Saucy Sue (1922– July 1937) was a British Thoroughbred racehorse and broodmare, best known for winning two Classics in 1925. The filly won eight times from ten races in a racing career which lasted from July 1924 until October 1925. She was the top-rated British two-year-old of either sex in 1924, when she was unbeaten in three races. In her first two races the following year she won the 1000 Guineas over one mile at Newmarket and The Oaks over 1+1⁄2 miles at Epsom Downs Racecourse a month later. Saucy Sue took her unbeaten run to seven by winning the Coronation Stakes at Royal Ascot and the Nassau Stakes at Goodwood. She was defeated in her next two races and was retired from racing at the end of the season after a final win in the Atalanta Stakes at Sandown Park.
