AaB Fodbold

AaB, (full name: Aalborg Boldspilklub, pronounced [ˈʌlˌpɒˀ ˈpʌlˀtspe̝lˌkʰlup]) internationally referred to commonly as Aalborg BK, and occasionally referred to as AaB Aalborg, is a professional football club based in Aalborg, Denmark. The club currently competes in the Danish 1st Division, the second tier of Danish football. AaB is one of the oldest and most historically significant clubs in Danish football, having been founded on 13 May 1885. Initially formed as a cricket club by English railway engineers, the club adopted football in 1902 and has competed under the name Aalborg Boldspilklub af 1885 since 1906.

AaB has traditionally been a mainstay in the Danish top flight, and has won the Danish Superliga four times, in 1994–95, 1998–99, 2007–08, and 2013–14. The latter season remains the club's most successful, as AaB won the domestic double by securing both the league title and the Danish Cup. In total, the club has lifted the national cup three times. After a period of decline in the early 2020s, AaB was relegated from the top tier at the end of the 2022–23 season for the first time in 36 years. The club secured immediate promotion in 2023–24 but was relegated again the following season, returning to the Danish 1st Division for the 2025–26 campaign.

On the European stage, AaB holds the distinction of being the first Danish club to reach the group stage of the UEFA Champions League, doing so in 1995–96 after replacing Dynamo Kyiv, who were expelled for disciplinary reasons. The club later qualified directly for the group stage in 2008–09, and remains one of Denmark's most frequent participants in the competition, second only to F.C. Copenhagen in appearances.
