Swimming is one of the sports at the quadrennial Commonwealth Games competition. It has been a Commonwealth Games sport since the inaugural edition of the event's precursor, the 1930 British Empire Games. It is a core sport and must be included in the sporting programme of each edition of the Games. Synchronised swimming and Diving events are optional. Water polo is a recognised (i.e. not yet optional) sport.
From the 2002 Commonwealth Games a number of events have been included in the program to include elite athletes with disabilities. Para swimming have been included in every games since.
