55 Central Park West, also known as the Ghostbusters Building, is a 19-floor housing cooperative located in Manhattan, New York City. The building was built in 1929 and designed by the firm Schwartz and Gross. Both the interior and the exterior possess unique architectural features that set the structure apart from its peers. The building is considered a contributing property within the Central Park West Historic District, which is listed on the National Register of Historic Places.
Plans for the building were filed by architectural firm Schwartz and Gross at the behest of Victor Earle and John C. Calhoun, for whom they were working. Earle, and his brother Guyon, had been actively developing the Upper West Side of New York City since the 1910s.
