The Leopard Society, leopard men, or Anyoto was a secret society that operated in West Africa approximately between 1890 and 1935. It was believed that members of the society could transform into leopards through the use of witchcraft. The earliest reference to the society in western literature can be found in George Banbury's "Sierra Leone: or the white man's grave" (1888). In western culture, depictions of the society have been widely used to portray Africans as barbaric and uncivilized.

A secret society is an organization about which the activities, events, inner functioning, or membership are concealed. The society may or may not attempt to conceal its existence. The term usually excludes covert groups, such as intelligence agencies or guerrilla warfare insurgencies, that hide their activities and memberships but maintain a public presence.
