The World Rapid Chess Championship is a chess tournament held to determine the world champion in chess played under rapid time controls. Prior to 2012, FIDE gave such recognition to a limited number of tournaments, with non-FIDE recognized tournaments annually naming a world rapid champion of their own. Since 2012, FIDE has held an annual joint rapid and blitz chess tournament and billed it as the World Rapid & Blitz Chess Championships. FIDE also holds the Women's World Rapid & Blitz Chess Championship. The current rapid world champion is grandmaster Magnus Carlsen. Anastasia Bodnaruk from Russia is the current women's rapid world champion. Carlsen has won the event a record five times.
