Sheriff's Star (27 April 1985 – after 1995) was a British Thoroughbred racehorse and sire. As a two-year-old he won his first two races before establishing himself as one of the best British colts of his generation with a close second in the William Hill Futurity. In the following year he won the King Edward VII Stakes and Great Voltigeur Stakes, but was well-beaten in both the Derby and the St Leger. He reached his peak as a four-year-old in 1989 when he recorded Group One successes in both the Coronation Cup and Grand Prix de Saint-Cloud. He later stood as a breeding stallion in Japan where he had some success as a sire of winners.

Sheriff's Star was a "tall, leggy, sparely-made" grey horse bred by his owner Lavina, Duchess of Norfolk. He was probably the best European horse sired by Posse, a Kentucky-bred stallion who won the St. James's Palace Stakes and Sussex Stakes in 1980. Sheriff's Star's dam, Castle Moon, produced seven other winners including the St Leger Stakes winner Moon Madness. Castle Moon was a half-sister of the Ascot Gold Cup winner Ragstone and, as a descendant of the mare Herringbone was closely related to many good winners including Kings Lake, Michelozzo and Celtic Swing. The Duchess sent her colt into training with her daughter Lady Herries at Angmering Park in West Sussex. He was ridden in most of his races by Tony Ives.
