IFK Göteborg is a Swedish professional football club based in Gothenburg. Founded in 1904, the club has won 18 national championship titles, five national cup titles, and two UEFA Cups.

IFK is arguably the most successful club in Sweden together with Malmö FF, and one of the most successful clubs in all of northern Europe, as it is the only Scandinavian team to have won a pan-European competition. IFK won the UEFA Cup in 1982 and 1987. They currently rank in the highest Swedish league, Allsvenskan, where they have played for the majority of their history. They have played top flight football in Sweden since 1977, which currently is the longest top flight tenure of any club in Sweden—the second longest is Helsingborgs IF, since 1993.

IFK is one of the most popular football clubs in Sweden, with diverse country-wide support. Since the start of the 2009 season, they play all their home games at the newly built Gamla Ullevi stadium.

IFK Göteborg was founded at Café Olivedal on 4 October 1904, becoming the 39th IFK association. A committee for football was created at the historic first meeting; the association's first football match ended in a 4–1 victory against a club from the local area, IK Viking. The foundation of IFK Göteborg was important for the development of football in the city, as until that point, Örgryte IS, the largest of Gothenburg clubs, were dominant. IFK Göteborg represented some needed competition.
