La Rochelle

Originally formed in 1898, Stade Rochelais won three regional Atlantic championships in the early part of the 20th century, qualifying them for the French Championship, where they reached the quarter-finals twice and the semi-finals once. The popularity of rugby league in the area lessened the number of available players, and in 1935 Stade Rochelais merged with neighbours Union Sportive Rochelaise.

Occupation of La Rochelle by troops from Nazi Germany, accompanied by a banning of rugby league by the Vichy Government, forced the city's rugby league club La Rochelle-Etudiants XIII to also be merged into Stade Rochelais in 1941. This was overseen by club President Marcel Deflandre, who was later executed for his role as part of the French Resistance - the club's stadium is named Stade Marcel-Deflandre in his honour.

The club formed a school for training players and coaches in the 1950s, resulting in them reaching the French Championship quarter-finals three times in the 1960s. They were relegated in 1985, returning in 1997. They were again relegated in 2002, though they won the Challenge Yves du Manoir that same year. They retained the Challenge title the following year but were not promoted again until 2010. They spent one season in Top 16 before being relegated again.

Les Maritimes came third in the 2013–14 Rugby Pro D2 season and were promoting after beating Agen in the play-off final.

In May 2022, they won both their first ever trophy and first ever Champions Cup defeating Leinster 24–21 at the Stade Vélodrome.

In May 2023, they retained the Champions Cup again defeating Leinster this time 27–26 at the Aviva Stadium.
