The 2020–21 season was the 77th season in the existence of Lille OSC and the club's 21st consecutive season in the top flight of French football. In addition to the domestic league, Lille participated in this season's edition of the Coupe de France and the UEFA Europa League. The season covered the period from 1 July 2020 to 30 June 2021.
On 23 May 2021, with a win over Angers on the final day of the season, Lille were crowned league champions. The achievement was very surprising and was considered an upset, as Paris Saint-Germain had always been the favourites to win Ligue 1 for the fourth time in a row. It was Lille's fourth top-flight title in the professional era and their first since 2010–11, when Eden Hazard was named the competition's player of the year. Lille's points tally of 83 was the best in their history and they only lost three matches all season.
