Sceptre (1899–1926) was a British-bred and British-trained Thoroughbred racemare whose career ran from 1901 to 1904. In 1902, she became the only racehorse to win four British Classic Races outright.

The British Classics are five long-standing Group 1 horse races run during the traditional flat racing season. They are restricted to three-year-old horses and traditionally represent the pinnacle of achievement for racehorses against their own age group. As such, victory in any classic marks a horse as amongst the very best of a generation. Victory in two or even three of the series marks a horse as truly exceptional.
