Swimming at the 2024 Summer Olympics – Men's 50 metre freestyle

Prior to this competition, the existing world and Olympic records were as follows:

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).^[4] For this event, the OQT was 21.96 seconds. World Aquatics then filled the rest of the event places with athletes qualifying through universality; NOCs were given one event entry for each gender, which could be used by any athlete regardless of qualification time, providing the spaces had not already been taken by athletes from that nation who had achieved the OQT.^[4][5] In total, 40 athletes qualified through achieving the OQT, while 35 athletes qualified through universality places.^[5]
