The Osborne, also known as the Osborne Apartments or 205 West 57th Street, is an apartment building at Seventh Avenue and 57th Street in Midtown Manhattan in New York City. The original portion of the Osborne was designed by James Edward Ware and constructed from 1883 to 1885. An annex to the west, designed by Alfred S. G. Taylor and Julian Clarence Levi, was constructed in 1906. The Osborne is one of the oldest extant luxury apartment buildings in New York City.

57th Street is a broad thoroughfare in the New York City borough of Manhattan, one of the major two-way, east-west streets in the borough's grid. As with Manhattan's other "crosstown" streets, it is divided into its east and west sections at Fifth Avenue. The street runs from a small park overlooking the East River in the east to the West Side Highway along the Hudson River in the west. 57th Street runs through the neighborhoods of Sutton Place, Midtown Manhattan, and Hell's Kitchen from east to west.
