The 2020 NTT IndyCar Series was the 25th season of the IndyCar Series and the 109th official championship season of American open-wheel racing. The premier event was the 2020 Indianapolis 500. Josef Newgarden entered the season as the defending National Champion. Honda entered as defending Manufacturers' Cup champion for the second consecutive season. It was the first year under Penske management after they took over in late 2019.

Series news On May 24, 2019, it was announced that the IndyCar Series would introduce cockpit protection, combining an Aeroscreen and the Halo used in Formula One, from the 2020 season onwards. The cockpit protection was built by Red Bull Advanced Technologies in a collaborative effort with Dallara. The combination of aeroscreen and halo is designed to improve safety standards by deflecting debris away from a driver's head and was originally developed for use in Formula One and IndyCar before its application was expanded to other open-wheel championships. On November 3, 2019, it was announced the Team Penske owner Roger Penske had purchased IndyCar, LLC and the Indianapolis Motor Speedway. Penske also announced he will step down as full-time race strategist. On January 6, 2020, IndyCar announced the transactions were formally complete. Penske officially becomes just the fourth owner in Indianapolis Motor Speedway's history and marks the first time since 1945 where ownership of the Speedway has changed hands.

Confirmed entries The following teams, entries, and drivers have been announced to compete in the 2020 NTT IndyCar Series season. All teams will use a spec Dallara DW12 chassis with UAK18 aero kit and Firestone tires.
