Chief's Crown (April 7, 1982 – April 29, 1997) was an American-bred Thoroughbred race horse who won the 1984 Breeders' Cup Juvenile and was voted the Eclipse Award for Outstanding Two-Year-Old Male Horse. He later became a successful sire.

Chief's Crown was a son of leading sire Danzig and Six Crowns, who was by Secretariat and out of the 1974 U.S. Filly Triple Crown winner Chris Evert.^[2] He was owned by the Star Crown Stable of the family of the late Carl Rosen, who had owned Chris Evert. They syndicated a half-interest in Chief's Crown to Three Chimneys Farm prior to his Breeders' Cup victory plus another quarter-interest to Claiborne Farm on his retirement.

Chief's Crown is the only horse in history to lose all three U.S. Triple Crown races while being the betting favorite for each race.^[3] He finished 3rd to Spend A Buck in the Kentucky Derby, then in the Preakness Stakes set a record for the fastest first mile but finished a head behind Tank's Prospect. In the Belmont Stakes, Chief's Crown finished 3rd to Creme Fraiche. He came back later that year to win the Travers Stakes and the Marlboro Cup Invitational Handicap.

At the end of the 1985 racing season, Chief's Crown was retired to stand at stud at Three Chimneys Farm in Kentucky, where he died in 1997. He served two seasons in Australia in the 1990s, where he sired 93 foals, including 11 stakes winners with 20 stakes wins.^[4]

Among his progeny were the Canadian Horse Racing Hall of Fame colt, Chief Bearhart and the 1994 Epsom Derby winner Erhaab. He is also the grandsire of Sinndar, who in 2000 became the only horse to ever win The Derby, Irish Derby Stakes, and Prix de l'Arc de Triomphe in the same year.
