The FIA Junior WRC, also known as JWRC and previously known as Junior World Rally Championship, is an international rallying competition restricted to drivers under 29 years old. The championship currently consists of five select rallies of the FIA World Rally Championship (WRC) calendar. The category has been a stepping stone in the careers of Sebastien Loeb and Sébastien Ogier, Dani Sordo, Elfyn Evans, Craig Breen and Thierry Neuville.

The World Rally Championship is an international rallying series owned and governed by the FIA. Inaugurated in 1973, it is the second oldest of the FIA's world championships after Formula One. Each season lasts one calendar year, and separate championship titles are awarded to drivers, co-drivers and manufacturers. There are also two support championships, WRC2 and WRC3, which are contested on the same events and stages as the WRC, but with progressively lower maximum performance and running costs of the cars permitted. Junior WRC is also contested on five events of the World Rally Championship calendar.
