The 2019 Rally de Portugal was a motor racing event for rally cars that was held over four days between 30 May and 2 June 2019. It marked the fifty-third running of Rally de Portugal, and was the seventh round of the 2019 World Rally Championship, World Rally Championship-2 and the newly-created WRC-2 Pro class. The rally was also part of the Portuguese national championship and Peugeot Rally Cup Ibérica. The 2019 event was based in Matosinhos in Porto and consisted of twenty special stages totalling 311.47 km (193.54 mi) competitive kilometres.

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.
