2023 WRC2 Championship

The 2023 FIA WRC2 Championship was the eleventh season of WRC2, a rallying championship organised and governed by the Fédération Internationale de l'Automobile as the second-highest tier of international rallying. The category was open to crews with cars complying with Group Rally2 regulations. The championship began in January 2023 with the Rallye Monte-Carlo and concluded in November with Rally Japan, and ran in support of the 2023 World Rally Championship.

Emil Lindholm and Reeta Hämäläinen entered as the defending drivers' and co-drivers' champions, while Toksport WRT entered as the defending teams' champions.

Andreas Mikkelsen and Torstein Eriksen became the 2023 WRC-2 champions, their second title victories in the championship. Toksport WRT 3 took victory in the teams' championship.

The 2023 season was contested over thirteen rounds crossing Europe, Africa, North and South America, and Asia.

The championship was expected to be expanded to fourteen rounds from the thirteen rounds in the previous season by WRC Promoter GmbH, with eight Europe-based rallies and six fly-away events covering the season. However, when the calendar was released in late November following a lengthy delay, the number of the events was reduced to thirteen with the anticipated Saudi Arabian rally based at Jeddah, absent from the calendar.

Several rally organizers also expressed their interests to return to the championship, including Rally Argentina, Rally Australia, the German Rally, and an event in Northern Ireland. The Argentine, Australian and Northern Irish bids failed and Germany organized the Central European Rally along with Austria and the Czech Republic. In addition to the candidate events, the WRC Promoter GmbH was also working on the calendar expansion to the Middle East and United States, but no rallies were added for the 2023 season.

The following teams and crews contested the 2023 WRC2. Teams had to enter two crews to be eligible for Teams' Championship points.

The 2022 junior championships of the class, WRC-2 Junior, were renamed as WRC-2 Challenger to focus on the experience of the competitors instead of age, while the Masters series was opened to Rally2, Rally3, Rally4, Rally5 and R-GT competitors under the WRC framework, ceasing to be based on WRC2.
