The 2009–10 season was Olympiacos's 51st consecutive season in the Super League Greece and their 84th year in existence. Olympiacos finished 2nd in the regular season of the Greek Super League and ranked last at the play-off games, resulting in a 5th place at the League, the worst position of team's recent seasons. Olympiacos also participated in UEFA Champions League 2009–10, and managed to qualify to the knock-stage (round of 16). They lost twice from French side Bordeaux, 3–1 on aggregate.
This season was the last season with Sokratis Kokkalis as chairman of the club. The 5th league position as well as the team's low level of spectacle created a disappointing atmosphere, resulting in Kokkalis's decision to leave the club after two decades of constant presence.
