Aalborg Boldspilklub is a Danish sports club based in the city of Aalborg. The club is also known as AaB for short (cf. logo) or Aalborg BK. Through time the club has had branches in cricket, tennis, ice hockey, handball, and basketball, but currently controls teams in football, American football, and floorball. All teams are competing in the top-flight Danish league in their respective sport. The kit sponsor for the club is Adidas, and the principal sponsor for the football team is the regional bank Spar Nord.

AaB was founded on 13 May 1885 by English engineers who were building Jutland's railway system, and the first years was concentrated on the game of cricket. It was initially named Aalborg Cricketklub (Aalborg Cricket club) but the name of the club was changed to Aalborg Boldklub (Aalborg ballclub) in 1899. Football was adopted on an amateur basis in 1902, and has since been the main sport, as the name was changed to the current Aalborg Boldspilklub af 1885 (Aalborg ballgameclub of 1885) in 1906.
