Atmah (1908 – after 1915) was a British Thoroughbred racehorse and broodmare. She failed to win as a two-year-old but showed considerable promise on her final start when she ran third in the Dewhurst Stakes. In the following year she contested four of the five British Classic Races, recording her biggest success when taking the 1000 Guineas. She made no impact as a broodmare.
