Union sportive Oyonnax Rugby is a French rugby union club from Oyonnax [ɔ.jɔ.na] in the Ain département of the région Auvergne-Rhône-Alpes, currently playing in Rugby Pro D2, the second division of the country's professional rugby system. They play at Stade Charles-Mathon (capacity 11,400). They wear black and red.
They were founded in 1909 as Club Sportif Oyonnaxien and were renamed Union Sportive Oyonaxienne in 1940, as sports clubs were forced to unite by the Vichy régime. Oyonnax played in the regional leagues until 1967 when they joined the First Division (64 clubs). They were relegated to the lower divisions a few years later and bounced back to Group B of the First Division (the Second Division in fact) in 1988. Finally, in 2003 they reached the Fédérale 1 final and although they went down to Limoges (18-20), they moved on to the professional Pro D2. In the 2012/13 season, they won Pro D2 and were promoted to the top-flight Top 14. They were repromoted after 2016/17, having been relegated the previous season.
