The women's 100 metre breaststroke event at the 2020 Summer Olympics was held from 25 July to 27 July 2021 at the Tokyo Aquatics Centre.[1][2] It was the event's fourteenth consecutive appearance, having been held at every edition since 1968.

Summary

The U.S.' teen Lydia Jacoby upset South Africa's Tatjana Schoenmaker and defending champion Lilly King to capture the sprint breaststroke title. Hanging with the leaders at the turn, Jacoby broke away over the final 20 metres to win gold by almost three tenths of a second in 1:04.95. With the performance, Jacoby became just the sixth woman in history to break the 1:05 barrier. First at the turn, Schoenmaker could not contend with Jacoby's blistering final lap and settled for silver in a time of 1:05.22, 0.4 seconds shy off her Olympic record in the heats. Meanwhile, Jacoby's teammate and 2016 champion Lilly King was 0.03 seconds ahead of Jacoby at the turn but could not fend off the youngster's charge, taking bronze in 1:05.54.

ROC's Evgeniia Chikunova delivered a time of 1:05.90 to pick up the fourth spot, just ahead of teammate and defending silver medallist Yuliya Yefimova (1:06.02) by about a tenth of a second. Sweden's Sophie Hansson placed sixth in 1:06.07, while Martina Carraro (1:06.19) and Ireland's Mona McSharry (1:06.94) rounded out the championship field.
