The Women's 50 metre backstroke competition at the 2024 World Aquatics Championships was held on 14 and 15 February 2024.

Qualification

Each National Federation was permitted to enter a maximum of two qualified athletes in each individual event, but only if both of them had attained the "A" standard qualification time at approved qualifying events. For this event, the "A" standard qualification time was 28.22 seconds. Federations could enter one athlete into the event if they met the "B" standard qualification time. For this event, the "B" standard qualification time was 29.21. Athletes could also enter the event if they had met an "A" or "B" standard in a different event and their Federation had not entered anyone else. Additional considerations applied to Federations who had few swimmers enter through the standard qualification times. Federations in this category could at least enter two men and two women into the competition, all of whom could enter into up to two events.
