The Mitsubishi Lancer WRC is a World Rally Car built by Ralliart, Mitsubishi Motors' motorsport division, to compete in the World Rally Championship. The previous Lancer Evolution series were homologated for the Group A class, and their competitiveness against World Rally Cars from other manufacturers was therefore limited.

A World Rally Car is a racing automobile built to the specific regulations set by the Fédération Internationale de l'Automobile (FIA) and designed for competition in the World Rally Championship (WRC). The cars were introduced in 1997 as a replacement for Group A regulations used in the manufacturers' championship, and were replaced by Group Rally1 in 2022.
