The Robert Moses Causeway is an 8.10-mile (13.04 km)-long parkway in Suffolk County, New York, in the United States. The parkway, originally known as the Captree Causeway, connects West Islip on Long Island to the barrier beach islands, such as Captree Island, Jones Beach Island, and the western tip of Fire Island, to the south. It is designated New York State Route 908J (NY 908J), an unsigned reference route. Except south of NY 27A, the road, like most parkways in New York State, is limited to non-commercial traffic.

The Robert Moses Causeway begins inside Robert Moses State Park, located on the western tip of Fire Island. From here, the highway heads north across the Fire Island Inlet on the Fire Island Inlet Bridge. On the north side of the inlet, the road changes from a two-lane undivided highway into a four-lane undivided highway as it enters Captree State Park and approaches a cloverleaf interchange with Ocean Parkway. The parkway becomes a five-lane divided highway with three northbound lanes and two southbound lanes in the vicinity of the junction.
