The club was established in 2010 as part of the union between the old clubs of Reims Champagne Basket club (RCB) and the ESPE Basket Pro club of Châlons-en-Champagne. Since 2012, the team plays in the LNB Pro A, the top tier division of French basketball.
The historical regional rivals of Reims Champagne Basket club (RCB) and the ESPE Basket Pro club of Châlons-en-Champagne, combined forces to create a strong, financially stable, competitive ball club on the French elite professional stage. The club was founded as Champagne Châlons-Reims Basket (CCRB) on 17 June 2010. 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.
In 2020, the club changed its name to "Champagne Basket".
