Stewart Elliott is an American thoroughbred jockey.
Elliott grew up in horse racing; his father was a jockey for many years, his mother rode show horses and was a riding instructor, and his uncle owns a racing stable in Canada. At age seven, his family moved to race in Hong Kong where they remained for six years before going to the United States. Stewart began riding professionally at age 16, mainly at Philadelphia Park Racetrack, a small racetrack in suburban Philadelphia, Pennsylvania. A steady, hard worker, he has been the racetrack's most successful jockey for a number of years and for the past three seasons has been named Pennsylvania's top rider. On May 13, 2003 he reached a prestigious milestone, riding his 3,000th career winner. On January 18, 2009 he won the 4,000th race of his career at Philadelphia Park.
In 2004 was Stewart's big break when on May 1, 2004, Elliott became the first jockey in twenty-five years to win the Kentucky Derby in his first appearance in the race. His horse, Smarty Jones, became the first unbeaten Derby winner since Seattle Slew in 1977. To add to his victory was Elliott's 10% share of the almost $6 million in purse and bonuses that represented the largest payday for any jockey and horse in racing history. Two weeks later, Elliott rode Smarty Jones to a record-breaking win in the second leg of the Triple Crown of Thoroughbred Racing, the Preakness Stakes. In the Belmont Stakes, the third leg, Elliott took Smarty Jones out early in the backstretch. Smarty Jones made a valiant effort, but Birdstone passed him in the end.
