The 2019 Barcelona FIA Formula 3 round was a motor racing event held on 11 and 12 May 2019 at the Circuit de Barcelona-Catalunya in Spain.

Ten teams were listed to compete in the inaugural season; Reigning GP3 champions ART Grand Prix, Campos Racing, Jenzer Motorsport, MP Motorsport and Trident were chosen from the GP3 Series teams, while Carlin, Hitech Grand Prix, and reigning European F3 champions Prema Racing were chosen from the Formula 3 European Championship.

However, on the cool-down lap, Lundgaard would be awarded a penalty for exceeding the Full Course Yellow speed limit, which would hand the win to Russian driver Shwartzman.

Liam Lawson would also not be classified following a late pit-lane start having suffered a mechanical failure on the warm-up lap.

The start saw four drivers eliminated following a collision at turns 1 and 2; Raoul Hyman, Ye Yifei, Jake Hughes, and Artem Petrov, which brought out the safety car.
