Sun Princess (1980–2001) was an Irish-bred, British-trained Thoroughbred racehorse and broodmare. In a career which lasted from September 1982 until October 1984, she ran ten times and won three races. She recorded all her successes at Group One level when a three-year-old in 1983: the Classic Epsom Oaks by a record margin of twelve lengths; the Yorkshire Oaks against other fillies; the St Leger against colts. In the same season she was placed in Europe's two most prestigious all-aged races, finishing third in the King George VI and Queen Elizabeth Stakes and second in the Prix de l'Arc de Triomphe. Sun Princess raced without winning in 1984 before she was retired to stud, where she became the dam of several winners including the Dewhurst Stakes winner Prince of Dance.
