Sporting Clube de Braga B, commonly known as Sporting de Braga B or just Braga B, is a Portuguese football team. It is the reserve team of S.C. Braga. Reserve teams in Portugal play in the same league system as the senior team, rather than in a reserve team league. However, they cannot play in the same division as their senior team, therefore Braga B is ineligible for promotion to the Primeira Liga and also cannot play in the Taca de Portugal and Taca da Liga.
SC Braga had a B team until the 2005–06 season where it played in the Portuguese Second Division. Prior to the end of the 2005–06 season, it was announced that Braga B would fold from the Portuguese league system along with the B teams of Benfica, Porto and Sporting. The club refounded itself in the 2012–13 season, when a new set of rules regarding B teams was introduced in Portuguese football system. For 2012–13 season, another five B Teams, alongside Braga B, where refounded and established themselves in Segunda Liga.
Braga B plays its home games at the Estadio Primeiro de Maio, which holds a capacity of 30,000. It inherited the stadium from the senior team who left there in 2003 following the construction of the Estadio Municipal de Braga.
