Dallas Stewart (born September 15, 1959 in McComb, Mississippi) trains a string of thoroughbred horses in Kentucky from bases at Churchill Downs, Turfway Park, Keeneland Race Course, Fair Grounds Race Course, Arlington Park and Saratoga Race Course. Before venturing out on his own, he spent 12 years working under the tutelage of leading trainer D. Wayne Lukas. There, he oversaw such horses as Lady's Secret, Thunder Gulch, Serena's Song, Timber Country, Tabasco Cat, and many other Grade I winners.
