National park system unit in New York, United States

Fire Island National Seashore (FINS) is a United States National Seashore that protects a 26 mile (42 km) section of Fire Island, an approximately 30 mile (48 km) long and 0.5 mile (1 km) wide barrier island separated from Long Island by the Great South Bay. The island is part of New York State's Suffolk County and the Outer Barrier. There are 17 private communities within the boundaries of Fire Island National Seashore including Saltaire, Fire Island Pines, and Ocean Beach. Only two bridges lead to Fire Island and the national seashore and there are no public roads within the seashore itself. The Robert Moses Causeway leads to Robert Moses State Park on the western end of Fire Island while the William Floyd Parkway leads to the eastern end of the island. The seashore can also be accessed by private boat or by ferry from the communities of Patchogue, Sayville, and Bay Shore on Long Island. Fire Island National Seashore was established as a unit of the National Park Service on September 11, 1964. A separate unit of Fire Island National Seashore located on Long Island protects the home and estate of William Floyd, an American Revolutionary War general and a signer of the Declaration of Independence. The William Floyd House is listed on the National Register of Historic Places and is located in Mastic Beach, New York.

The Fire Island Light is located near the western end of the seashore near Robert Moses State Park. Lighthouse Beach is a beach at the extreme west end of the seashore, just east of Robert Moses State Park. Since 2013, a nudity ban has been enforced at this former clothing optional beach. Sailor's Haven is home to a popular 1.5 mile (2 km) boardwalk trail through an area known as the Sunken Forest as well as a visitor center, general store, and a public marina. Otis Pike Fire Island High Dune Wilderness, located on the eastern end of Fire Island, is the only federally designated U. S. Wilderness Area in New York State.

The Otis Pike Fire Island High Dune Wilderness, also known as Fire Island Wilderness, is a wilderness area on Fire Island. It is approximately 7 mile (11 km) long and located on the eastern side of Fire Island. The United States Congress designated the Otis Pike High Dune Wilderness Area in 1980. The wilderness area is named for former New York Congressman Otis G. Pike, who co sponsored the bill which created the Fire Island National Seashore and worked hard to secure public support and the legislation's passage through Congress to establish the new national park. It is the only federally designated wilderness area in New York State and one of the smallest wilderness areas managed by the National Park Service. Access to the Otis G. Pike Wilderness can be obtained either from Watch Hill (which is accessible seasonally by ferry or private boat) or Smith Point County Park, accessible year round by car or bus. The Wilderness Visitor Center is located on the eastern edge of the wilderness, adjacent to Smith Point County Park. Privately owned Bellport Beach is located near the central area of the wilderness.

Old Inlet, just west of Smith Point County Park in the wilderness, has been the site of breaches of Fire Island causing the Atlantic Ocean to join with the Great South Bay. The most recent breach occurred during the high tides associated with Hurricane Sandy in October 2012. The breach was 276 feet (84 m) wide on the Atlantic side a week after the storm and 856 feet (261 m) wide on April 5, 2013. National Park Service officials have been debating whether to take action to close the breach. Contingency plans put in place to manage breaches within the wilderness area called for initial monitoring of the breach; as of 2014, the breach has stabilized and monitoring continues. along with repopulation of fish and clams that had been absent from the bay for decades due to pollution. A draft plan for action was scheduled to be released in summer 2016. The National Park Service ultimately decided not to take any action and instead let the landscape evolve naturally. By summer 2022, the breach was filling with sand, having shrunk tenfold to less than 100 feet wide.
