The Leopard Society also called Anyoto Aniota was a West African secret society active in the early- to mid-20th century that practiced cannibalism. They were centred in Sierra Leone, Liberia, Côte d'Ivoire, and Nigeria.
Members would dress in leopard skins, waylaying travelers with sharp claw-like weapons in the form of leopards' claws and teeth. The victims' flesh would be cut from their bodies and distributed to members of the secret society. According to their beliefs, the ritual cannibalism would strengthen both members of the secret society as well as their entire tribe.
Encounters with what is believed to be a survival of The Leopard Society into the post-colonial era are described by Donald MacIntosh.
