Arcangues (pronounced ar-KONG) (foaled March 12, 1988–October 2006) was a French Thoroughbred racehorse and sire. He won the Group 1 Prix d'Ispahan, Prix du Prince d'Orange, Prix Eugène Adam and John Henry Handicap, but is most famous for winning the 1993 Breeders' Cup Classic as a tremendous longshot, a victory that has been called one of the biggest upsets in horse racing history.
