Until 1959, Stade Briochin competed in the
Ligue de Bretagne, the regional amateur league of
Brittany. For five of the next ten years they contested the Championnat de France Amateur, which at the time was the top tier of Amateur football. They competed around this level, as the French football league system restructured itself, until 1988 when they were relegated from the
Ligue de Bretagne Division Honneur (the fifth tier, in effect, at this stage) to the
Ligue de Bretagne Division Supérieure Régionale. From the 1988–89 season, the club won promotions in three out of four seasons, and in 1993–94 they finished 6th in
Division 2, which is still their highest finish to date. In the
1996–97 season, the club started to suffer from debt issues, and on 24 March 1997 they were liquidated by order of court and administratively relegated from the professional football league. The club restarted in
Championnat de France Amateur 2 for the 1997–98 season, falling to the
Ligue de Bretagne Division Honneur (now the sixth tier) in 2008 and further to the
Ligue de Bretagne Division Supérieure Élite (seventh tier) in 2011. Successive promotions in 2012 and 2013 brought the club back to
CFA 2. In the 2019–2020 season they won promotion to the Championnat National by being top of the
Championnat National 2 Group B table when the season was curtailed due to the
COVID-19 pandemic. In the
2024–25 Coupe de France, Stade Briochin eliminated three professional clubs in a row, starting with
Le Havre in the round of 64 (1–0),
Annecy in the round of 32 (1–1, 4–3 on penalties), and
Nice in the round of 16 (2–1). Their run ended in a home tie against
Paris Saint-Germain in the quarter-finals, losing 7-0. ==Current squad==
