The Great South Bay (actually a lagoon) is an arm of the Atlantic Ocean, approximately 45 mi (72 km) long, forming a large natural harbor on the southern side of Long Island in the U.S. state of New York. It is protected from the open ocean by Fire Island, a barrier island approximately 30 mi (48 km) long, as well as the eastern end of Jones Beach Island. The bay is accessible from the ocean through the narrow Fire Island Inlet between the western tip of Fire Island and the eastern tip of Jones Beach Island. The bay connects to South Oyster Bay on its western end.
