The Junior World Championships in artistic gymnastics were first held in 2019. Originally meant to be held every two years, the second edition of the event was not held until 2023 due to the COVID-19 pandemic.

Three medals are awarded: gold for first place, silver for second place, and bronze for third place. Tie breakers were used in the first year of the event but were not used subsequently.
