Swimming is a key event at the Summer Olympic Games, featuring male and female athletes competing in 16 recognized events each. These competitions take place in a 50-meter pool, known as a long course pool. Swimming can be both an individual and a team sport, and it includes events in freestyle, backstroke, breaststroke, and butterfly. It is one of the most popular Olympic sports.

Recreational swimming dates back to prehistoric times, with evidence found in Stone Age paintings from about 10,000 years ago. Written references to swimming appear as early as 2000 BC, including texts such as the Iliad, the Odyssey, the Bible, Beowulf, and the Quran.

Men's swimming was included in the first modern Olympic Games in Athens in 1896. In 1902, Australian swimmer Richmond Cavill introduced the front crawl to the Western world. Women's swimming events were added to the Olympics in 1912. The butterfly stroke, initially a variant of breaststroke, was developed in the 1930s and recognized as a separate style in 1952.
