Tolmi (foaled 23 March 1978) was a British Thoroughbred racehorse and broodmare. She won both her races in 1980, including the Princess Margaret Stakes before her season was curtailed by illness and injury, and was rated the equal-best two-year-old filly in Europe. In the following year she was narrowly beaten in the Classic 1000 Guineas before winning the Coronation Stakes at Royal Ascot.
