Jean (or Joanny) Bricaud (February 11, 1881, Neuville-sur-Ain, Ain – February 24, 1934), also known as Tau Jean II, was a French student of the occult and esoteric matters. Bricaud was heavily involved in the French neo-Gnostic movement. He was consecrated a Gnostic bishop on July 21, 1913 by bishop Louis-Marie-François Giraud. He was the Patriarch of the l'Église Gnostique Universelle (French for "Universal Gnostic Church") and a central figure in the various lines of the apostolic succession of subsequent Gnostic Churches, as well as a spiritual heir of Jules Doinel (Valentinus II). From 1916 he was head of the L'Ordre Martiniste. He was a friend of the occultists Papus and August Vandekerkhove.
