Fußballclub Red Bull Salzburg, commonly known as simply Red Bull Salzburg, is an Austrian professional football club based in Wals-Siezenheim, that competes in the Austrian Bundesliga, the top flight of Austrian Football. Their home ground is the Red Bull Arena. Due to sponsorship restrictions, the club is known as FC Salzburg and wears a modified crest when playing in FIFA and UEFA competitions.

The club was originally known as SV Austria Salzburg and played under various sponsored names, including SV Casino Salzburg and SV Wüstenrot Salzburg. In 2005, it was acquired by Red Bull GmbH, which rebranded the club and changed its traditional violet and white colours to red and white. This transformation led some supporters to establish a new club, SV Austria Salzburg, in response.

Founded in 1933, the club won its first Bundesliga title in 1994, which was the first of three in the span of four seasons which also saw them reach the 1994 UEFA Cup final. The club has won seventeen league titles and nine Austrian Cups, all nine of which came as doubles, as well as three Austrian Supercups. Salzburg has dominated Austrian football over the recent past, winning 14 league titles in 17 seasons including 10 in a row from 2014 to 2023.
