The 2021 Formula Regional Americas Championship powered by Honda was the fourth season for the FIA Formula 3 regional series across North America, and the second season under the Formula Regional moniker after a rebrand in 2020. The series was sanctioned by SCCA Pro Racing, the professional racing division of the Sports Car Club of America. Drivers competed to win a Honda-backed Super Formula seat in 2022.[1]
Kyffin Simpson took the drivers' championship at the last round at the Circuit of the Americas, while TJ Speed Motorsports secured the teams' title.
