The 2008–09 Coupe de la Ligue began on 19 August 2008, and its final was held on 25 April 2009 at the Stade de France. The former defending champions, Paris Saint-Germain, were initially barred from participating in the cup after a group of PSG supporters unfurled an offensive banner during last year's final. After PSG appealed the ban, however, the Tribunal Administratif de Paris judge vacated the ruling allowing PSG to defend their Coupe de la Ligue title. Due to this, a new draw was announced.French Football Federation (FFF) president Jean-Pierre Escalettes vowed to get the second ruling overturned, stating, "I won't give up," and, "I can't allow acts like this to go unpunished," but was unsuccessful. The winners of the Coupe de la Ligue qualified for the third qualifying round of the 2009–10 UEFA Europa League.
Ligue 1 club Bordeaux won the competition by defeating Ligue 2 club Vannes by a score of 4–0 in the final.
