby states as well as residents of the neighboring town of Onaway.

Onaway State Park, at the southeastern end of the lake, offers camping, swimming and fishing.

Its buildings, built during the Great Depression by the Civilian Conservation Corps, have been deemed eligible for inclusion in the National Register of Historic Places.

Since the late 1960s, the United Auto Workers Union has maintained the Walter and May Reuther Family Education Center on the site of a former private estate.
