The Power of Myth is a book based on the 1988 PBS documentary Joseph Campbell and the Power of Myth. The documentary was originally broadcast as six one-hour conversations between mythologist Joseph Campbell (1904–1987) and journalist Bill Moyers. It remains one of the most popular series in the history of American public television.

Joseph John Campbell was an American writer. He was a professor of literature at Sarah Lawrence College who worked in comparative mythology and comparative religion. His work covers many aspects of the human experience. Campbell's best-known work is his book The Hero with a Thousand Faces (1949), in which he discusses his theory of the journey of the archetypal hero shared by world mythologies, termed the monomyth.
