Jones Beach Island is a barrier island off the southern coast of Long Island in the U.S. state of New York. It is separated from Long Island by South Oyster Bay. The island straddles the county line between Nassau and Suffolk counties.
The southern side of the island is known for its excellent beaches that face the open Atlantic Ocean. Jones Beach State Park, on the western tip of the island is a popular summer recreational destination for the New York City area.
It is accessible from Long Island on its western end by the Meadowbrook Parkway to Merrick, New York and the Wantagh Parkway to Wantagh, New York. Its eastern end is linked to Babylon (village), New York by the Robert Moses Causeway. The Ocean Parkway connects all three causeways and runs the length of the island.
