The 2013 FIM Moto3 World Championship was the lightweight class of the 65th Fédération Internationale de Motocyclisme (FIM) Road Racing World Championship season. The riders' championship title was won by Team Calvo rider Maverick Viñales and runner up by Álex Rins from Estrella Galicia 0,0.

Season summary In Moto3, the championship was dominated by three Spanish riders, all riding KTM machinery. Like the premier class, there was a final race title decider between Ajo Motorsport's Luis Salom, Estrella Galicia 0,0's Álex Rins and Maverick Viñales of Team Calvo; if any rider of the three won the race, they finished as the champion, regardless of the other results. After Salom crashed out early in the race, Rins and Viñales battled at the front, with Viñales ultimately coming out as the victor and champion, with Rins being passed for second place on the line by Jonas Folger. With Salom only making it back up to fourteenth, Rins finished as runner-up ahead of Salom. With every race won by a KTM rider – seven wins for Salom, six for Rins, three for Viñales and one for Álex Márquez, the teammate of Rins, at Motegi – the marque was comfortably the winners of the constructors' championship, scoring more than double the points of the next placed constructor, Kalex KTM.
