Stade Montois is a multi-sports club (28 sections) but its rugby team has always been its flagship. After winning a few regional titles between the two world wars, it reached the top of French club rugby four times in 15 years. It lost its first three French championship finals to Castres Olympique in 1949 (3-14, in a replay, after the original final had ended in a 3-3 draw), to FC Lourdes in 1953 (16-21), and to Racing Club de France in 1959 (3-8). Their finest hour came in 1963 in an all Landes-final against US Dax, won by the Yellow and Black 9-6. They had finally won one, whereas their Dax neighbours would lose all five finals they would play in.
It finished in the bottom table in the first-tier Top 14 in the 2008–09 season. They had just been promoted to the Top 14 after winning the Pro D2 promotion playoffs. They remained in Pro D2 for three seasons before successfully navigating the 2012 promotion playoffs.
