2021 GT Cup Open Europe

The 2021 GT Cup Open Europe was the third season of the GT Cup Open Europe, the grand tourer-style sports car racing series founded by the Spanish GT Sport Organización. It began on 15 May at Paul Ricard and finished on 24 November at the Circuit de Barcelona-Catalunya after five double-header meetings.

Race calendar and results

 * A provisional six-round calendar was revealed on 12 January 2021. It represents a return to normalcy after the Coronavirus pandemic forced change in the 2020 season. After being added to the previous year's revised calendar as a replacement round, the Hungaroring was originally dropped from the 2021 schedule in favor of Portimão. Due to a late schedule change for Formula 1 however, this decision was reversed. The other tracks carry over from the previous year, but on different dates.

Points systems
Points are awarded to the top 10 (Overall) or top 6 (Am, Pro-Am, Teams) classified finishers. If less than 6 participants start the race or if less than 75% of the original race distance is completed, half points are awarded. At the end of the season, the lowest race score is dropped; however, the dropped race cannot be the result of a disqualification or race ban.

Teams' Championship
Only the highest two finishing cars from a team count towards the Teams' Championship
