Gem Twist (June 12, 1979 – November 18, 2006) was a world champion American Thoroughbred show jumping horse registered under the name Icey Twist. Bred by equestrian Frank Chapot, Gem Twist had an incredible career at the Grand Prix level. The gelding is the only horse to have won the "American Grand Prix Association Horse of the Year" title three times, and is regarded as one of the best show-jumpers in history. Two genetic clones of Gem Twist were subsequently foaled after Gem's 2006 death: the first named Gemini, and later a second named Murka's Gem.
