Wicca (pronounced ) is a neo-pagan, nature-based religion. It was popularised in 1954 by Gerald Gardner, a retired British civil servant, who at the time called it a "Witch cult" and "Witchcraft", and its adherents "the Wica".

Wiccans, as followers of Wicca are now commonly known, typically worship a Goddess (traditionally the Triple Goddess) and a God (traditionally the Horned God), who are sometimes represented as being a part of a greater pantheistic Godhead, and as manifesting themselves as various polytheistic deities. Other characteristics of Wicca include the ritual use of magic, a basic code of morality, and the celebration of eight seasonally based festivals.
