Warren Island State Park is state-owned island and public recreation area on Penobscot Bay in the town of Islesboro, Waldo County, Maine, United States. The 70-acre (28 ha) state park sits about ½-mile from Islesboro Island and 3 miles (4.8 km) offshore from the mainland at Lincolnville. The island was acquired by the state of Maine for one dollar in 1959. Hiking trails, campsites, and open-faced shelters are found on the island; a pier allows access by private boat.
