Clifford Bias (1910–1987) was a prominent American alleged psychic in the early 20th-century. He claimed that he had been able to communicate with people who had long since died from the age of five. He was ordained into the ministry in 1937. He helped organize the Spiritualist-Episcopal Church and the Universal Spiritualist Association. Bias organized a magical study group known as the Ancient Mystical Order of Seekers (A.M.O.S.) and he wrote and published a series of A.M.O.S. books.
