2020 Super Taikyu Series

The 2020 Pirelli Super Taikyu Series was the twenty-ninth season of the Super Taikyu Series endurance racing championship. It began with the Fuji Super TEC 24 Hours at Fuji Speedway, which was postponed to 5-6 September due to the effects of the COVID-19 pandemic. It ended on 13 December at Autopolis, after five out of six scheduled rounds.

Mercedes-AMG Team Hirix Racing won the championship in the series' GT3 category, known as ST-X, with a Mercedes-AMG GT3 Evo. It was the team's first and only season in Super Taikyu.

This was the third and final year of Pirelli's contract as the series' official tyre supplier, to be replaced by Hankook Tire beginning in 2021.

Calendar
The Super Taikyu Series announced its initial six-race calendar on 27 November 2019. There were no significant changes from the 2019 schedule, which again featured one round at each of Japan's six major racing circuits.

Mobilityland Corporation, the owner of Suzuka Circuit, announced on 2 March that the opening round, originally scheduled for 21-22 March, had been postponed due to the outbreak of the novel coronavirus. A new calendar was published on 10 June, confirming that the start of the season would be delayed to September. Only the round at Okayama International Circuit, originally intended to host the season finale, would retain its initial date of 31 October-1 November.

The Suzuka round, which had been rescheduled to take place on 24 January 2021, was eventually cancelled on 13 January due to multiple prefectures in the Chūbu region declaring a state of emergency. The Super Taikyu Series officially announced the conclusion of the 2020 season two weeks later on 26 January.

Teams and Drivers
58 cars entered throughout the course of the 2020 season. All entries were registered under a Japanese license.

Championship standings
Championship points were awarded in every class at the end of each event. On 10 June it was announced that each team's five highest-scoring rounds counted towards the final championship standings. The eventual cancellation of the Suzuka round made this change redundant for 2020.
