Florence Delorez Griffith Joyner (born Florence Delorez Griffith; December 21, 1959 – September 21, 1998), also known as Flo-Jo, was an American track and field athlete. She set world records in 1988 for the 100 m and 200 m. During the late 1980s she became a popular figure due to both her record-setting athleticism and eclectic personal style.

Griffith Joyner was born and raised in California. She was athletic from a young age and began running at track meets as a child. While attending California State University, Northridge (CSUN) and University of California, Los Angeles (UCLA), she continued to compete in track and field. While still in college, she qualified for the 100 m 1980 Olympics, although she did not actually compete due to the U.S. boycott. She made her Olympic debut four years later, winning a silver medal in the 200 meter distance at the 1984 Olympics held in Los Angeles. At the 1988 U.S. Olympic trials, Griffith set a new world record in the 100 meter sprint. She went on to win three gold medals at the 1988 Olympics.

In February 1989, Griffith Joyner abruptly retired from athletics. She remained a pop culture figure through endorsement deals, acting, and designing. She died in her sleep as the result of an epileptic seizure in 1998 at the age of 38. She is buried at the El Toro Memorial Park in Lake Forest.
