As of the 2024–25 season, the club plays in the Championnat National 2, the fourth tier in the French football league system.

Stade Briochin has played for the majority of its existence at the amateur levels of the French football league system, but did spend three seasons in the second tier of the professional league during the period 1993–1997, before suffering liquidation and an enforced relegation to the fifth tier.

Until 1959, Stade Briochin competed in the Ligue de Bretagne, the regional amateur league of Brittany.

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.

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.
