My Typhoon (foaled 2002 in Ireland) is an American Thoroughbred racehorse whom the NTRA calls "one of the world's best-bred horses."
Bred in Ireland by David Tsui's Sunderland Holdings, she was sired by Giant's Causeway, a son of Storm Cat whose stud fee in 2006 became the highest in the world at $500,000.
At the December 2002 Tattersalls Sale, My Typhoon was sold as a weanling to Live Oak Stud of Ocala, Florida, for a then-record price of US$2.95 million.
At Churchill Downs in 2005, My Typhoon won her first significant race, capturing the Grade II Mrs. Revere Stakes.
In August, she won the GII Ballston Spa Breeders' Cup Handicap and after a third place in the First Lady Stakes at Keeneland Race Course returned to Churchill Downs, where she finished sixth in November's Breeders' Cup Filly & Mare Turf won by Ouija Board.
