XIII Catalan were a French rugby league team from Perpignan, in the Catalan Pyrénées-Orientales region of France. They were founded in 1935, and thus were founding members of the French rugby league championship. In 2000 they merged with nearby neighbours AS Saint Estève to form Union Treiziste Catalane, now better known in the English-speaking world by their European Super League identity of Catalans Dragons.
The references in the titles to the number thirteen (XIII and Treiziste) relate to the naming of the sport of rugby league in France as Rugby à treize (Rugby of 13, from the number of players in a team).
Notable players include Puig Aubert.
