Jarmila Kratochvílová

}} Jarmila Kratochvílová (; born 26 January 1951 in Golčův Jeníkov) is a Czechoslovak former track and field athlete. She won the 400 metres and 800 metres at the 1983 World Championships, setting a world record in the 400 m.

In 1983, she set the world record for the 800 metres, which still stands and is currently the longest-standing unshared individual world record in athletics. Only two athletes, Pamela Jelimo of Kenya (2008), and Caster Semenya of South Africa (2018), have come within a second of Kratochvílová's mark since it was set. Provided by Wikipedia
