KFC Uerdingen 05 is a German football club in the Uerdingen district of the city of Krefeld, North Rhine-Westphalia. The one time Bundesliga side enjoyed its greatest successes in the 1980s but now currently plays in the 5th division, Oberliga Niederrhein.
The club was founded on 17 November 1905 as Fußball-Club Uerdingen 05. On 1 August 1919, following World War I, FC was joined by Sportvereinigung des Realgymnasiums Urdingen. During World War II from 1941–45 the club played as part of the combined wartime side Kriegspielgemeinschaft Uerdingen alongside VfB 1910 Uerdingen (which was known from 1910–19 as Sport-Club Preussen Uerdingen). That partnership continued after the war with the two clubs playing as Spielvereinigung Uerdingen 05. On 20 February 1948, VfB became independent again and in 1950 SpVgg resumed their original identity as FC Uerdingen 05.
