Coogan's Bluff is a promontory near the western shore of the Harlem River in the Washington Heights neighborhood of Upper Manhattan in New York City. Its boundaries extend approximately from 155th Street and the Macombs Dam Bridge viaduct to 160th Street, between Edgecombe Avenue and the river. A deep escarpment descends 175 feet (53 m) from Edgecombe Avenue to the river, creating a sheltered area between the bluff and river known as Coogan's Hollow. From 1890 to 1964, the hollow was home to the Polo Grounds sports stadium.
