Racing Club Chalonnais, also known simply as RC Chalon is a French rugby union club from Chalon-sur-Saône. They competed in Fédérale 1, the third level of the French league system, in the 2009–10 season, but recent financial troubles saw them relegated two levels, to Fédérale 3, for 2010–11. They have since returned to Fédérale 1.
