The ISU Junior Grand Prix of Figure Skating (titled the ISU Junior Series in the 1997–1998 season) is a series of international junior-level competitions organized by the International Skating Union. Medals are awarded in the disciplines of men's singles, ladies' singles, pair skating, and ice dancing. The series was inaugurated in 1997 to complement the senior-level ISU Grand Prix of Figure Skating. Skaters earn qualifying points at each Junior Grand Prix event and the six highest-ranking qualifiers meet at the ISU Junior Grand Prix Final, which is held concurrently with the Grand Prix of Figure Skating Final.
The junior version of the Grand Prix series was established in the 1997–1998 season. There are generally seven qualifying events which lead to a final. All seven hold competitions in men's singles, ladies singles, and ice dancing. Four or five of the events also include a pairs competition. The locations of the ISU Junior Grand Prix events change yearly. The eighth event is the ISU Junior Grand Prix Final. Beginning in the 2008–2009 season, it has been held concurrently with the senior final.
Unlike the senior ISU Grand Prix of Figure Skating, competitors are entered by their national federations rather than seeded by the ISU. The number of entries allotted to each ISU member federation is determined by the country's placements at the previous season's World Junior Championships in each respective discipline.
