The swimming competitions at the 2023 SEA Games took place at Morodok Techo National Aquatics Center in Phnom Penh from 6 to 11 May 2023.^[1]

It was one of four aquatic sports at the Games, along with diving, finswimming and Water Polo.^[2] A total of 39 events was contested at this edition. The 800m/1500m freestyle for men and women was removed respectively, and was replaced with the introduction of the mixed 4X100m medley relay for the first time in SEA Games history.

Singapore once again cemented their swimming dominance in Southeast Asia by a wide margin. Winning 47 medals, consisting of 22 gold, 16 silver and 9 bronze across the competition, the country achieved their best ever away results. Singapore won over half of the gold medals at 22 out of 39, and the country got their 1,000th gold medal at the SEA Games on the pool. One of their swimmers, Jonathan Tan, also achieved Olympic qualification timing for the 2024 Summer Olympics in Paris – while at the same time breaking the Southeast Asian Games record and national record.^[3]
