St James's Park is a 23-hectare park in the City of Westminster, central London. The park lies at the southernmost tip of the St James's area, which was named after a leper hospital dedicated to St James the Less. The park is the most easterly of a near-continuous chain of parks that comprises 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 centre, opposite the entrance to Buckingham Palace. St James's Palace is on the opposite side of The Mall. The closest London Underground stations are St James's Park, Green Park, Victoria, and Westminster.
The park is Grade I listed on the Register of Historic Parks and Gardens.
