Van Cortlandt Park is a 1,146-acre (464 ha) park located in the borough of the Bronx in New York City. It is the third largest park in New York City, behind Pelham Bay Park and Staten Island Greenbelt. The park was named for Stephanus Van Cortlandt, who was the first native-born mayor of New York, and the Van Cortlandt family, which was prominent in the area during the Dutch and English colonial periods. Contained within the Park is the Van Cortlandt House Museum, the oldest building in the Bronx.
