Kings Best (24 January 1997 – 16 April 2019) was an American-bred Thoroughbred racehorse best known for winning the 2000 Guineas Stakes.
His progeny included the British Classic winners Russian Rhythm, Henrythenavigator, Virginia Waters and Rule of Law, as well as major winners in Japan (El Condor Pasa), France (Divine Proportions) and the United States (Lemon Drop Kid).
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.
[4] King's Best true ability was never satisfactorily determined as injury in his next race, the Irish Derby ended his career prematurely.
Standing with Darley Stud, Kings Best sired numerous high-profile winners including Creachadoir, Royal Diamond, Allybar and Eishin Flash, but his most famous son is the Michael Stoute-trained Workforce, who won the Derby by seven lengths in 2010, followed by the Prix de l'Arc de Triomphe.
