The 1926 KBUs Pokalturnering (Unofficial English translation: 1926 KBU Cup, 1926 Copenhagen Cup) was the 17th edition of the regional tournament, KBUs Pokalturnering, the highest senior cup competition organised by the Copenhagen FA (KBU). The tournament was held in the fall of 1926 with BK Frem, then based on Enghavevej, as the defending cup champions. The season was launched with one match on 22 August 1926 between the last season's runners-up in Copenhagen Football League B.93 and the newly promoted league club BK Fremad Amager. This season's installment was won by B.93 after defeating Kjøbenhavns BK 5–1 in the final played at Københavns Idrætspark on 7 November 1926, which was the club's fifth cup title after having contested in eight finals of the tournament. The 8 participants in the tournament included the six members of the 1925–26 KBUs Mesterskabsrække and the two highest placed teams from the 1925–26 KBUs A-række.
The runners-up of the 1925–26 KBUs A-række, the second-tier league under the Kjøbenhavns Boldspil-Union, managed to reach the second round by defeating Akademisk BK from the regional top-tier Copenhagen Football League, before eventually being eliminated by Østerbro-based B.93. In the very first round, the two KBUs Mesterskabsrække clubs of B 1903 and BK Frem had to play two additional matches over the course of 5 weeks time before a winner could be found, that would go through to the semi-finals. KFUMs BK and Kjøbenhavns BK played one extra quarterfinal game to determine which club would participate in the semi-finals. The extra matches would generate an additional income of DKK 5–6,000 to both clubs. Forward Poul "Tist" Nielsen of Kjøbenhavns BK became the tournament's top goal scorer with 8 goals, which he scored during the course of the club's four cup matches.

Match summary
Københavns Idrætspark acted as the host stadium on 7 November 1926 for the fourteenth time in the history of KBUs Pokalturnering. The weather at the game was sunny and relatively less windy, but with a wet and greasy surface due to the great rain shower in the morning and the previous night. This required high studs under the players' football boots for stability, which not all players had. Kjøbenhavns Boldklub's football kit consisted of blue-white shirts during the match, while the B.93 players had all white shirts. The final match was a repetition of the 1910 and 1916 cup finals, who had previously meet against each other a total of six times in the competition's history. Based on the team's recent league results, B.93 were regarded as favorites to win the cup title by various newspapers. The previous weekend, on 31 October 1926, the two teams had also met each other in the league resulting in a 3–1 win to B.93.
The match was refereed by Lauritz Andersen (affiliated with BK Velo) together with two of KBU's most used referees at that time, Valdemar Nilsson and Poul Jørgensen, as the linesmen featured in yellow shirts. The draw at the beginning of the match concerning the right to choose the starting half of the football field was won by Kjøbenhavns BK's captain Poul "Tist" Nielsen, who choose the goal facing the western side of the stadium, towards Øster Allé, which meant the KB players would start the game with the sun and wind in their backs. B.93 fielded the exact same team line-up, that they had used in their previous match the previous Sunday, while Kjøbenhavns BK fielded three relatively new players in the squad, namely the newly promoted youth players Harald Lindemann, Holger "Dirk" Asmussen and Poul Hansen (as replacement for forward Erik Eriksen) — the last one having played youth matches the previous season and reserve team matches in the fall of 1926. Poul Hansen, placed as left innerwing, would get his debut on KB's first team in this match. Poul "Tist" Nielsen, the captain of Kjøbenhavns BK, was the only player on the field having also participated in the 1910 final, while Anthon Olsen of B.93 was the oldest player on the field being 37 years old.
