The 1973 World Rally Championship season was the inaugural season for the Fédération Internationale de l'Automobile (FIA) World Rally Championship (WRC) format. It consisted of 13 events, each held in a different country of the world. Many of the events would be staples of the series through to today, including Monte Carlo, Sweden, Tour de Corse, and the RAC Rally, while others would soon be replaced in the schedule. As with following seasons, gravel events formed the majority of the schedule. Two pure tarmac and one snow and ice rally were also included, as well as three events held on a mixture of soft and hard surface roads.
