John Frederick Carden Michell (9 February 1933 – 24 April 2009) was an English author and esotericist who was a prominent figure in the development of the Earth mysteries movement. Over the course of his life he published over forty books on an array of different subjects, being a proponent of the Traditionalist school of esoteric thought. Michell's impact in the Earth mysteries movement was considerable, and through it he also influenced the British Pagan movement. During the 2000s, his ideas also proved an influence on the Radical Traditionalist sector of the New Right.
