The women's 200 metre breaststroke event at the 2020 Summer Olympics was held from 28 to 30 July 2021 at the Tokyo Aquatics Centre.

South Africa's Tatjana Schoenmaker came from behind to become her nation's first Olympic champion in this event since Penny Heyns in 1996.

Meanwhile, King's teammate Annie Lazor (2:20.84) had the fastest final lap in the field, edging out ROC's Evgeniia Chikunova (2:20.88) by four one-hundredths of a second to claim bronze.

Up to two swimmers per National Olympic Committee (NOC) can automatically qualify by swimming that time at an approved qualification event.

Up to one swimmer per NOC meeting that time is eligible for selection, allocated by world ranking until the maximum quota for all swimming events is reached.
