Coretta (foaled February 11, 1994 in Ireland) is a Thoroughbred racemare who competed in the United States. She was bred and raced by Gerald W. Leigh, proprietor of England's Eydon Hall Stud. Leigh owned and bred her dam, Free At Last, who was a daughter of the 1978 Epsom and Irish Derby winner, Shirley Heights. A philanthropist with a strong social conscience who was a member of the Council of Management for the Animal Health Trust, Leigh named Free At Last for those words contained in Martin Luther King Jr.'s 1963 speech, "I Have a Dream". Leigh named Free At Last's first foal, Coretta, for King's widow, Coretta Scott King. Leigh later gave another of Free At Last's foals the name of the African American civil rights activist, Rosa Parks.
