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. 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.

The aquatics discipline of swimming is considered the flagship event at every edition of the World Aquatics Championships since its introduction in 1973. While open water swimming events were added to the program in 1991, it is considered a separate discipline to swimming.
