No Name Key is an island in the lower Florida Keys in the United States. It is 3 miles (4.8 km) from US 1 and sparsely populated, with only 43 homes. It is only about 1,140 acres (460 hectares) in comparison to its larger neighbor, Big Pine Key, which lies about half a mile (800 m) to its west. It is accessible by a concrete bridge from Big Pine Key and was the terminus of a car ferry that existed before the present Overseas Highway was built on the remains of Flagler's Overseas Railroad.
