Prohibit (foaled 14 February 2005) is a retired British Thoroughbred racehorse who excelled over sprint distances, producing most of his best performances over five furlongs. In his first three seasons he was trained by John Gosden and showed useful form, winning three minor races but appearing to be some way short of top class. After being sold and transferred to the stable of Robert Cowell he showed improved form, winning the sprint race at the 2010 Shergar Cup and winning a strongly contested edition of the Scarbrough Stakes. He reached his peak as a six-year-old in 2011 when he won a handicap race in Dubai, the Group One King's Stand Stakes at Royal Ascot and the Prix du Petit Couvert in France as well as running prominently in several other major sprints including the Prix de Saint-Ge
