Port Crescent State Park is a public recreation area on Lake Huron 5miles southwest of Port Austin in Huron County at the tip of The Thumb of Michigan. The state park covers along state route M-25 in Hume Township. The park occupies the site of Port Crescent, a ghost town which once stood at the mouth of the Pinnebog River.

The park's first 124 acres were purchased by the state in 1956. One of the last visible remnants of the vanished town of Port Crescent, the 120-foot-tall Pack & Woods Sawmill chimney, was razed in 1961, despite the objections of residents who felt the loss of the local landmark. The park was expanded with the purchase of an additional 455 acres in 1977.
The state park offers swimming, picnicking, canoeing, fishing, of hiking trails, cross-country skiing, and a 142-site campground and cabin.
