The Wimbledon effect (Japanese: ウィンブルドン現象, rōmaji: "Uinburudon Genshō", literally "Wimbledon Phenomenon") is a chiefly British and Japanese analogy (which possibly originated in Japan) which compares the tennis fame of the Wimbledon Championships, held at the All England Lawn Tennis and Croquet Club in Wimbledon, London, with the economic success of the United Kingdom's financial services industries – especially those clustered in the City of London.
 The point of the analogy is that a national and international institution (the All England Club) can be highly successful despite the lack of strong native competition, as in modern tennis Britain has produced very few Wimbledon champions, with only Ann Haydon Jones, Virginia Wade (both women's singles), Jonathan Marray (men's doubles), Andy Murray (men's singles), John Lloyd, Jeremy Bates, Jo Durie, Jamie Murray and Heather Watson (mixed doubles) winning titles in the Open Era.
