Sunset Park is a neighborhood in the southern section of the New York City borough of Brooklyn, USA. The neighborhood is located south of Greenwood Heights, Brooklyn, Park Slope and Windsor Terrace, separated by the southern borders of the Green-Wood Cemetery, while 65th Street and the Gowanus Expressway / I-278 mark the southern boundary of the community with Bay Ridge. The community extends westward from Borough Park at 9th Avenue, all the way to the piers of Brooklyn's waterfront and the Brooklyn Army Terminal.

There is a namesake city park within the neighborhood, located between 41st and 44th Streets and 5th and 7th Avenues, which is the second highest point in Brooklyn. The hilly terrain of the park affords visitors magnificent views of Downtown Brooklyn and the Brooklyn Bridge, Lower Manhattan and the Statue of Liberty, Staten Island, and New Jersey beyond. The "main drag" of the neighborhood lies along 5th Avenue. The New York City Subway serves the region on the Fourth Avenue Line with stations at 36th Street, 45th Street, 53rd Street and 59th Street. The area is also home to the Jackie Gleason Bus Depot.
