Circus Plume (1981–1996) was a British Thoroughbred racehorse and broodmare best known for winning the classic Oaks Stakes in 1984. After winning once from three starts in 1983, Circus Plume improved to become one of the best staying fillies in Europe as a three-year-old, winning the Oaks and the Yorkshire Oaks as well as finishing second in the Irish Oaks and the Prix Vermeille. She failed to show any worthwhile form in 1985 and was retired to stud, where she had some success as a broodmare.
