Hyde Park Corner is between Knightsbridge, Belgravia and Mayfair in London, England. It primarily refers to a major road junction at the southeastern corner of Hyde Park, that was originally planned by architect Decimus Burton. The junction includes a broad green-space roundabout in its centre, which is now the setting for Burton's triumphal Wellington Arch.

Knightsbridge is a residential and retail district in central London, south of Hyde Park. It is identified in the London Plan as one of two international retail centres in London, alongside the West End. Knightsbridge is also the name of the roadway which runs near the south side of Hyde Park from Hyde Park Corner.
