Cloonagh (1970 – 1975) was an Irish-bred, British-trained Thoroughbred racehorse and broodmare. After winning one minor race as a two-year-old she showed great improvement in the following spring when she took the Pretty Polly Stakes in England before recording her biggest win in the Irish 1000 Guineas. She was well beaten in her last two races and was retired at the end of the season. She produced one foal before dying in 1975 at the age of five.
