The 2019 Blancpain GT Series Endurance Cup was the ninth season of the Blancpain GT Series Endurance Cup. The season began on 14 April at Monza and ended on 29 September in Barcelona. The season featured five rounds, with each race lasting for a duration of three hours besides the 24 Hours of Spa and the 1000 km Paul Ricard events.
At the annual press conference during the 2018 24 Hours of Spa on 27 July, the Stéphane Ratel Organisation announced the first draft of the 2019 calendar. The World Challenge Europe round at the Nürburgring would become an Endurance Cup round, replacing the round in Barcelona, before the two tracks were swapped around again in the final draft of the calendar released on 22 October.
