Marienbard (foaled 1997) was an Irish Thoroughbred racehorse bred by Saif Ali and raced by Godolphin Racing. Out of the mare Marienbad, he was sired by the French Champion Three-Year-Old Colt, Caerleon, a son of the 1971 British Triple Crown champion, Nijinsky.
Trained by Saeed bin Suroor, Marienbard was late to develop. In 2000 the colt won an English Listed race, the July Trophy Stakes at Haydock Park Racecourse then in 2001 captured his first important race, the Group 2 Yorkshire Cup plus he finished third to winner Vinnie Roe in the Group I Irish St. Leger. The following year, the then five-year-old horse blossomed into a European standout, winning four of six starts including three consecutive Group 1 races. In Germany he won the Grosser Preis von Baden and the Deutschland-Preis then capped off his racing career with a three-quarter length victory over Sulamani and High Chaparral in France's most prestigious race, the Prix de l'Arc de Triomphe.
Following his Arc win in October 2002, Marienbard was retired to stud duty and was sent to stand at East Stud on the island of Hokkaidō in Japan.
