The 2023 World Junior Figure Skating Championships was held in Calgary, Canada, from February 27 to March 5, 2023. Medals were awarded in men's singles, women's singles, pairs, and ice dance. The competition determined the entry quotas for each federation at the 2024 World Junior Championships.
On March 1, 2022, the ISU banned figure skaters and officials from Russia and Belarus from attending all international competitions due to the 2022 Russian invasion of Ukraine.
Skaters were eligible for the 2023 World Junior Championships if they turned 13 years of age before July 1, 2022, and if they have not yet turned 19 (singles and females of the other two disciplines) or 21 (male pair skaters and ice dancers).
Additionally, skaters must meet the minimum technical elements score requirements. The ISU accepts 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 2022 World Junior Championships, each ISU member nation could field one to three entries per discipline. China did not participate due to COVID-19 protocols, and could only field one entry.
Member nations began announcing their selections in December 2022. The International Skating Union published entries on February 7, 2023.
