The World Rapid Chess Championship 2021 is the 2021 edition of the annual World Rapid Chess Championship held by FIDE to determine the world champion in chess played under rapid time controls. Since 2012, FIDE has held the World Rapid and Blitz Championships at a joint tournament. Originally planned to be held in Nur-Sultan, Kazakhstan, new coronavirus restrictions introduced by the Kazakh government prompted FIDE to change the location of the tournament to Warsaw, Poland.
The event took place at the Stadion Narodowy in Warsaw between 26 and 28 December 2021, using a Swiss-system with 13 rounds for the open tournament and 11 rounds for the women's tournament. Players eligible to participate in the open tournament must either be rated at least 2550 Elo in a FIDE rating list during 2021, or be a reigning national champion. Time controls for the tournament are 15+10, meaning each player initially starts with 15 minutes and gains 10 seconds increment with each move.

Buchholz (the sum of the scores of each of the opponents of a player)
Average Rating of Opponents Cut 1 (average rating of opponents excluding the lowest rated opponent)

Drawing of lots
If two or more players are tied for any position other than first, the above mentioned tiebreak system shall decide the ranking of the tied players.
