Stade Brestois 29, commonly known as Stade Brestois or simply Brest, is a French professional football club based in Brest. It was founded in 1950 following the merger of five local patronages, including Armoricaine de Brest, founded in 1903. The club has competed in Ligue 1, the top division of French football, ever since being promoted to the top flight during the 2018–19 season.

In its early years, Brest made a rapid rise in the hierarchy of regional football, to the point of being promoted to the Championnat de France Amateur in 1958. The club joined the Division 2 in 1970, then finally reached the Division 1 in 1979. It experienced its sporting peak between 1981 and 1991 under the presidency of François Yvinec, playing nine seasons in the highest tier in ten years. In 1991, the club was demoted before filing for bankruptcy a few months later. The club only returned to the second division in 2004 and Ligue 1 in 2010. At the end of the 2012–13 season, it had respectively thirteen and seventeen seasons in the first two divisions. In 2023–24, underdogs Brest achieved an unlikely third-place finish in Ligue 1 and thus qualified for the 2024–25 UEFA Champions League, marking the first appearance in any European competition in the club's history.

Stade Brestois has been chaired since 10 May 2016 by entrepreneur Denis Le Saint.
