Twilight Alley (1959 – September 1976) was a British Thoroughbred racehorse and sire. A series of physical problems restricted him to four races a track career which lasted from July 1962 to July 1963. On his third racecourse appearance he defeated a strong field to win Britain's most important long-distance race, the Ascot Gold Cup. He broke down injured on his only subsequent appearance and was retired to stud where he had some success as a sire of steeplechasers.
