The 2005–06 ISU Junior Grand Prix was the ninth season of the ISU Junior Grand Prix, a series of international junior level competitions organized by the International Skating Union. It was the junior-level complement to the Grand Prix of Figure Skating, which was for senior-level skaters. Skaters competed in the disciplines of men's singles, ladies' singles, pair skating, and ice dance. The top skaters from the series met at the Junior Grand Prix Final. Skaters who reached the age of 13 by July 1, 2005 but had not turned 19 (singles and females of the other two disciplines) or 21 (male pair skaters and ice dancers) were eligible to compete on the junior circuit.
