The 2020 FIA World Rally Championship was the forty-eighth season of the World Rally Championship, a rallying competition organised by the Fédération Internationale de l'Automobile (FIA). Teams and crews competed in seven rallies for the World Rally Championships for Drivers, Co-drivers and Manufacturers. Crews were free to compete in cars complying with Rally1 and Rally2 regulations; however, only manufacturers competing with World Rally Cars homologated under regulations introduced in 2017 were eligible to score points in the Manufacturers' championship. The championship began in January 2020 with the Rallye Monte-Carlo and concluded in December 2020 with Rally Monza. The series was supported by the World Rally Championship-2, World Rally Championship-3 and Junior World Rally Championship categories at selected events.

The World Rally Championship is an international rallying series owned and governed by the FIA. Inaugurated in 1973, it is the second oldest of the FIA's world championships after Formula One. Each season lasts one calendar year, and separate championship titles are awarded to drivers, co-drivers and manufacturers. There are also two support championships, WRC2 and WRC3, which are contested on the same events and stages as the WRC, but with progressively lower maximum performance and running costs of the cars permitted. Junior WRC is also contested on five events of the World Rally Championship calendar.
