Carcassonne

As early as 1899 rugby was introduced to the rich and well off in Carcassonne. The club reached the rugby championship final in 1925, then in 1930 along with 11 other clubs they broke away from the French rugby union and began their own competition. With the creation of the French rugby league championship in 1934 several rugby league clubs began springing up throughout the France. It was not until May 1938 though that AS Carcassonne would join. Their debut season saw them finish 3rd before losing in the semi-finals to US Villeneuve. The following season they reached the cup semi-final, but before it could be played war broke out and the season was ended.

The French Vichy government placed a ban on rugby league as of 19 December 1941.

After the war AS Carcassonne returned to rugby league under the direction of Paul Barriere. Several new players joined the club, most notably nineteen-year-old Puig Aubert; this influx of players would signal both new ambition and success for the club who would go on to win five Championship titles over the next ten years coupled with four Lord Derby Cups.

With the completion of the golden years in early 1950s the club went through a somewhat lean period where silverware would evade them for several years until the early 1960s when the club would have a semi-return to their glory days winning back to back Lord Derby Cups and another four French Championships between 1966 and 1976.

Since the completion of the 1977 season the club's fortunes took something of a slide by their standards. The club managed only a single French Championship in 1992 and two Lord Derby Cups in 1983 and 1990. In seasons 1992–93 and 1993–94 they competed in the British cup competition the Regal Trophy losing in the opening round on both occasions firstly to Wigan 0-52, and then Carlisle 24-36 the following season.

The new millennium didn't bring too much silverware either but having been runner up in the cup in 2004 and 2007 they lifted the trophy again in 2009. 2012 was a memorable campaign that ended with them completing a league and cup double beating Pia XIII in both finals. The reward for winning the title was a place in the British rugby league Challenge Cup in 2013, they lost 16–24 away at Workington Town. Runners up in 2014 v Toulouse Olympique in the cup and a year later they were runners up again this time in the league against the same opponents. Season 2016-17 saw them win the Lord Derby Cup for a record 14th time after beating Lezignan Sangliers 30–24. In 2023 Carcassonne added a sixteenth Lord Derby Cup by beating Albi in Perpignan.

In December 2023, the club submitted an application to join the British rugby league system starting in League 1 from 2026.
