The 2010–11 season is French football club Olympique Lyonnais's 52nd season in Ligue 1 and their 22nd consecutive season in the top division of French football. The season is the club's second straight season overall where it has not won any silverware. Due to the club's second-place finish the previous season, Lyon will compete in the UEFA Champions League for the 11th-straight season.

On 8 June 2010, Lyon reached a three-year agreement on a partnership with Groupama, an international insurance company based in Paris. The deal is valued at €4.5 million a year. The company's logo will be displayed on the back of the player's shirts.

On 9 June, French newspaper L'Equipe reported that Olympique Lyonnais sporting director Marino Faccioli would depart the club on 1 July to become the director of the France national football team. The report also stated that Faccioli was new manager Laurent Blanc's first-choice for the position. Two hours later, Faccioli denied the report stating that no agreements had been made between the two parties. On the previous day, Lyon confirmed the arrival of Philippe Sauze as a new general director. Sauze is the current vice-president of American company Electronic Arts. The hiring of Sauze will redefined the different functions of several directors with the "possible departure of Marino Faccioli to the France team" being in mind.

On 14 June, Lyon confirmed their first transfer arrival to the club after reaching an agreement with Rennes for the transfer of Jimmy Briand. The transfer fee was priced at €6 million and Briand is expected to replace Sidney Govou who departed the club for Greek side Panathinaikos on 5 July.
