Edith Mahier (1892 – 1967) was an American artist and art instructor who was instrumental in helping develop the talent of the Kiowa Six during their studies at the University of Oklahoma.

In 1941, she won the commission to complete the post office mural for the U.S. Treasury Department's Section of Fine Arts at the Watonga, Oklahoma, facility.

In her later career at OU she created a division of the arts department dedicated to fashion and even designed motifs for a clothing line developed by Neiman Marcus.

The following term, Asah, Hokeah and their fellow artists, Stephen Mopope and Monroe Tsatoke[16] were admitted to a special program at the university and Mahier became their teacher, critic and mentor.

Since the Kiowa artists did not meet the entrance requirements and Jacobson was convinced their natural talent needed only coaching,[17] Mahier allowed them to use her office as a studio and gave them a balance of criticism and encouragement.

[16] She was forbidden to give instruction on abstract techniques, perspective, or shading,[18] but guided them with discussions about anatomy, including the question of whether Indians had six fingers, and comments about rhythm and design elements.

[21] Exhibitions of their work at the Denver Art Museum and on a tour in Czechoslovakia soon earned the group the name of the Kiowa Six, critical acclaim and enduring fame.

[32] Mahier died December 2, 1967, in Natchez, Mississippi, and was buried at Roselawn Memorial Park and Mausoleum, in Baton Rouge, Louisiana.
