Brooklyn Bridge Park is an 85-acre (34 ha) park on the Brooklyn side of the East River in New York City. Designed by landscape architecture firm Michael Van Valkenburgh Associates, the park is located on a 1.3-mile (2.1 km) plot of land from Atlantic Avenue in the south, under the Brooklyn Heights Promenade and past the Brooklyn Bridge, to Jay Street north of the Manhattan Bridge. From north to south, the park includes the preexisting Empire–Fulton Ferry and Main Street Parks; the historic Fulton Ferry Landing; and Piers 1–6, which contain various playgrounds and residential developments. The park also includes Empire Stores and the Tobacco Warehouse, two 19th-century structures, and is a part of the Brooklyn Waterfront Greenway, a series of parks and bike paths around Brooklyn.

The East River is a saltwater tidal estuary or strait in New York City. The waterway, which is actually not a river despite its name, connects Upper New York Bay on its south end to Long Island Sound on its north end. It separates Long Island, with the boroughs of Brooklyn and Queens, from Manhattan Island, and from the Bronx on the North American mainland.
