The 2020 Speed Energy Stadium Super Trucks Series was the eighth season of the Stadium Super Trucks and the first in which the series was split into two championships, with the Speed Energy Stadium Super Trucks in the United States and the Boost Mobile Super Trucks in Australia.
Much of the series' calendar after the season-opening Adelaide 500 in February—held as a combination event with the Boost Mobile Super Trucks—was wiped out by the COVID-19 pandemic. After a six-month hiatus, the trucks returned in August at Road America. Standings were not officially tracked by the series, but Robby Gordon was the lone driver to record podium finishes in every race while reigning champion Matthew Brabham won twice.
