Kimberlyn Duncan (born August 2, 1991) is an American track and field athlete, specializing in the sprints. She was the 2013 American champion at 200 metres, having defeated Olympic champion Allyson Felix with a strong stretch run. Her time of 21.80 seconds from that race at the 2013 USA Outdoor Track and Field Championships would have ranked her as the 14th fastest female of all time, had it not been wind aided. She is currently 42nd on that list, from a qualifying heat at the NCAA Championships on the same Drake Stadium track a year earlier.
Duncan was a standout athlete at Cypress Springs High School near her hometown in Katy, Texas, graduating in 2009. She ran track collegiately at Louisiana State University , where she became the first woman to win the NCAA Championships 200 meters back to back, both indoors and outdoors.
At the 2012 NACAC Under-23 Championships in Athletics she again won the 200 meters in record time and anchored the victorious USA 4x100 metres relay team. A few weeks later, she anchored the USA "Blue" team to the meet record at Herculis.
