Swimming at the 2024 Summer Olympics – Qualification

The qualifying phase for swimming at the 2024 Summer Olympics occurred between 1 March 2023 and 23 June 2024. 852 athletes qualified for 35 swimming pool events at the Games, with 57 more qualifying for the 10-kilometre open water marathon swims.

Athletes qualified for the individual swimming pool events through achieving World Aquatics' specified time standards. They could also qualify through universality places, which allowed each National Olympic Committee to enter some athletes regardless of their qualification time, to ensure a wide range of nations were included. National teams qualified for the relay events through their performances at the 2023 or 2024 World Championships, as did the individual qualifiers for the marathon swimming events.

Qualification processes

Individual events

Each National Olympic Committee (NOC) was permitted to enter a maximum of two qualified athletes in each individual event, but only if both of them had attained the Olympic Qualifying Time (OQT). After accepting the two athletes from each NOC who achieved the OQT, World Aquatics considered athletes who had only qualified in a relay event, and then athletes qualifying through universality: NOCs were given one event entry for each gender, which could be used by any athlete regardless of qualification time, as long as no swimmer from that nation had already taken a spot by achieving the OQT.^[a] Finally, the rest of the spaces were filled by athletes who had met the Olympic Consideration Time (OCT).^[1]

The event OQTs corresponded to the time achieved by the fourteenth-place swimmer in their preliminary heat at the previous Games, while the OCTs were derived by adding 0.5% onto the OQT.^[2]

The qualifying time standards had to have been achieved at one of the international meets approved by World Aquatics between 1 March 2023, and 23 June 2024. These included the 2023 and 2024 World Championships, continental meets, national championships and selection trials, and some other competitions approved by World Aquatics.^[2]

Notes

1. NOCs were subject to some other restrictions on who they could pick to fill their universality places.
2. Because the fourteenth-place swimmer achieved a standard slower than the OQT in Tokyo 2020, Tokyo's OQT was used instead.
3. In response to the Russian invasion of Ukraine, Russian and Belarusian athletes were banned from representing their country at the Games. Athletes from these countries were allowed to compete as Individual Neutral Athletes if the met the eligibility criteria, which included that they had not shown any support for the war.^[6]
4. If a continental place was not used, the slot was reallocated to the fastest unqualified swimmer at the 2024 World Aquatics Championships.
5. If a French swimmer already qualified, their slot was reallocated to the fastest unqualified swimmer at the 2024 World Aquatics Championships.
6. Unused continental quota place
7. Unused host quota place
