Stephan A. Hoeller (November 27, 1931 – May 3, 2026) was an American author, lecturer and neo-Gnostic bishop.
A lecturer and writer of books and articles about Gnosticism and Jungian psychology, Hoeller was also Regionary Bishop of Ecclesia Gnostica.
Hoeller was ordained to the priesthood in the American Catholic Church by Bishop Lowell P. Wadle in 1958, and consecrated bishop by Richard Duc de Palatine on April 9, 1967. After the death of Palatine, Hoeller changed Palatine's church's name — the Pre-Nicene Gnostic Catholic Church — to Ecclesia Gnostica, and has since held the title of Regionary Bishop.
Hoeller lectured in Australia, New Zealand, the United Kingdom, Sweden, Norway, Iceland, Hungary, Germany, and the United States. He was a member of the lecturing faculty of the late Manly P. Hall's Philosophical Research Society, and a speaker for the Theosophical Society in America. His articles were published in Gnosis and Quest Magazine.
