The 2015 World Touring Car Championship was a motor racing competition organised by the FIA for Super 2000 cars. It was the twelfth FIA World Touring Car Championship, and the eleventh since the series was revived in 2005. The championship comprised a Drivers Championship and a Manufacturers Championship, which were won by José María López and Citroën respectively.

The FIA World Touring Car Championship was an international touring car championship promoted by Eurosport Events and sanctioned by the Fédération Internationale de l'Automobile (FIA). It has had several different incarnations, including a single season in 1987 as the World Touring Car Championship and most recently a world championship (WTCC) that has run between 2005 and 2017. Following the 2017 season, an agreement was reached for the FIA WTCC to become FIA WTCR and use the TCR technical regulations.
