War Admiral (1934-1959), was a thoroughbred racing horse, the son of the great Man O' War.

War Admiral won 21 of his 26 starts, including the coveted Triple Crown in 1937. He raced in the Eastern United States and is linked forever to Seabiscuit, who was a pre-eminent horse based primarily in the Western U.S. Their famous match race in 1938 is considered by some to be the best in thoroughbred horse-racing in American history.
