The 2021 IBJJF World Jiu-Jitsu Championship was the first season of the World Jiu-Jitsu Championship, the most prestigious event in the sport, to take place following the 2019 IBJJF World edition. The previous 2020 edition was cancelled by the organising International Brazilian Jiu-Jitsu Federation as a consequence of the COVID-19 pandemic. This 25th edition took place for the first time at the Anaheim Convention Center in Anaheim, California instead of the Walter Pyramid in Long Beach where it had been held since 2007 after moving from Brazil to the United States. This edition also took place for the first time at the end of the year instead of the beginning of the year like previous edition, giving more time for athletes to be able to participate. The black belts competition took place towards the end, on 11 December and 12 December (two days); the elimination round and the open class / absolute division matches took place on the first day, Saturday 11 December followed by the quarterfinals all the way to the finals on Sunday 12 December, the last day of the tournament. This Championship saw Checkmat winning its first world team title, Dream Art competing for its first year as a team and a new generation of black belts winning their first gold medals, such as Tainan Dalpra who was the first black belt to represent Art Of Jiu Jitsu (AOJ) at the IBJJF World final.
