The Moto4 Asia Cup, formerly known as the Asia Talent Cup, is a motorcycle road racing competition intended for young riders in Asia and Oceania. Organized by Dorna Sports, the promoter of the international Grand Prix motorcycle racing and Superbike World Championship series, the Cup had its inaugural season in 2014 after being founded the year prior. The championship will run under the Idemitsu Moto4 Asia Cup moniker from the 2026 season onwards, with sponsorship from Idemitsu, having previously been contracted with Shell Advance between 2014 and 2016. Alberto Puig has served as Director of the Cup since its inception in 2014.
Ai Ogura and Somkiat Chantra are the only Cup graduates to have raced in the top-flight MotoGP World Championship, in 2025.
