Mary Morez (January 16, 1946 – September 25, 2004) was a Navajo painter.
Born near Tuba City, Arizona, Morez was stricken with both polio and rheumatic fever as a girl, and underwent numerous operations as a result before being adopted by Lawrence and Mary Keim.
She first studied at the Phoenix Indian School before receiving a bachelor's degree from the University of Arizona and received a scholarship to study fashion illustration at the Ray Vogue Art School in Chicago.
In 1969 she chose to devote her work to full-time painting instead of commercial art.
Allan Houser and Oscar Howe served as her mentors early in life.
Her work combined traditional Navajo elements with a more contemporary, abstract style.
Besides painting Morez also worked as a textile artist.
For much of her career she lived in Phoenix, Arizona.
Morez is represented in the collection of the Wheelwright Museum of the American Indian.
