Mollie O'Callaghan
Australian swimmer (born 2004)
Mollie Grace O'Callaghan OAM (born 2 April 2004) is an Australian swimmer and the reigning Olympic champion in the 200 m freestyle . She was the 2023 world champion in the women's 100m and 200m freestyle individual events, and part of the world champion 4 × 100 m and 4 × 200 m Australian women's relay teams together with 4 × 100 m mixed relay team. She previously held the world record in the women's individual 200m freestyle.
O'Callaghan also won two gold and one bronze medals at the 2020 Summer Olympics as a heats swimmer in relay events and gold medal in the 200 m freestyle and 4 × 100 metre freestyle relay at the 2024 Summer Olympics .
2020 Tokyo Olympics
O'Callaghan swam for the Australian team in the preliminaries of all three women's relays at the 2020 Summer Olympics in Tokyo , receiving two gold medals and one bronze for her contribution. Swimming the 1st leg for Australia in the heats of the 4 × 100 metre freestyle relay , she posted a time of 53.08 and received a gold medal after the Australian team won the final.[ 2]
In the 4 × 200 metre freestyle relay preliminaries, O'Callaghan swam a
junior world record of 1:55.11 when swimming the lead off leg. Her time would have placed her fifth in the
200 metre freestyle final.[ 3] However, because the Australian coaches had previously decided to use four fresh swimmers in the final, O'Callaghan was controversially not selected for the final where Australia finished third.[ 4]
In a heat of the 4 × 100 metre medley relay , O'Callaghan again posted
a competitive time; her anchor leg split was 52.35, only 0.24 seconds slower than the fastest freestyle split in the final by Cate Campbell .
2023 World Aquatics Championships
At the 2023 World Aquatics Championships , O'Callaghan was a world champion in five events.
O'Callaghan won the women's 100m freestyle in 52.16, after qualifying in second place, and the women's 200m freestyle in a world record time of 1:52.85 after qualifying in third place. She was the first woman to win both of these events in a single world championship.[ 5]
O'Callaghan was also part of three champion relay teams, each of which set a world-record time: the women's 4 × 100 m freestyle relay;[ 6] the women's 4 × 200 m freestyle relay;[ 7] and the mixed 4 × 100 m freestyle relay.[ 8]
