Swimming at the 2024 Summer Olympics – Women's 100 metre freestyle

The women's 100 metre freestyle event at the 2024 Summer Olympics will be held on 30 and 31 July 2024 at the Olympic Aquatics Centre at Paris La Défense Arena.^[1]

Records

Prior to this competition, the existing records were as follows.

Record	Time	Name	Nation	Event	Date	Notes
World	51.71	Sarah Sjöström	Sweden	2017 Worlds	23 July 2017
Olympic	51.96	Emma McKeon	Australia (AUS)	2020 Tokyo	30 July 2021

Qualification

A National Olympic Committee (NOC) may enter a maximum of two qualified athletes in each individual event, but only if both of them have attained the Olympic Qualifying Time (OQT). One athlete per event can potentially enter if they meet the Olympic Consideration Time (OCT), or if the total quota of 852 athletes has not been targeted. NOCs may also permit swimmers regardless of time (one per gender) under a Universality place since they have no swimmers attaining either of the standard entry times (OQT/OCT).^[2][3]

Following the end of the qualification window, World Aquatics will assess the number of swimmers who have achieved the OQT, the number of relay-only swimmers, and the number of Universality places, before inviting those with OCT to fulfill the total quota of 852. Additionally, OCT places will be distributed by event according to the position of the World Aquatics Rankings during the qualifying deadline.^[2]

Time standards

The qualifying time standards must be obtained at the 2023 and 2024 World Championships, continental championships, continental swimming meets, national championships and selection trials, and various international meets approved by World Aquatics in the period between 1 March 2023 and 23 June 2024.^[4]

The following table outlines the qualifying time standards for Paris 2024 for this event:

* OQTs correspond to the time achieved by a fourteenth-place swimmer in his or her respective preliminary heat of each event at the previous Games.

ª Because the fourteenth-place swimmer achieved a standard slower than the OQT in Tokyo 2020, the OQT used at the previous Games will remain constant.

^ OCTs are derived by adding 0.5% of the OQT standard.

Competition format

The competition consists of three rounds: heats, semifinals, and a final. The swimmers with the best 16 times in the heats advance to the semifinals. The swimmers with the best 8 times in the semifinals advance to the final. Swim-offs are used as necessary to break ties for advancement to the next round.

Schedule

All times are Central European time (UTC+1)^[1]
