Carotene (foaled 1983 in Ontario) is a Canadian Thoroughbred Hall of Fame racehorse who holds the filly or mare record for winning the most Sovereign Awards. Bred by Kinghaven Farms, she was a daughter of the British sire Great Nephew, who also sired Epsom Derby winners Grundy and Shergar. Carotene's dam was Carrot Top, a mare David Willmot purchased in foal from the Whitney family at the 1982 dispersal sale of their bloodstock in the United Kingdom.
