Green Park is one of the Royal Parks of London.

It lies between London's Hyde Park and St. James's Park. Together with Kensington Gardens these parks form an almost unbroken stretch of parkland reaching from Whitehall to Notting Hill.

By contrast with its neighbours Green Park has no statues, fountains or lake, but consists entirely of wooded meadows. The park is bounded on the south by Constitution Hill, on the east by the pedestrian Queen's Walk, and on the north by Piccadilly. It meets St. James's Park at the Queen Victoria Memorial Gardens, oppsite the entrance to Buckingham Palace.

Green Park tube station is located on Piccadilly near the north end of Queen's Walk.
