2013 World Touring Car Championship

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.

Yvan Muller secured the Drivers' Championship title in Japan, with two events remaining in the season. Honda won the Manufacturers' Championship. Chevrolet was the defending manufacturers' champion, but it did not support a team in 2013, and thus was unable to defend its title.

James Nash won the Yokohama Drivers' Trophy for independent entries and RML won the Yokohama Teams' Trophy. The Lukoil Racing Team was the defending Yokohama Teams' Trophy winner, but was unable to defend its title as Lukoil closed their own team to support manufacturer Lada Sport team in 2013.
