Parth (foaled 1920 in Ireland) was a Thoroughbred racehorse best known for winning the 1923 Prix de l'Arc de Triomphe. He was sired by Polymelus, the five-time Leading sire in Great Britain & Ireland. His dam was Willia, a daughter of William The Third whose wins included the 1902 Ascot Gold Cup.
Parth was owned by A. Kingsley Macomber, an American who maintained a sizeable racing operation in Europe and who had won the 1918 Preakness Stakes with War Cloud. Trained in England by James H. Crawford, in 1923 Parth finished third behind winner Papyrus in the Epsom Derby and was fourth in the St. Leger Stakes to winner, Tranquil.
Kingsley Macomber purchased Haras du Quesnay breeding farm in Lower Normandy from William Kissam Vanderbilt and for the 1925 breeding season Parth was retired to stand at stud. As a sire, he met with limited success but did produce Davout, a winner of the 1936 Poule d'Essai des Poulains.
