Iroquois (1878–1899), was the first American-bred Thoroughbred race horse to win the prestigious Epsom Derby at Epsom Downs Racecourse, Epsom, Surrey, England. He then went on to win the St. Leger Stakes at Doncaster Racecourse.

Sired by the notable stallion Leamington, he was bred in Pennsylvania by the wealthy stockman, Aristides Welch (the man the winner of the first Kentucky Derby was named for Aristides) and foaled on his Erdenheim Stud farm. His dam was the mare Maggie B. B. by Australian. Aside from Iroquois, she foaled Harold, a full brother to Iroquois, who won the 1879 Preakness Stakes, and Panique, winner of the 1884 Belmont Stakes. Her sire, Australian (who founded the Fair Play sire line), was by West Australian, the first winner of the British Triple Crown.

Another millionaire, Pierre Lorillard IV of the tobacco and snuff family fame, loved the progeny of Leamington so much that in 1879 he bought every Leamington yearling the breeder Aristides Welch had on offer. One of the yearlings he brought home to his Rancocas Stable in Jobstown, New Jersey was Iroquois.
