1983 World Rally Championship season

The 1983 World Rally Championship was the 11th season of the Fédération Internationale de l'Automobile (FIA) World Rally Championship (WRC). The season consisted of 12 rallies. By this time, the schedule format had become generally stable, with only one or two changes to venues year to year. 1983 brought the return of Argentina to the schedule in place of Brazil. Audi's Hannu Mikkola beat the defending world champion Walter Röhrl and his Lancia teammate Markku Alén to the drivers' title. Lancia captured the manufacturers' title from Audi by just two points.

German Walter Röhrl, champion of the previous year despite his manufacturer's failed bid to capture the title, was tapped to drive for the Martini Racing team along with Finn Markku Alén in the new Lancia Rally 037 car. Audi Sport meanwhile carried forward from its successful title run in 1982 led by the same pair of drivers, Finn Hannu Mikkola and Frenchwoman Michèle Mouton, equipped with the Quattro A1 (later in the season upgrading to the A2 model). The team also future champion Swede Stig Blomqvist. Rothmans Opel Rally Team tapped former champion Finn Ari Vatanen and fellow countryman Henri Toivonen to drive the Ascona 400 during the season.
