Salsabil (18 January 1987 – October 1996) was an Irish-bred, British-trained Thoroughbred racehorse and broodmare. In a racing career which lasted from September 1989 to October 1990 she ran nine times and won seven races. Salsabil was one of the leading two-year-old fillies in Europe in 1989, winning two races including the Group One Prix Marcel Boussac at the Longchamp. After winning the Fred Darling Stakes on her three-year-old debut, Salsabil won both of Britain's Classic races for fillies: the 1000 Guineas over one mile at Newmarket and the Oaks over one and a half miles at Epsom. She was then raced against colts and became the first filly for ninety years to win the Irish Derby at the Curragh. In autumn, Salsabil added a victory in the Prix Vermeille at Longchamp but finished unplaced when favourite for the Prix de l'Arc de Triomphe in October. Salsabil was then retired to stud where she had success as a broodmare before dying of cancer in 1996.
