The 2012 GP3 Series season was the third season of the GP3 Series, a feeder series for the GP2 Series. The season began at Barcelona on 12 May and concluded at Autodromo Nazionale Monza on 9 September after eight rounds made up of two races each and all in support of European Formula One Grands Prix.
The series adopted the points system used by Formula One for the feature race, with points awarded to the top ten drivers and twenty-five points on offer for victory. The points awarded in the sprint race also were changed, with the winner receiving fifteen points and top eight drivers receiving points. The points awarded for pole position and the fastest lap of the race also were doubled.
The winner of the championship was Mitch Evans driving for the MW Arden team, who outscored Lotus GP driver Daniel Abt by two points.
Ten teams and thirty drivers had been due to take part in the 2012 season. However, in April 2012 it was reported that only twenty-seven drivers would take place with Mücke Motorsport missing from the grid.
The 2012 calendar was announced on 16 December 2011. The series will consist of eight rounds, with a round in Monaco confirmed on 26 January 2012. The series had previously attempted to include a race in Monaco for the 2011 season, but was forced to abandon its plans when it was found that the support paddock did not have enough space for the GP3 Series. The series will support every Grand Prix on the European leg of the 2012 Formula One season.
Carlin's António Félix da Costa qualified on pole position by 0.01 seconds to Lotus GP drivers Conor Daly and Aaro Vainio. However, on the start of the race their team-mate Daniel Abt made a lightning getaway from seventh grid position to lead. But Abt and Félix da Costa both had a jump start and got drive-through penalty. Returnee Mitch Evans, who was behind the two drivers after the start, won the opening race at Barcelona. Status Grand Prix's Marlon Stöckinger scored his first series podium, finishing second. Vainio completed the podium. Conor Daly recouped in the sprint race, claiming his first series win. Reverse polesitter Robert Visoiu and MW Arden's Matias Laine were also on podium.
