The 1964 American Road Race of Champions was the first running of the SCCA National Championship Runoffs. It took place on 14 and 15 November 1964 at the Riverside International Raceway. The ARRC was held as the non-championship final round of the SCCA National Sports Car Championship and the SCCA Divisional Championships. Most competitive drivers from SCCA's six divisions were invited to the event. No championships were contested that year as part of the Runoffs, and therefore, ARRC champions were not SCCA National Champions.
A Production & B Production drivers raced in a multi-class race held on November 15 for 45 minutes and 27 laps. There were originally two separate races scheduled, but the entrant number was too low for two races.
The 1964 American Road Race of Champions started a new chapter in the history of American amateur road racing. The National Championship was cancelled for 1965 and the ARRC became the only interdivisional amateur road race. It was still a non-championship event until 1966, when Runoffs winners in each class became National Champions.
