Indian Key Historic State Park is an island within the Florida State Park system, located just a few hundred yards southeast of U.S. 1 within the Florida Keys off of the Hawk Channel passage. The island was home to the town of Indian Key, Florida, in the middle of the 19th century but is now an uninhabited ghost town. It is frequently visited by tourists and is the subject of an archaeological project to uncover the historic building foundations. The park was listed on the National Register of Historic Places in 1972.
