The 2011 World Touring Car Championship season was the eighth season of the FIA World Touring Car Championship, and the seventh since its 2005 return. The championship, which was open to Super 2000 cars and Diesel 2000 cars, began with the Race of Brazil at Curitiba on 20 March and ended with the Guia Race of Macau at the Guia Circuit on 20 November, after twelve events and twenty-four races.

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.
