Lashinda Demus (born March 10, 1983, in Inglewood, California) is a retired American hurdler who specialized in the 400 meter hurdles, an event in which she was the 2011 world champion and 2012 Olympic gold medalist, becoming the first woman from the United States to win the Olympic 400 m hurdles title.

Demus' personal best time over 400 m hurdles is 52.47 seconds, set in Daegu, South Korea on September 1, 2011, making her as of December 2022 the seventh-fastest woman in history in the event.

However, Demus got her revenge at the 2011 World Championships in Athletics in Daegu, South Korea, when she won the gold medal in 52.47 seconds, a new American Record and the third fastest time in history.

Heavy favorite Kaliese Spencer who had set the fastest time in 2011, could only finish fourth behind Demus, Walker and 2010 European Champion and 2004 Olympic 400 m bronze medalist Natalya Antyukh.
