The 2013 GP3 Series was the fourth season of the GP3 Series, a motor racing championship that acted as a third-tier feeder series for Formula One and sister series GP2.

The season introduced a new car, the GP3/13, built by Italian racing car manufacturer Dallara. The engine was upgraded to a naturally-aspirated 400bhp V6 unit supplied by AER, and the car also featured a new nose, sidepods and engine cover. The car was estimated to be three seconds per lap than the previous chassis, which was proven correct during pre-season testing.

The championship title was secured by Daniil Kvyat with a race to spare after three consecutive feature race wins in Spa, Monza and Abu Dhabi. He had a thirty-point advantage on ART Grand Prix's Facu Regalia, who finished as runner-up. Regalia's teammate Conor Daly, who was the feature race winner at Valencia, finished in third. Tio Ellinas, who led the drivers' standings until the first race at Spa, bookended the season with victories in both the first race and the final race of the season to finish fourth. Jack Harvey completed the top five, helping ART Grand Prix to claim the teams' championship.
