Miss Disco (1944–1974) was an American Thoroughbred racemare that won important sprint events against colts during her racing career but she secured her place in history when, as a broodmare at Claiborne Farm, she was bred to Nasrullah and produced the very influential National Champion and Hall of Fame sire Bold Ruler.
