The men's 100 metre freestyle event at the 2025 World Aquatics Championships was held from 30 to 31 July 2025 at the World Aquatics Championships Arena at the Singapore Sports Hub in Kallang, Singapore.

Background Seven of the eight 2024 Olympic finalists were competing, including World Record holder Pan Zhanle of China and Romania’s David Popovici. Pan broke the World Record twice in 2024, setting it at 46.40 seconds, and he won the event at the Olympics and 2024 World Championships, while Popovici ranked second all-time after posting a time of 46.71 at the 2025 European U23 Championships.

Australia’s Kyle Chalmers, the 2023 World champion, had swum 47.27 in 2025 and had improved his front-end speed. Brazil’s Guilherme Caribé ranked third in the world with 47.10. Americans Jack Alexy and Patrick Sammon qualified with times of 46.99 and 47.47 respectively, and both had swum in several major meets in 2025. Egor Kornev of Russia, representing the Neutral Athletes B team; Maxime Grousset of France; and Matt Richards of Great Britain were also key contenders. Josha Salchow of Germany, who reached the final at the 2024 Olympics, was also competing. The field included five of the top ten swimmers in history and six swimmers who had swum under 47.5 in 2025.

Qualification Each National Federation was permitted to enter a maximum of two qualified athletes in each individual event, but they could do so only if both of them had attained the "A" standard qualification time at approved qualifying events. For this event, the "A" standard qualification time was 48.34 seconds. Federations could enter one athlete into the event if they met the "B" standard qualification time. For this event, the "B" standard qualification time was 50.03 seconds. Athletes could also enter the event if they had met an "A" or "B" standard in a different event and their Federation had not entered anyone else. Additional considerations applied to Federations who had few swimmers enter through the standard qualification times. Federations in this category could at least enter two men and two women to the competition, all of whom could enter into up to two events. +Top 10 fastest qualification timesSwimmerCountryTimeCompetitionPan Zhanle46.402024 Summer OlympicsJack Alexy46.992025 United States ChampionshipsGuilherme Caribé47.102025 Brazilian ChampionshipsKyle Chalmers47.272025 Bergen Swim FestivalDavid Popovici47.302025 Romanian ChampionshipsMaxime Grousset47.332024 French Elite ChampionshipsEgor Kornev   Neutral Athletes B47.422025 Russian ChampionshipsPatrick Sammon47.472025 United States ChampionshipsNándor Németh47.492024 European ChampionshipsFlynn Southam47.692025 Australian Trials
