Rockaway Inlet is a strait connecting Jamaica Bay, wholly within New York City, with the Atlantic Ocean.
It separates the Rockaway Peninsula in Queens from the Floyd Bennett Field (formerly Barren Island) in Brooklyn.
It is the entrance to Jamaica Bay, and most of the inlet is within the boundary of Gateway National Recreation Area.
Its entrance is marked by a light on a jetty extending southward from Rockaway Point.
In 1968 a light failed and the tanker Mary A. Whalen ran aground, resulting in a case entitled United States v. Reliable Transfer Co. about dividing damage payments.
