Nun Nicer (1895–1915) was a British Thoroughbred racehorse and broodmare. As a two-year-old in 1897 she ran consistently, winning three of her nine races including the Manchester Summer Foal Plate and Hopeful Stakes as well as being placed on four occasions. In the following year she won the 1000 Guineas, Triennial Stakes, September Stakes and Palatine Plate and finished second in the Epsom Oaks and Coronation Stakes. As a four-year-old she ran second in the Stewards' Cup and won the Preis von Donausschingen in Germany. She made no impact as a broodmare.
