The 2013 World Touring Car Championship season was the tenth season of the FIA World Touring Car Championship, and the ninth since the series was revived in 2005. The championship, which was reserved for cars run to Super 2000 regulations, began with the Race of Italy on 23 March and concluded with the Race of Macau in support of the Macau Grand Prix at the Guia Circuit on 17 November, after twenty-four races at twelve events.

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.
