The 1986 World Rally Championship was the 14th season of the Fédération Internationale de l'Automobile (FIA) World Rally Championship (WRC). The season consisted of 13 rallies, including all twelve venues of the previous season as well as the addition of the Olympus Rally. This marked the return of the WRC to the United States and North America, as well as the first world rally to be held on the western side of the continent. The December rally would also be the only WRC event to feature Group B competition in the United States.

The World Rally Championship is an international rallying series owned and governed by the FIA. Inaugurated in 1973, it is the second oldest of the FIA's world championships after Formula One. Each season lasts one calendar year, and separate championship titles are awarded to drivers, co-drivers and manufacturers. There are also two support championships, WRC2 and WRC3, which are contested on the same events and stages as the WRC, but with progressively lower maximum performance and running costs of the cars permitted. Junior WRC is also contested on five events of the World Rally Championship calendar.
