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. The inclusion of events in this category has been inconsistent over the four Games where they have been included.
