Plack (1921–1940) was a British Thoroughbred racehorse and broodmare. As a juvenile in 1923 when she won three races and finished second to Diophon in the Middle Park Stakes. In the following year she recorded her biggest victory when taking a very strong renewal of the 1000 Guineas and then finished second in the Epsom Oaks. Later that year she added wins in the Newmarket Oaks and the Jockey Club Cup. She failed to win in 1925 but was placed in the Coronation Cup, Hardwicke Stakes, Doncaster Cup and Jockey Club Cup. Despite producing few foals she had some influence as a broodmare.
