The 2019 Monte Carlo Rally was a motor racing event for rally cars that was held over four days between 25 and 28 January 2019. It marked the eighty-seventh running of the Monte Carlo Rally, and was the first round of the 2019 World Rally Championship. It was also the first round of the World Rally Championship-2 and the newly-created WRC-2 Pro class. The 2019 event was based in the town of Gap in the Hautes-Alpes department of France and consists of sixteen special stages. The rally covered a total competitive distance of 322.81 km (200.58 mi).

The 2019 FIA World Rally Championship was the forty-seventh season of the World Rally Championship, a rallying championship recognised by the Fédération Internationale de l'Automobile (FIA) as the highest class of international rallying. Teams and crews competed in fourteen events for the World Rally Championships for Drivers, Co-drivers and Manufacturers. Crews were free to compete in cars complying with World Rally Car and Group R 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 series was once again supported by the World Rally Championship-2 category at every round, which was split into 2 classifications: the World Rally Championship-2 Pro for manufacturer entries and the World Rally Championship-2 for private entries, and by the Junior World Rally Championship at selected events. The World Rally Championship-3 was discontinued in 2018.
