The Transcendental Painting Group (TPG) was an artist collective, established in 1938 in Taos, New Mexico. The group's goal was to provide an alternative to the prevailing currents of social realism and regionalism that dominated art in the 1930s United States. Under the leadership of Raymond Jonson and Emil Bisttram, the artist group consisted of Agnes Pelton, Lawren Harris, Florence Miller Pierce, Horace Pierce, Robert Gribbroek, William Lumpkins, and Dane Rudhyar. Most of the members lived and worked in New Mexico, with the exception of Agnes Pelton, who was active in Southern California.
