Children of Artemis (CoA) is an educational and networking organization for the promotion of Wicca based in the United Kingdom. Children of Artemis organizes the world’s largest witch festival, Witchfest, held annually in London, Cardiff, Wales, and Glasgow, Scotland. The CoA was formed in the early 1990s as a ritual group. In 1995 it became a public organization. Since 2000, it has grown rapidly.
CoA publishes a magazine, Witchcraft & Wicca, and holds events in addition to the festival. The CoA assisted the Pagan Federation with its conference in 1998 and 1999. Witchfest was launched in 2002. Until 2003, the CoA had a COVEN-finding service for people interested in joining the Craft, but had to discontinue it because there were not enough covens to accommodate the large number of applicants.
