• St James's Park is a 23-hectare (57-acre) park in the City of Westminster, central London. It is at the southernmost tip of the St James's area, which was named after a leper hospital dedicated to St James the Less. It is the most easterly of a near-continuous chain of parks that includes (moving westward) Green Park, Hyde Park, and Kensington Gardens.

The park is bounded by Buckingham Palace to the west, the Mall to the north, Horse Guards to the east, and Birdcage Walk to the south. It meets Green Park at Queen's Gardens with the Victoria Memorial at its center, opposite the entrance to Buckingham Palace. St James's Palace is on the opposite side of The Mall.
