The Horned God is one of the two primary deities found in some neopagan, especially Wiccan, religions. He represents the male part of the religion's duotheistic theological system, the other part being the female Triple Goddess or other Mother Goddess. In common Wiccan belief, he is associated with nature, wilderness, sexuality, hunting and the life cycle. Whilst depictions of the deity vary, he is always shown with either horns or antlers upon his head, often depicted as being theriocephalic (having a beast's head), in this way emphasizing "the union of the divine and the animal", the latter of which includes humanity.
The term Horned God itself predates Wicca, and is an early 20th-century syncretic term for a horned or antlered anthropomorphic god with pseudohistorical origins. According to Margaret Murray's 1921 The Witch-Cult in Western Europe, the Horned God was the deity worshipped by a pan-European witchcraft-based cult, and was demonized into the form of the devil by the Mediaeval Church.
The Horned God has been explored within several psychological theories, and has become a recurrent theme in fantasy literature.
