Petoskey State Park is a public recreation area covering 303 acres (123 ha) on Lake Michigan in Bear Creek Township, Emmet County, Michigan.

The state park is located three miles (4.8 km) northeast of the city of Petoskey on Little Traverse Bay.

The tannery occupied 180 acres that were eventually divided between Petoskey State Park and the commercial district on U.S. Highway 31.

The Michigan Conservation Commission approved the creation of Petoskey State Park on the old tannery lands—with the potentiality of also purchasing the city's bathing beach for inclusion as well—in June 1961.

[8] The State of Michigan purchased the beach from the City of Petoskey for $150,000 in 1968, took title in 1969, and the first 90 sites in the park's campground opened in June 1970.
