An athame or athamé is a ceremonial blade, generally with a black handle. It is the main ritual implement or magical tool among several used in ceremonial magic traditions, and by other neopagans, witchcraft, as well as satanic traditions. A black-handled knife called an arthame appears in certain versions of the Key of Solomon, a grimoire dating to the Renaissance.

In the neopagan religion of Wicca a range of magical tools are used in ritual practice. Each of these tools has different uses and associations and are commonly used at an altar, inside a magic circle.
