The men's 4 × 100 metre medley relay at the 2025 World Aquatics Championships was held on 3 August 2025 at the World Aquatics Championships Arena at the Singapore Sports Hub in Kallang, Singapore.
Background The event had no clear favourite for gold. China were looking to win their first world title in this event, returning most of their Olympic-winning team. Xu Jiayu was expected to start strongly, Qin Haiyang had been the fastest breaststroker in 2025, and Pan Zhanle was regarded as the best anchor in the field. The Neutral Athletes B team, which consists entirely of athletes from Russia, had set a national record of 3:28.49 earlier in the year, with Kliment Kolesnikov, Kirill Prigoda, Andrei Minakov and Egor Kornev forming the team. The United States had a weak backstroke leg but also held the fastest combined times of 2025. France, led by Yoann Ndoye-Brouard, Léon Marchand and Maxime Grousset, and Italy, led by Thomas Ceccon and Nicolò Martinenghi, were also in contention for medals.
Qualification Each National Federation could enter one team in the relay. The team had to be composed of swimmers who were also competing in the individual events, along with relay only swimmers who had to have met a specific qualifying time for the corresponding stroke and distance they would be swimming in the relay. Federations were only allowed to enter two relay-only swimmers for each relay they entered, though they could also enter relay-only swimmers from other relays which did not count toward this limitation.
