Doris Ulmann (1884-August 28, 1934) was an American photographer, best known for her photographs of the people of Appalachia made between 1928 and 1934.
Ulmann grew up in New York City, where she graduated from the Ethical Culture Fieldston School. Ulmann also graduated from the Clarence H. White School of Modern Photography.
The folk singer and composer John Jacob Niles took four trips to Appalachia as an assistant to Ulmann, during which time he collected and documented many traditional songs.
Much of Ulmann's work is under the control of the Doris Ulmann foundation, at Berea College in Kentucky. Her photographs are also part of many collections including the Smithsonian and the J. Paul Getty Museum.
In August of 1934 Ulmann was working near Ashville, North Carolina, when she fell ill. She died later that month in New York City.
