The 2003 World Junior Figure Skating Championships were held from February 24 to March 2 at the Palace of Culture and Sports in Ostrava, Czech Republic.

Medals were awarded in men's singles, ladies' singles, pair skating, and ice dancing.

Due to the large number of participants, the men's and ladies' qualifying groups were split into groups A and B.

The ice dancing qualifying event was split into two groups as well, with both groups doing the same dances in the same order.

The first compulsory dance was the Westminster Waltz, and the second was the Blues.
