Princess Dorrie (1911 – 1927) was a British Thoroughbred racehorse and broodmare. As a two-year-old in 1913 she failed to win a race but was very consistent, finishing placed in seven of her eight starts. In the following year she was probably the best three-year-old filly in England, winning both the 1000 Guineas and the Epsom Oaks. She was retired at the end of the 1914 season and had modest success as a broodmare.
