2021 WRC2 Championship

The 2021 FIA WRC2 Championship was the ninth season of WRC2, a rallying championship for organised and governed by the Fédération Internationale de l'Automobile as the second-highest tier of international rallying. The category was open to cars entered by teams and complying with Rally2 regulations. The championship began in January 2021 with the Rallye Monte-Carlo and concluded in November 2021 with Rally Monza, and ran in support of the 2021 World Rally Championship.

Mads Østberg and Torstein Eriksen were the defending 2020 drivers' and co-drivers' champions. Toksport WRT were the defending teams' champions.

Andreas Mikkelsen was crowned 2021 drivers' champion at the penultimate round despite not competing there. As he had used different co-drivers through the season a co-driver of a different crew would therefore become co-driver champion. Torstein Eriksen, consistent co-driver of Mads Østberg, was able to retain his championship title. Movisport became the teams' champion.

The 2021 championship was contested over twelve rounds in Europe and Africa:

With the addition of Rally Chile to the calendar in 2019, the FIA opened the tender process for new events to join the championship in 2020. Three events were successful, but the championship was affected by a series of cancellations in 2019 and 2020 that necessitated changes to the 2021 calendar:

In light of the disruption caused by the pandemic in 2020 and in anticipation of further delays, the calendar included an additional six reserve rounds that could be included in the event of rallies being cancelled. These events include rallies in Turkey, Argentina and Latvia. The Ypres Rally had also been included on this reserve list before it replaced Rally GB, so as the Acropolis Rally and Rally Monza.
