The Fire Island Lighthouse is a well-known landmark on the western end of Fire Island in the Great South Bay. Located within the Fire Island National Seashore and adjacent to the Robert Moses State Park, the lighthouse was originally built in 1826 and later replaced by a taller structure in 1858. It then served continuously as a navigating beacon until 1974 when it was replaced by a small flash tube placed at the top of the Robert Moses water tower.

Standing at 168 feet tall with 192 steps from the bottom to the top, the Fire Island Lighthouse flashes every 7.5 seconds and its light is visible for 24 miles. The lighthouse, operated and maintained by the Fire Island Lighthouse Preservation Society, is listed on the National Register of Historic Places. The Fire Island Lighthouse can be reached by a short walk from the Robert Moses State Park and is open to the public – visitors can enjoy tower tours for a small concession fee.
