Dorothy Eugénie Brett (10 November 1883 - 27 August 1977) was a British painter, remembered as much for her social life as for her art. Born into an aristocratic British family, she lived a sheltered early life. During her student years at the Slade School of Art, she associated with Dora Carrington, Barbara Hiles and the Bloomsbury group. Among the people she met was novelist D. H. Lawrence, and it was at his invitation that she moved to Taos, New Mexico in 1924. She remained there for the rest of her life, becoming an American citizen in 1938.
Her work can be found in the Smithsonian American Art Museum in Washington D.C., in the Millicent Rogers Museum and the Harwood Museum of Art, both in Taos. Also at the New Mexico Museum of Art, Santa Fe, the Roswell Museum and Art Center, Roswell, New Mexico and in many private collections.
