Amateur era The club was established in 1911 as AS
Michelin, though they changed their name to AS Montferrandaise in 1922 due to legal obligation. The club was started by Marcel Michelin, the son of
André Michelin, the founder of the Michelin tyre manufacturer. He died in deportation at Buchenwald; he had been deported there as a member of the Resistance and was involved in two successful escape attempts before dying during the third. The club made its first final of any competition in 1935, where they played
Perpignan for the
Challenge Yves du Manoir. AS Montferrand lost the match, 3–3 and 9–0. The following year they featured in their first championship final; though they lost to
RC Narbonne 6 points to 3. They made the final again in 1937, though that match was also lost, 13 points to 7 to
CS Vienne. The following season the club won its first title; winning the Challenge Yves du Manoir by defeating Perpignan 23 points to 10. During the 1940s the club contested the
Coupe de France on two occasions, in 1945 and 1947. The club lost on both occasions, by one point, 14 to 13 to
SU Agen in 1945, and then 14 to 11 against
Toulouse in 1947. 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 became a force during the 1970s, starting in 1970 with a 3 points to nil championship loss to
La Voulte Sportif. 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. The club then contested the championship final in 1978, though they lost to Béziers. They also lost the Challenge Yves du Manoir in 1979, against Narbonne. In 1994 season the club contested both the French championship and the Challenge Yves du Manoir. They lost the Challenge Yves du Manoir to Perpignan (the third time the clubs had met in the competition final). They also lost the championship, defeated 22 points to 16 by Toulouse.
Professional era The club contested two finals in the 1999 season as well, the French championship and the
European Challenge Cup. They won the European Challenge Cup, defeating fellow French club
CS Bourgoin-Jallieu 35 points to 16 at the Stade Gerland in Lyon. However they lost the domestic final, being defeated by Toulouse again, 15 points to 11. The club would meet Toulouse again in the season final of 2001, with Toulouse winning 34 points to 22. In 2004 they contested the European Challenge Cup again, though they lost to English club
Harlequins, by one point, 27 to 26 at the last minute. The team experienced a hard period between 2002 and 2006 and it was only with the arrival of Vern Cotter, in the middle of 2006, that the team's form began to improve. 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. Montferrand developed further under Vern Cotter during the following two seasons, but they lose two more finals against Toulouse in 2008, and Perpignan in 2009. But the team continues to bounce back and perform well years of years. In 2010, in the Heineken Cup the team was drawn against Leicester Tigers and Ospreys in a tough pool. Despite this Montferrand succeeded in winning the pool and were subsequently drawn against the holders of the cup, Leinster Rugby. That was the beginning of what would become one of the greatest rivalries in rugby. In an epic battle, Montferrand lost 29–28. After this loss, they went on to win all of their remaining games to win the French championship against Perpignan (19–6) with a notably exceptional display during the semi-final against RC Toulon in Saint-Étienne. In 2012 they reached the semi-final of the
Heineken Cup. They were beaten by
Leinster Rugby and were inches from winning the game at the end but
Wesley Fofana dropped the ball on Leinster's try line. Clermont reached the
Heineken Cup final for the first time in 2013 after they beat
Munster Rugby 16–10 in the semi-final in Montpellier. They subsequently lost to Toulon in the HEC final which was held in Lansdowne Road in Dublin on 18 May 2013 by a single point (16–15). In 2014, Clermont reached the
Heineken Cup semi-final of the play-offs for the second consecutive time and lost to
Saracens. 2015 saw Clermont make it to the final of the European Cup (now
European Rugby Champions Cup) but lost to
RC Toulon 24–18. A few weeks later, they also lost the final of the French
Top 14 against
Stade Français 12–6. 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. But they finally reached the French championship semi-final with a highly controversial lose against Racing 92. 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. They lost the European Cup against reigning champions Saracens. In January 2020, Clermont acquired a minority stake in the American rugby club
New Orleans Gold. In addition to player exchanges, the teams will seek to facilitate cultural exchanges between the state of
Louisiana and France. == Honours ==
