Association Sportive Montferrandaise Clermont Auvergne is a French professional rugby union club from Clermont-Ferrand in Auvergne-Rhône-Alpes that currently competes in Top 14, the top level of the French league system. Clermont are two times French champions in 2009-10 and 2016-17. The rugby section is a part of a multi-sport club called AS Montferrand, which was founded in 1911 and adopted that name in 1919. Although the rugby section changed its name to the current ASM Clermont Auvergne in 2004, it is still frequently referred to as Montferrand both within and outside France.
