Mapuche religion is the traditional Native American religion of the Mapuche people. It is practiced primarily in south-central Chile and southwest Argentina. The tradition has no formal leadership or organizational structure and displays much internal variation.
Mapuche theology incorporates a range of deities and spirits. One of the most prominent deities is Ngünechen, sometimes equated with the Christian God. Communal prayer ceremonies are termed ngillatun and involve the provision of offerings and animal sacrifice. Ritual specialists, called machi, are responsible for contacting the spirits and overseeing healing rituals. These myths tell of the creation of the world and the various deities and spirits that reside in it.
In 1883 the Chilean military defeated the Mapuche and began to restrict them to reservations. Chilean efforts were then made to convert the Mapuche to Roman Catholicism. From the 1990s, Mapuche religion underwent a revitalisation, with greater visibility and efforts to use it to encourage tourism.
