The Waterloo-Pinckney Trail is a 38-mile-long hiking trail which runs through Waterloo State Recreation Area and Pinckney Recreation Area in southeastern Michigan, United States.

The trail travels through glacial features such as eskers and kettle lakes as well as swamps and open meadows remaining from abandoned farmlands.

The trail has several nearby campgrounds allowing it to be hiked as a 2, 3 or 4 day trip.

Side trails to the campgrounds make the entire trip 40.5 miles (65.2 km).
