The World Blitz Chess Championship 2021 is a chess tournament held 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 Narodowy Stadium in Warsaw between 29-30 December 2021, using a Swiss-system with 21 rounds for the open tournament and 17 rounds for the women's tournament. Players eligible to participate 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 3+2, meaning each player initially starts with 3 minutes and gains 2 seconds increment with each move.
