The World Aquatics Swimming Championships (25m), formerly known as the FINA World Swimming Championships (25m), also referred to as 'short course worlds', are an international swimming competition staged by the internationally recognized governing body of the sport, World Aquatics (formerly FINA). The championships are staged in a 25m pool, referred to as short course format, and traditionally have been held biennially in alternate years to the World Aquatics Championships. Unlike the World Aquatics Championships, only swimming events are staged at these championships (being one of the six disciplines that form part of the World Aquatics Championships).
Member federations referred to as winners, second, and third, in the table below, are the top three nation's listed on the medal tally based on the standard method of ranking (being total gold medals, followed by total silver medals, and then total bronze medals).
The 2022 championships were the first edition of the championships in which the male and female event programs were identical. Mixed relays were added from the 2014 edition of the championships.
