Apology (1871–1888) was a British Thoroughbred racemare who was the third winner of the Fillies' Triple Crown, winning The Oaks, 1,000 Guineas Stakes and St. Leger Stakes in 1874. Apology was bred and owned by the Reverend John William King, the vicar of Ashby de la Launde, whose ownership of the mare caused a minor scandal in the Church of England after Apology won the St. Leger Stakes. King ultimately had to resign his clerical appointments due to the scandal and died shortly thereafter of a chronic illness. Apology raced until she was five years old, winning the Ascot Gold Cup in 1876. She was retired from racing at the end of 1876 to become a broodmare initially for the widow of John King, and then for Clare Vyner. Apology was euthanised in 1888 after an extended illness.
