Lyon

Olympique Lyonnais was initially formed under the multisports club Lyon Olympique Universitaire, which was originally formed in 1896 as Racing Club de Lyon. Following numerous internal disagreements regarding the cohabitation of amateurs and professionals within the club, then-manager of the club Félix Louot and his entourage contemplated forming their own club. On 3 August 1950, Louot's plan came to fruition when Olympique Lyonnais was officially founded by Dr. Albert Trillat and numerous others. The club's first manager was Oscar Heisserer and, on 26 August 1950, played its first official match defeating CA Paris-Charenton 3–0 in front of 3,000 supporters. In just the club's second year of existence, Lyon was crowned champion of the second division, securing promotion to the first division. The club maintained its first division place for the remainder of the decade, excluding a year's stint in the second division for the 1953–54 season.

Lyon achieved moderate success during the 1960s and 1970s with the likes of Fleury Di Nallo, Néstor Combin, Serge Chiesa, Bernard Lacombe and Jean Djorkaeff playing major roles. Under manager Lucien Jasseron, Lyon won its first-ever Coupe de France title defeating Bordeaux 2–0 in the 1963–64 season. The club also performed respectably in the league under Jasseron's reign until the 1965–66 season, when Lyon finished 16th, which ultimately led to Jasseron's departure. His replacement was Louis Hon, who helped Lyon win their second Coupe de France title after defeating Sochaux 3–1 in the 1966–67 season. Lyon was managed by former Lyon legend Aimé Mignot heading into the 1970s. Under Mignot's helm, Lyon won its third Coupe de France title in 1972–73, beating Nantes 2–1.

In June 1987, Lyon was bought by Rhône businessman Jean-Michel Aulas who took control of the club aiming to turn Lyon into an established Ligue 1 side. His ambitious plan, titled OL – Europe, was designed to develop the club at the European level and back into the first division within a period of no more than four years. The first manager under the new hierarchy was Raymond Domenech. The aspiring chairman gave Domenech carte blanche to recruit whoever he saw fit to help the team reach the first division. They went on to accomplish this in Domenech's first season in charge. Lyon achieved its zenith under Domenech when it qualified for the UEFA Cup. For the remainder of his tenure, however, the club underachieved. Domenech was replaced by former French international Jean Tigana, who led the team to an impressive second place in the 1994–95 season.

At the start of the new millennium, Lyon began to achieve greater success in French football. The club established itself as the premiere club in France defeating Marseille and Paris Saint-Germain and also became France's richest club. Lyon became known for developing promising talent who went on to achieve greatness not only in France, but also abroad and internationally. Notable examples include Michael Essien, Florent Malouda, Sidney Govou, Juninho, Cris, Eric Abidal, Mahamadou Diarra, Patrick Müller and Karim Benzema. Lyon won its first ever Ligue 1 championship in 2002, starting a national record-breaking streak of seven successive titles. During that run the club also won one Coupe de France title, its first Coupe de la Ligue title and a record six Trophée des Champions. The club also performed well in UEFA competitions, reaching as far as the quarter-finals on three occasions and the semi-finals in 2010 in the UEFA Champions League. Lyon's streak and consistent dominance of French football came to an end during the 2008–09 season, when it lost the title to Bordeaux.

OL has begun investment in sports outside of football. OL operates an esports team in China, and in 2019 purchased a minority stake in the local ASVEL basketball club, specifically purchasing a 25% interest in ASVEL's men's side and a 10% interest in the women's side.

More recently, OL announced in December 2019 that it would buy an 89.5% stake in the U.S. National Women's Soccer League team known at the time as Reign FC. The purchase closed in January 2020 following approval of the NWSL board. Several weeks later, OL announced the rebranding of Reign FC as OL Reign.

In the 2019–20 season, Lyon suffered a poor start to the season, and ended the season in seventh place, as the league was cancelled due to the coronavirus outbreak. Lyon also reached the final of the Coupe de la Ligue, however, they eventually lost to Paris Saint-Germain 6–5 on penalties. Ultimately, this meant that Lyon failed to qualify for European competition for the first time in 24 years. In the Champions League, Lyon were more successful, defeating Juventus in the round of 16 and Manchester City in the quarter-final to reach the semi-finals for the first time in 10 years. However, they eventually lost 3–0 in the semi-final to Bayern Munich, eliminating Lyon from the competition.
