Tobay Beach is a restricted access recreational beach located in the middle of Jones Beach Island, a barrier island off the South Shore of Long Island, New York in Nassau County, New York within the Massapequa 11758 Zipcode. Its name is an acronym for the Town of Oyster Bay, which owns and manages the beach. Residents of the town are allowed entry, with limited access for non-residents.
Access to the beach is via the Ocean Parkway. Tobay Beach is far east of Jones Beach State Park and just west of West Gilgo Beach across the Nassau-Suffolk County line.
It contains four pavilions, five food stands, surfing and soft boarding area, and a picnic area. There is also a 150-slip marina. The town has been trying to stabilize the dunes against erosion since 1989.
