Your Host (1947–1961) was an American Thoroughbred racehorse. Foaled in California, he was by the imported British stallion Alibhai out of the Irish mare Boudoir by the French stallion Mahmoud. Bred in the stables of Louis B. Mayer (head of Metro Goldwyn Mayer), Your Host was owned by Mayer's son-in-law (film producer William Goetz) and trained by Harry L. Daniels. Despite illness and injury he had a successful racing career, and went on to sire the great gelding Kelso.
