2021 AmeriCar Championship Road Racing Series season

The 2021 AmeriCar Championship Road Racing Series season will be the 43rd season of AmeriCar, currently the major road racing series in North America, sanctioned by the National Road Racing Club of America.

Due to the global pandemic that impeded much of the proposed realignment of NRRC racing, AmeriCar gains a 4th class and two associate championships under the ProAmerica name, one for Prototypes and another for Formula cars, bringing the total series to 6, running mostly separate events until the championship finale at the NRRC National Championship Runoffs at Road Atlanta in October.
