Kings Best (24 January 1997 – 16 April 2019) was an American-bred Thoroughbred racehorse best known for winning the 2000 Guineas Stakes. He was described by his trainer Michael Stoute as the best miler he'd ever trained.
After winning his maiden race at Newmarket he won, from the front, in York's 1999 Acomb Stakes, a Group 3 race for juveniles.
His first start as a three-year-old resulted in a second place to Umitism in the Craven Stakes at Newmarket. Few horses beaten in that race go on to win the 2000 Guineas, so it was a surprise when he claimed the first classic of the season, sprinting past Giant's Causeway from off the pace. Ridden by Kieren Fallon he sprinted to a three-and-a-half length victory.[4]
King's Best true ability was never satisfactorily determined as injury in his next race, the Irish Derby ended his career prematurely.
