This list includes manufacturers and teams that entered the World Rally Championship for Manufacturers in the seasons where it was necessary to register or nominate teams. A true list of all marques entered over the entire WRC history could potentially number into the hundreds, indeed the FIA historic database of homologated cars includes thousands of models from hundreds of manufacturers up to 2006, many of which would have been eligible for inclusion. Cars from 34 different manufacturers entered the very first WRC event alone, the 1973 Monte Carlo Rally.
