Alysheba (March 3, 1984 – March 27, 2009) was an American Thoroughbred racehorse that won two legs of the Triple Crown in 1987. A successful sire, he produced 11 stakes winners.
A bay colt, Alysheba was sired by Alydar out of the mare Bel Sheba, by Lt. Stevens. He was bred by Preston Madden at Hamburg Place Farm in Lexington, Kentucky, and was sold as a yearling to Dorothy and Pam Scharbauer for $500,000.
Trained by Jack Van Berg, Alysheba had a modest two-year-old season in 1986, and won only a maiden race. He finished third in the Breeders' Cup Juvenile, and lost the Hollywood Futurity in a photo finish. As a three-year-old, he underperformed in his preparatory races for the Kentucky Derby until it was discovered that he had an entrapped epiglottis. Surgery was successful, and he was entered in the Derby despite having only a maiden victory.
