Born in Lehigh, Choctaw Nation, Indian Territory, her mother, Ida Belle Richards, was a Presbyterian missionary teacher and her father, Dr. Eliphalet Nott Wright, was a Choctaw and a graduate of Union College and Albany Medical College in New York.

She served as the secretary of the Choctaw Committee during the 1920s and in 1934 was a member and secretary of the Choctaw Advisory Committee. In the late 1930s and early 1940s Wright served as a Choctaw delegate to the Intertribal Indian Council. Muriel Wright was educated in Norton, Massachusetts at Wheaton Seminary and returned to Lehigh in 1910. In 1912 Wright completed a teacher education course at East Central Normal School but never received a degree.
