The 2015 FIA Formula 3 European Championship was a multi-event motor racing championship for single-seat open wheel formula racing cars that was held across Europe. The championship featured drivers competing in two-litre Formula Three racing cars which conform to the technical regulations, or formula, for the championship. It was the fourtth edition of the FIA Formula 3 European Championship .
Esteban Ocon was the reigning drivers' champion, but he did not defend his title as he moved across to the GP3 Series. His team, Prema Powerteam, was the defending winners of the teams' championship.
The following teams and drivers are scheduled to compete during the 2015 season:
A provisional eleven-round calendar was announced on 4 December 2014. The series will return to Zandvoort (replacing the Hungaroring) after a one-year absence, while the Italian round has been moved from Autodromo Enzo e Dino Ferrari to Monza, still supporting the Italian GT Championship. On 3 May 2015, was announced that round at Moscow Raceway will be changed to Algarve International Circuit.
The second and third races at Monza (both for safety car incidents) and the third race at Spielberg (rain) were red-flagged after three laps were completed, but before 75% of the scheduled distance in laps, the necessary distance required for a race to pay full points. All three races paid half points to all classified finishers.
At Monza, the second race was red-flagged on Lap 14 of 19, with 2:20 remaining in the 35-minute race, as the Safety Car would have resulted in the race ending under caution because of multiple Safety Car periods caused by incidents. The excessive number of incidents during the race resulted in a warning by officials during the drivers' meeting of proper driver conduct before the start of the third race. A start crash involving Ryan Tveter and Fabian Schiller resulted in officials imposing an ultimatum that drivers be on their best behaviour or the race would be abandoned. On lap six Lance Stroll and Mikkel Jensen collided causing the race to be red-flagged three laps later. As a result, series organisers awarded half points to each of the classified finishers eligible to score points.
