Floyd Bennett Field is an airfield in the Marine Park neighborhood of southeast Brooklyn in New York City, along the shore of Jamaica Bay. The airport originally hosted commercial and general aviation traffic before being used as a naval air station. Floyd Bennett Field is currently part of the Gateway National Recreation Area's Jamaica Bay Unit, and is managed by the National Park Service (NPS). While no longer used as an operational commercial, military, or general aviation airfield, a section is still used as a helicopter base by the New York City Police Department (NYPD), and one runway is reserved for hobbyists flying radio-controlled aircraft.

Floyd Bennett Field was created by connecting Barren Island and several smaller islands to the rest of Brooklyn by filling the channels between them with sand pumped from the bottom of Jamaica Bay. The airport was named after Floyd Bennett, a noted aviator who piloted the first plane to fly over the North Pole and had visualized an airport at Barren Island before dying in 1928; construction on Floyd Bennett Field started the same year. The airport was dedicated on June 26, 1930, and officially opened to commercial flights on May 23, 1931. Despite the exceptional quality of its facilities, Floyd Bennett Field never received much commercial traffic, and it was used instead for general aviation. During the interwar period, dozens of aviation records were set by aviators flying to or from Floyd Bennett Field.

Starting in the 1930s, the United States Coast Guard and United States Navy occupied part of the airport.
