2021 Junior WRC Championship

The 2021 FIA Junior WRC Championship was the ninth season of Junior WRC, a rallying championship governed by the Fédération Internationale de l'Automobile, running in support of the World Rally Championship. The championship was open to drivers under the age of thirty—although no such restriction existed for co-drivers—competing in identical one-litre Ford Fiesta R2s built and maintained by M-Sport. The championship began in April 2021 at the Croatia Rally.

Tom Kristensson and Joakim Sjöberg were the defending drivers' and co-drivers' champions while Sweden was the defending Nations' Trophy winner. Sami Pajari and Marko Salminen became the first Finnish crew to win the championship. Finland took the Nations' Trophy victory.

The FIA Junior WRC Championship titles were not awarded in 2022, with WRC3 Junior titles taking their place. However, FIA Junior WRC titles would make a return in 2023.
