Regina Jacobs (born August 28, 1963 in Los Angeles) is an American former middle-distance runner from Los Angeles. She had an extended career that included two IAAF World Championships in Athletics silver medals and an indoor world championship at the age of 39. Three months later, her career ended after winning what would have been a fifth straight National Championship in the 1500 meters when she was disqualified and banned for doping related to the BALCO scandal.
After graduating from Stanford University, Jacobs represented the US in three consecutive Summer Olympics, starting in 1988 in Seoul, South Korea.
Jacobs took second place in the 1500 m race at the 6th World Championships in Athletics in Athens (4:04.63) in 1997, and again won the silver medal in the 1500 m at the World Championships in Sevilla in 1999 (4:00.35). In her years of running she won 25 national titles. On February 1, 2003, at age 39 Jacobs set a world record in the indoor 1500 m with a time of 3:59.98, becoming the first woman to break 4 minutes in the event. Jacobs remains the only American woman to run under 4 minutes in the indoor 1500 meters and stands as the USATF American Indoor record holder in 2015.
In her final years of competition, she was coached by her husband, Tom Craig.
In 2003, she retired after she tested positive for BALCO's 'designer' steroid THG and was suspended from competing in track & field for four years by the United States Anti-Doping Agency.
Following her ban and subsequent retirement, Jacobs became a real estate agent in the Oakland, California, area. She earned an MBA from the University of California, Berkeley. She currently works for The Grubb Co. Realtors, with her husband on her team.
