The rugby section is a part of a multi-sport club called AS Montferrand (also known as ASM Omnisports), which was founded in 1911 and adopted that name in 1919.

The city is where Marcel Michelin, the son of the founder of the French tyre manufacturer, decided to implement the first factory but also the stadium after the creation of ASM for its workers before World War I. L'ASM, as they are also called, have reached the French Championship final thirteen times, losing on each occasion until their eleventh trip in 2010, when they won the championship in their 100th year as a club.

The following season the club won its first title; winning the Challenge Yves du Manoir by defeating Perpignan 23 points to 10.

It would be another 10 years until the club featured in another competition final; losing to US Dax in the 1957 Challenge Yves du Manoir.

The club then contested the Challenge Yves du Manoir twice in a row over the 1972–73 seasons; losing both finals, against AS Béziers and Narbonne respectively.

Then they won the competition in 1976, defeating SC Graulhet 40 points to 12 just a few days after the death of the young international winger, Jean-François Philiponeau, struck on the field during an exhibition game.

They lost the Challenge Yves du Manoir to Perpignan (the third time the clubs had met in the competition final).

They won the European Challenge Cup, defeating fellow French club CS Bourgoin-Jallieu 35 points to 16 at the Stade Gerland in Lyon.

[citation needed] In Vern Cotter's first year as head coach, Clermont reached their first final since 2001 (which they lost in the last minute against Stade Français), and won the European Challenge Cup against Bath at the Twickenham Stoop.

2016 saw Clermont having their first blow in the European Rugby Champions Cup since 2011 by failing to make the quarter final after a late loss against Bordeaux at home.

However, the team bounced back and produced during the season 2016–2017, reaching again two finals in the French Top 14 and European Champions Cup.
