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.[3]
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.[4]
