# 2021 FIVB Volleyball Girls' U18 World Championship

The 2021 FIVB Volleyball Girls' U18 World Championship was the 17th edition of the FIVB Volleyball Girls' U18 World Championship, contested by the women's national teams under the age of 18 of the members of the Fédération Internationale de Volleyball (FIVB), the sport's global governing body. The final tournament was held in Durango City, Mexico. Mexico were chosen as the hosts for this event for the second time after previously hosting the 2007 tournament.
United States were the defending champions, but lost in the semifinals to Italy.

## Qualification

A total of 20 teams qualified for the final tournament. In addition to Mexico who qualified automatically as hosts, the other 19 teams qualified from five separate continental competitions, which were held by 31 December 2020 at the latest. However, due to the ongoing global COVID-19 pandemic and subsequent impact on some Confederations’ ability to organise the events within the given deadline, the FIVB has decided to postpone the deadline for continental qualifications to 28 February 2021. Additionally, in the case of no Continental Confederations being able to hold qualifying event, teams qualified according to the respective Continental Rankings.
