Green Park tube station is a London Underground station located on the north side of Green Park itself, on Piccadilly close to its intersection with the pedestrian Queen's Walk. It is in Travelcard Zone 1.

It is between Bond Street and Westminster on the Jubilee Line, Victoria and Oxford Circus on the Victoria Line and Hyde Park Corner and Piccadilly Circus on the Piccadilly Line.

When the station was opened with the rest of the Piccadilly railway on December 15, 1906 it was known as Dover Street; the name was changed when the entrance moved to accommodate new escalators in 1933. The Victoria Line platforms opened on March 7, 1969, and those for the Jubilee Line on May 1, 1979.
