Florence Griffith-Joyner (born Florence Delorez Griffith), also known as Flo-Jo (December 21, 1959 – September 21, 1998) was an American track and field athlete. She is considered the "fastest woman of all time" based on the fact that she still holds the world record for both the 100 metres and 200 metres, both set in 1988 and never seriously challenged. She died due to epilepsy in 1998 at the age of 38.
Griffith was born in Los Angeles and raised in the Jordan Downs public housing complex. During the late 1980s she became a popular figure in international track and field due to her record-setting performances and flashy personal style. She was the wife of triple jumper Al Joyner and the sister-in-law of heptathlete and long jumper Jackie Joyner-Kersee.
Griffith finished fourth in the 200 m at the inaugural World Championship in 1983. The following year she gained much more attention, though mostly because of her extremely long and colorful fingernails rather than her silver medal in the Los Angeles Olympics 200 m. In 1985, she won the final of the Grand Prix with 11.00 seconds. After these Olympics she spent less time running, and married the 1984 Olympic triple jump champion Al Joyner in 1987.
