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.

Ralliart is the high-performance division of Mitsubishi Motors. It was responsible for development and preparation of the company's rally development of high-performance models and parts available to the public. Ralliart scaled down its business activities in April 2010, though the brand will continue to be used by Mitsubishi.
