2023 World Rally Championship

The 2023 FIA World Rally Championship was the 51st season of the World Rally Championship, an international rallying series organised by the Fédération Internationale de l'Automobile (FIA) and WRC Promoter GmbH. Teams and crews competed for the World Rally Championships for Drivers, Co-drivers and Manufacturers. Crews were free to compete in cars complying with Groups Rally1 to Rally5 regulations; however, only manufacturers competing with Rally1 cars homologated were eligible to score points in the manufacturers' championship. The championship began in January 2023 with the Monte Carlo Rally and concluded in November 2023 with the Rally Japan. The series was supported by WRC2 and WRC3 categories at every round of the championship and by the Junior WRC at selected events.

Kalle Rovanperä and Jonne Halttunen were the reigning drivers' and co-drivers' champions, having secured their first championship titles at the 2022 Rally New Zealand. Toyota were the defending manufacturers' champions.

At the conclusion of the championship, Rovanperä and Halttunen won their second World Rally Championship titles at the 2023 Central European Rally. Elfyn Evans and Scott Martin were second, trailing by thirty-four points. Thierry Neuville and Martijn Wydaeghe were third, a further twenty-seven points behind. In the manufacturers' championship, Toyota Gazoo Racing WRT successfully defended their title at the 2023 Rally Chile, holding over-one-hundred-point lead over Hyundai Shell Mobis WRT, with M-Sport Ford WRT in third.

The season was marred by the death of Craig Breen in a pre-event test prior to the 2023 Croatia Rally.

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, drivers and co-drivers contested the championship under Rally1 regulations. All crews use tyres provided by Pirelli.
