In offroad racing, various classes of specially modified vehicles, including cars, compete in races through off-road environments. In North America these races often take place in the desert, such as the famous Baja 1000, but the general idea of "offroad racing" can also extend to include hillclimbing or any other form of racing that does not occur on a specified, paved track. In Europe, "offroad" refers to events such as autocross or rallycross, while desert races and rally-raids such as the Paris-Dakar, Master Rallye or European "bajas" are called Cross-Country Rallies.

Some of the more famous offroad racing series include CORR, SCORE International and SODA.
