Bitty Girl (1971–1994) was a British Thoroughbred racehorse and broodmare. She was one of the leading fillies of her generation in 1973 when she won her first five races including the Queen Mary Stakes, Molecomb Stakes and Lowther Stakes. In the following year she failed to win but ran prominently in some major sprint races before being sold at the end of the eaon and sent to race in the United Stakes where she won three minor races.
