The 2025 World Junior Figure Skating Championships were held from February 25 to March 2, 2025, at the Főnix Aréna in Debrecen, Hungary. The competition determined the entry quotas for each skating federation at the 2026 World Junior Championships. Medals were awarded in men's singles, women's singles, pair skating, and ice dance.

Skaters were eligible for the 2025 World Junior Championships if they turned 13 years of age before July 1, 2024, and if they have not yet turned 19 (singles) or 21 (ice dancers and female pairs skaters) or 23 (male pairs skaters).

Additionally, skaters had to meet the minimum technical elements score requirements. The ISU accepted scores if they were obtained at junior-level ISU-recognized international competitions during the ongoing or preceding season, no later than 21 days before the first official practice day.

Based on the results of the 2024 World Junior Championships, each ISU member nation could field between one and three entries per discipline.

Member nations started announcing their entries in December 2024. The International Skating Union released the official list of entrants on January 29, 2025.
