Dominique Arnold (born September 14, 1973, in Compton, California) is an American hurdling athlete. He is tied for being the seventh fastest all-time 110 m hurdler, with a time of 12.90 s (+1.1 m/s), which was the American record from 2006 till 2010. Arnold set that mark in Lausanne, where he beat the current world record but lost to Liu Xiang.[1] His performance is still the fastest losing time ever ran for the event.
