West Brompton is an area of west London, England, that straddles the boundary between the London Borough of Hammersmith and Fulham and Royal Borough of Kensington and Chelsea. The centuries-old boundary was traced by Counter's Creek, now lost beneath the West London Line railway.

The London Borough of Hammersmith and Fulham is a London borough in West London and which also forms part of Inner London. The borough was formed in 1965 from the merger of the former Metropolitan Boroughs of Hammersmith and Fulham. The borough borders Brent to the north, the Royal Borough of Kensington and Chelsea to the east, Wandsworth to the south, Richmond upon Thames to the south west, and Hounslow and Ealing to the west.
