The women's 100 metre breaststroke event at the 2025 World Aquatics Championships WAS held from 28 to 29 July 2025 at the World Aquatics Championships Arena at the Singapore Sports Hub in Kallang, Singapore.
Background China’s Tang Qianting is the favourite for the event, as she won the event at the 2024 World Championships and finished second at the 2024 Olympics. She won the 2025 Chinese Championships in 1:05.57, the second-fastest time this year, and holds the fastest time of 1:04.39 from the past two years. In April, Great Britain’s Angharad Evans swam 1:05.37, which is the fastest time this year. She is aiming for her first major long course medal. Germany’s Anna Elendt ranks third in 2025 with 1:05.72, her fastest since earning silver in 2022.
The USA’s Kate Douglass, Estonia’s Eneli Jefimova, and Italy’s Anita Bottazzo have all swum under 1:06 in 2025 and are close in rankings. Lithuania’s Rūta Meilutytė and the USA’s Lilly King, both former world champions, are in contention but must return to their past form to reach the podium. Other finalists could include Ireland’s Mona McSharry, Russia’s Evgeniia Chikunova, Japan’s Satomi Suzuki, Italy’s Lisa Angiolini, and Belarus’s Alina Zmushka.
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. For this event, the "A" standard qualification time was 1:06.87 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 1:09.21 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 timesSwimmerCountryTimeCompetitionTang Qianting1:04.392024 Chinese ChampionshipsTatjana Smith1:05.002024 Summer OlympicsAngharad Evans1:05.372025 Great British ChampionshipsLilly King1:05.432024 United States Olympic TrialsBenedetta Pilato1:05.44Sette Colli 2024Mona McSharry1:05.512024 Summer OlympicsAnna Elendt1:05.722025 German ChampionshipsLydia Jacoby1:05.74Texas stop of the 2024 TYR Pro Swim SeriesReona Aoki1:05.762024 Japanese Olympic TrialsKate Douglass1:05.792025 United States Championships
