Dr. MORRIS EDWARD OPLER (1907–1996) was an American cultural anthropologist.

Best known for his work on the folklore and cultural history of Apaches, Opler also developed an interest in Asian studies. During his ethnographic work with Japanese internees in a California War Relocation Center, he spoke up for the civil rights of the Japanese Americans, just like he strongly advocated the rights of the Apache peoples.

Two of his major works are An Apache life-way (“one of the most important and innovative studies of southwestern Native Americans”) from 1941 and Apache Odyssey from 1969.
