50 m butterfly, women, 25 m pool

What to remember

Carmel, in the United States, hosted a World Cup stop on October 11, 2025. Gretchen Walsh swam the short course 50 m butterfly there in 23.72 s.

Butterfly is one of the American's two specialties, alongside freestyle. At the 2024 Paris Olympics she took silver in the 100 m butterfly, after an Olympic record of 55.38 s in the semifinals.

At world level, the 50 m butterfly joined the short course championships in 1999 and the long course ones in 2001. World Aquatics recognises separate records for each pool length.
