Idrottsföreningen Kamraterna Göteborg (officially IFK Göteborg Fotboll), commonly known as IFK Göteborg, IFK (especially locally) or simply Göteborg, is a Swedish professional football club based in Gothenburg. Founded in 1904, it is the only club in the Nordic countries that has won one of the main UEFA competitions, having won the UEFA Cup in both 1982 and 1987. IFK is affiliated with Göteborgs Fotbollförbund and play their home games at Gamla Ullevi. The club colours are blue and white, colours shared both with the sports society which the club originated from, Idrottsföreningen Kamraterna, and with the coat of arms of the city of Gothenburg. The team colours have influenced the historical nickname Blåvitt. The blue and white are in stripes, with blue shorts and socks.

Besides the two UEFA Cup titles, IFK have won 18 Swedish championship titles, second most in Swedish football after Malmö FF, and have the second most national cup titles with eight. The team has qualified for four group stages of the UEFA Champions League, and reached the semi-finals of the 1985–86 European Cup. IFK Göteborg is the only club team in any sport to have won the Jerring Award, an award for best Swedish sports performance of the year voted by the Swedish people, for the 1982 UEFA Cup victory. IFK is the most popular football club in Sweden, with diverse country-wide support.

IFK Göteborg play in the highest Swedish league, Allsvenskan, where they have played for the majority of their history. They have played in the Swedish first tier continuously since 1977, which is the longest ongoing top-flight tenure in Sweden. The club won its first Swedish championship in 1908, four years after the founding, and has won at least one championship title in every decade since, except the 1920s, 1970s and 2010s. IFK Göteborg's most successful period was from 1982 to 1996, when the team prospered in European football and won 10 out of 15 Swedish championships.
