IROC VIII was the eighth year of IROC competition, which took place in 1984. It saw the use of the Chevrolet Camaro in all races, and was the first incarnation of the IROC format in which twelve drivers from different series compete in all four races. Races one and four took place at Michigan International Speedway, while race two took place at Burke Lakefront Airport, and race three ran on the Talladega Superspeedway. Cale Yarborough won one race en route to the championship and $150,000.
This season was the first of three straight that television coverage was on CBS.
