Festoon (1951–1973) was a British Thoroughbred racehorse and boodmare, best known for winning the 1000 Guineas in 1954 and setting a world record when being sold at auction later that year. In a racing career which lasted from autumn 1953 to July 1954 the filly ran seven times and won three races. After winning her only race as a two-year-old, Festoon won the Classic 1000 Guineas over one mile at Newmarket Racecourse the following spring. She failed to stay the distance in the Epsom Oaks but returned to one mile to win the Coronation Stakes at Royal Ascot and finish third against colts in the Sussex Stakes at Goodwood. She was then retired to stud where she produced several winners.
