The 2019 International GT Open was the fourteenth season of the International GT Open, the grand tourer-style sports car racing series founded in 2006 by the Spanish GT Sport Organización.
It began on 27 April at Le Castellet and will finish on 12 October, at Monza after seven double-header meetings.
Points are awarded to the top 10 (Pro) 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.
