Olympique de Marseille is a French professional football club based in Marseille. Founded in 1899, they play in Ligue 1 and have spent most of their history in the top tier of French football. Marseille have been French champions eight times, and have won the Coupe de France ten times (a record) and became the first and only French club to win the UEFA Champions League in 1993.

Olympique de Marseille's home is the 60,031-person-capacity Stade Vélodrome football stadium in the south of the city, where they have played since 1937. In 1997, they were bought by Franco-Swiss billionaire Robert Louis-Dreyfus.

Marseille's traditional kit colours are white shirts and shorts with white socks. The current badge was adopted in 2004. The club's motto Droit Au But (French for "Straight to the Goal") appears under the badge and a star representing the victory in the Champions League is featured on the top. The club enjoys a large fan base, with the highest average all-time attendance in French football. Their average home gate for the 2008–09 season was 52,276, the highest in the Ligue 1.
