Battery Park is a 25-acre public park located at the Battery, the southern tip of Manhattan Island in New York City, facing New York Harbor. At the north end of the park is Castle Clinton, the often re-purposed last remnant of the defensive works that inspired the name of the park; Pier A, formerly a fireboat station. At the other end is Battery Gardens restaurant, next to the United States Coast Guard Battery Building. Along the waterfront, ferries depart for the Statue of Liberty and Ellis Island, and there is also a New York Water Taxi stop. The park is also the site of the East Coast Memorial which commemorates U.S. servicemen who died in coastal waters of the western Atlantic Ocean during World War II, and several other memorials.

To the northwest of the park lies Battery Park City, a planned community built on landfill in the 1970s and 80s, which includes Robert F. Wagner Park and the Battery Park City Promenade. Together with Hudson River Park, a system of greenspaces, bikeways and promenades now extend up the Hudson shoreline. A bikeway might be built through the park that will connect the Hudson River and East River parts of the Manhattan Waterfront Greenway. Across State Street to the northeast stands the old U.S. Customs House, now used as a branch of the National Museum of the American Indian and the district U.S. Bankruptcy Court. Peter Minuit Plaza abuts the southeast end of the park, directly in front of the South Ferry Terminal of the Staten Island Ferry.
