AJ Auxerre is the rare top-flight club that was founded by a priest. On 29 December 1905 the abbot Ernest Deschamps established the Association de la Jeunesse Auxerroise, a youth association that began by playing in a Catholic league. His name is still carried by the club's ground, the Stade de l'Abbé-Deschamps, which stands on the banks of the Yonne. For the next seven decades the club made a slow climb from local amateur football, and few outside Burgundy would have predicted where it would end up.
The man who turned that climb into a revolution was Guy Roux, who coached the team for more than four decades between 1961 and 2005. Under him Auxerre reached the French first division for the 1980–81 season and then stayed there for 32 consecutive seasons, until relegation in 2012. Roux built the side on youth development, stability and tightly controlled budgets, and for a long time the club was held up as the model of a small provincial team competing with the biggest names in the country.
The club's first major trophy was the Coupe de France in 1994, won 3–0 against Montpellier. Two years later came the greatest season in its history: in 1995–96 Auxerre won its only French championship, finishing with 72 points, four more than third-placed Monaco, and added the Coupe de France to complete the double. Further cup wins followed in 2003 and 2005, which brought its total to four. The striker Stéphane Guivarc'h was part of the double-winning squad, though he played a secondary role that season with three league goals in 23 appearances, and he later scored for the club in Europe.
Auxerre's European story began in 1984–85, when it entered the UEFA Cup for the first time and was drawn against Sporting in the first round. Its best run came in 1997–98. After winning the Intertoto Cup in 1997, it reached the quarter-finals of the UEFA Cup, and Guivarc'h scored seven goals to finish as the competition's top scorer. The club also qualified for the Champions League after the 1996 title and again after finishing third in 2001–02, a season in which Djibril Cissé scored 22 league goals. A second-place finish behind Marseille in 2009–10 earned another place in the competition.
The white-and-blue club went through lean years after the 2012 relegation, but it has since returned to Ligue 1. In 2025–26 it finished 15th of 18 teams, a reminder that the club still lives close to the limit. Its identity remains the one shaped by Deschamps and Roux, in which a modest town, patient work and a conviction in young players have mattered more than money.
