Champagne Châlons-Reims Basket also known as CCRB is a professional basketball club based in both the cities of Reims and Châlons-en-Champagne (France) as part of the union between the old Reims Champagne Basket club (RCB) and the ESPE Basket Pro club of Châlons-en-Champagne. The historical regional rivals combined forces to create a strong, financially stable, competitive ball club on the French elite professional stage. Two years following up the union, the Ligue Nationale de Basket (LNB) invited the CCRB to move up directly to the LNB Pro A through a wild-card. Their home arenas are Complexe Sportif René Tys (Reims) and Palais des Sports Pierre de Coubertin (Châlons) that each hosts half their home games.
