KBUs Pokalturnering (unofficial English translation: KBU Cup, Copenhagen Cup) was a Danish regional knockout association football competition contested annually from 1910 to 1953 by clubs that were members of the regional football association Copenhagen FA (KBU).
[1][2] Organised by and named after KBU, the competition rules has varied from being open to all Copenhagen clubs (1910–1919 and 1947–1953) and being a closed tournament (1920–1946) reserved only for the highest ranking clubs, and as a consequence the number of participants have varied greatly throughout its history.
[3] When both the Sommerpokalturneringen (who for several seasons had functioned as a qualifying tournament) and the KBUs B-Pokalturnering, both featuring the lower ranking KBU teams, were discontinued after their 1946 edition, the Copenhagen FA again allowed lower ranking clubs to participate in the association's primary cup competition, increasing the number of teams to 52.
[1] The most successful club in the history of the tournament were Østerbro-based B.93, who won a total of 13 cup titles and appeared as a losing finalist on 11 occasions.
[11] The clubs participated with reserve teams in the 1914 edition due to many of the first squad players being summoned by the Danish mobilization at the outbreak of World War I, so it was decided that the cup trophy would not be in play, and hence Kjøbenhavns Boldklub did not gain a lot this year by winning the final match for the fifth time in the tournament's history.
