Miguel Ángel Ruiz Macías (born August 27, 1952), better known as Don Miguel Ruiz, is a Mexican author of Toltec spiritualist and neoshamanistic texts.

His work is best-received among members of the New Thought movement that focuses on ancient teachings as a means to achieve spiritual enlightenment. Ruiz is listed as one of the Watkins 100 Most Spiritually Influential Living People in 2018. Some have associated Ruiz's work with Carlos Castaneda, author of The Teachings of Don Juan.

Don Miguel Ruiz was born in rural Mexico, the youngest of 13 children. He attended medical school, and became a surgeon. For several years he practiced medicine with his brothers.

A near-fatal car accident changed the direction of his life. He promptly returned to his mother to acquire greater moral understanding. He then apprenticed himself to a shaman, and eventually moved to the United States.
