Named after Wimbledon, though the station stands on Merton High Street.
'Wimbledon' probably goes back to a man's name – Wynnman has been suggested – and 'don', a hill. It was written Wimbedounyng in a charter of 967. The station was planned as Merton Grove; for geographical accuracy, maps showed it as South Wimbledon (Merton) from 1928 until the early 1950s.
