2021 World Wrestling Championships

The 2021 World Wrestling Championships was the 17th edition of the World Wrestling Championships of combined events and was held from 2 to 10 October 2021 in Oslo, Norway.
The event was subsequent to the 2019 World Championships due to the cancelation of the 2020 edition during the COVID-19 pandemic. The 2020 Individual World Cup was held as replacement for the World Wrestling Championships.

Participating nations

648 competitors from 66 nations participated.

Under the Court of Arbitration for Sport ban, Russia may not use its name, flag, or anthem and must present themselves as "Neutral Athlete" or "Neutral Team" at any world championships until 16 December 2022. Thus, Russian wrestlers competed under a modified flag and the name "Russian Wrestling Federation" at the 2021 World Championships.

Disappearance of Donald Indrawansa

The manager of Sri Lanka's delegation at the championships was a 45-year-old wrestler from the country named Donald Indrawansa. During the event, on 4 October—the day before he was scheduled to go back home with his team—he suddenly disappeared without any witnesses or traces of him leaving. The rest of his team returned home safely. The Wrestling Federation of Sri Lanka announced it would investigate the incident, but its president said Indrawansa had likely used the trip to illegally immigrate to Europe, and condemned Indrawansa for lacking sportsmanship. His is one of numerous disappearances of Sri Lankans at overseas sporting events.
