The 2010 GP3 Series season was the first season of the GP3 Series, a feeder series for the GP2 Series. The championship was contested over sixteen races held at eight rounds, beginning on 8 May at Circuit de Catalunya and ending on 12 September at Autodromo Nazionale Monza. Ten teams were announced, running three cars each.
The inaugural title was claimed by ART Grand Prix driver Esteban Gutiérrez, having taken the final pole position of the season at Monza to put him out of reach of title rival Robert Wickens. Gutiérrez took five race wins during the season, four of which coming in the higher points-rewarding races held on Saturdays. He also took four further podium finishes en route to a 17-point championship win over Wickens. Wickens eventually ended the season with three victories at Hockenheim, Spa-Francorchamps – despite spinning in wet conditions and damaging the nose of his Status Grand Prix car against the pit wall – and Monza, as well as four second place finishes, two of which being behind Gutiérrez.
Nico Müller finished in third position for Jenzer Motorsport, taking victories in Valencia and at the Hungaroring. He finished 15 points clear of Gutiérrez's team-mate Alexander Rossi, who took wins from pole position in the sprint races in Barcelona and at the Hungaroring. Rio Haryanto was fifth for Manor Racing, winning in Istanbul from a reverse-grid pole position. Other victories were taken by Status Grand Prix's Daniel Morad at Silverstone, Pål Varhaug won the season-opening race in Barcelona and Adrien Tambay won from 27th on the grid at Spa in a wet/dry race. ART Grand Prix also claimed the teams' championship, having done so at Spa-Francorchamps, finishing 44 points clear of nearest challengers Status Grand Prix, while Jenzer Motorsport finished in third position ahead of Manor Racing.
