In Algonquian folklore, the wendigo (or windigo) is a cannibal monster or evil spirit native to the northern forests of the Atlantic Coast and Great Lakes Region of both the United States and Canada/ Manitoba. The wendigo may appear as a monster with some characteristics of a human, or as a spirit who has possessed a human being and made them become monstrous. It is historically associated with cannibalism, murder, insatiable greed, and the cultural taboos against such behaviours.The legend lends its name to the disputed modern medical term Wendigo Psychosis, which is considered by psychiatrists to be a form of culture-bound syndrome with symptoms such as an intense craving for human flesh and a fear of becoming a cannibal. In some Indigenous communities, environmental destruction and insatiable greed are also seen as a manifestation of Wendigo Psychosis.
