The 2006 World Junior Figure Skating Championships were held in Ljubljana, Slovenia from March 6 to 12.

Skaters competed in four disciplines: men's singles, ladies' singles, pair skating, and ice dancing.

The event was open to figure skaters from ISU member nations who on July 1, 2005, had reached the age of 13 but had not yet turned 19 (or 21 for male pair skaters and ice dancers).

Therefore, some of the skaters competing had competed nationally and internationally at the senior level, but were still age-eligible for Junior Worlds.

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