Great Britain at the 2015 World Aquatics Championships

Great Britain competed at the 2015 World Aquatics Championships in Kazan, Russia between 24 July to 9 August 2015.

Tom Daley and Rebecca Gallantree became the first ever winners of the Mixed team event. In doing so, Daley became the first British diver to win multiple medals across World Championships, and the first British double world champion. Gallantree became the first female British diver to win a World Championship medal of any colour, and the first female British World Champion. With bronze in the Men's 10 m platform, Daley would go on to become the first British diver to win three World Championship medals.

Jack Laugher, with his bronze medal in both the Men's 3 m springboard event, and Men's 3 m synchronized springboard with Chris Mears, became the first British diver to win two World championship medals at one edition, later equalled by Daley. With a gold and three bronze medals, the 2015 edition was by some margin the most successful World Championships in diving for Great Britain since the championships began.

With Great Britain's first gold medal in Men's high diving, Gary Hunt brought the Great Britain overall tally to ten medals, the highest ever for the nation at a FINA World Aquatics Championships. Simultaneously, with his silver medal from 2013, Hunt became the most successful male high diver since the event was brought into the World Aquatics Championships.

Adam Peaty became the first British swimmer to ever win three gold medals at a global championships, Worlds or Olympic, with victories in the 50 metre and 100 metre breaststroke events and the 4 x 100 metre mixed medley relay. James Guy won the first ever gold medal in male freestyle for Great Britain at a World Championships in the 200 metres freestyle, and then anchored the Great Britain Men's 4 × 200 m freestyle relay team to its first ever victory in the event.

The bronze medal won by Jaz Carlin in the Women's 800 m freestyle brought the tally of swimming medals to five golds, a silver and three bronzes, at nine medals, the best return for Great Britain in the swimming portion of a World Aquatics Championships, having already achieved the best results in their history in diving and high diving. The full tally of seven golds, one silver and six bronze was also an historic high for the championships as a whole.

Diving
British divers qualified for the individual spots and the synchronized teams at the World Championships. Nine divers have been nominated to the roster for Team GB at the Worlds, including 2012 Olympic bronze medalist Tom Daley.

Diving at the 2015 World Aquatics Championships was a qualification event for the 2016 Summer Olympics, and Great Britain, with a top three finish in the 3 m synchronized springboard for Jack Laugher and Chris Mears, achieved a quota place for a team at the Rio games. In the individual events, Tom Daley (10m platform) and Jack Laugher (3m springboard) both won bronze medals, and they, along with finalists Rebecca Gallantree (3 metre springboard) and Tonia Couch (10 metre platform), won a single quota place for Great Britain in each of the four individual diving events in Rio.
