Relko (1960-Not found) was a French Thoroughbred racehorse who won the 1963 Epsom Derby.  A grandson of Tantieme, he was owned by French hotelier, François Dupré and bred at his stud farm in Pont-d'Ouilly in the Basse-Normandie region.
After winning a number of important races in France  and in England, Relko was retired in September of 1964 after a fetlock injury.  In 1965, he was sent to stand at stud in England. Although he was a top-class sire of middle-and-long distance horses, he had little success as a sire of sires. Of his daughters, My Sierra Leone produced the Champion filly Royal Heroine who won the inaugural running of the Breeders' Cup Mile in North American record time.
