The 2021 World Artistic Gymnastics Championships will be held at the Kitakyushu City General Gymnasium in Kitakyushu, Japan on October 18-24, 2021. Copenhagen, Denmark was confirmed as the host city in March 2018, but withdrew in July 2020 due to the COVID-19 pandemic. This also marked the first time since 1996 that the Olympics and World Championships were held in the same year.
All participating gymnasts, including those who were not part of a team, participated in a qualification round. The results of this competition determined which teams and individuals participated in the remaining competitions, which included:
The all-around competition, in which only the twenty-four highest scoring individuals in the all-around competed. Each country was limited to only two gymnasts in the all-around final.
The event finals, in which the eight highest scoring individuals on each apparatus competed. Each country was limited to two gymnasts in each apparatus final.
