Le Club Omnisports des Ulis is a French association football club founded in 1977. They are based in Les Ulis, Essonne and are currently playing in the Division Supérieure Régionale of Île-de-France, the seventh tier of the French football league system. They play at the Stade Salinier, named after Jean-Marc Salinier, a local politician from the area, in Les Ulis. CO Les Ulis is primarily known for being the club where France national team members Patrice Evra and all time leading goalscorer Thierry Henry began their careers. Henry, after achieving major success at English club Arsenal, now plays for Major League Soccer club New York Red Bulls. The club has also developed emerging youth prospects, such as Yaya Sanogo and Sega Keita.
CO Les Ulis was formed relatively late, primarily due to the commune of Les Ulis also coming into existence late. Both the city and the club formed in 1977 with the commune coming into existence in February and the club being formed in May. After only 8 years of existence, the club had already developed eight sections of sport, which had over 1,000 members associated with football being the most popular in the club. By 2005, these numbers rose to over 36 sections of sport with 3,600 members.
CO Les Ulis honours are minimal with the club slowly ascending the French football league system since achieving promotion from the Division d'Excellence during the 1994–95 season. The club is currently playing in the Division Honneur of the Île-de-France region after achieving promotion from the Division Supérieure Régionale during the 2009–10 season.
