The World Table Tennis Championships are table tennis competitions sanctioned by the International Table Tennis Federation (ITTF). The World Championships have been held since 1926, biennially since 1957. Five individual events, which include men's singles, women's singles, men's doubles, women's double and mixed doubles, are currently held in odd numbered years. The World Team Table Tennis Championships, which include men's team and women's team events, were first their own competition in 2000. The Team Championships are held in even numbered years.

Table tennis is a racket sport derived from tennis but distinguished by its playing surface being atop a stationary table, rather than the court on which players stand. Either individually or in teams of two, players take alternating turns returning a light, hollow ball over the table's net onto the opposing half of the court using small rackets until they fail to do so, which results in a point for the opponent. Play is fast, requiring quick reaction and constant attention, and is characterized by an emphasis on spin relative to other ball sports, which can heavily affect the ball's trajectory.
