In German, Indian reservations (also: Indianer-Reservationen) are concretely defined areas with separate legal status, which were assigned to indigenous ethnic groups of America ("Indians") by various states. Their establishment occurred as a result of the colonization of the Americas, predominantly in the 19th century. In some cases (particularly in the remaining wilderness areas of Canada and Amazonia), such reservations are located on former tribal territory, but in most cases they constitute only a small to very small portion of that territory. The geographic location and extent was determined without any co-determination of the affected people, in contrast to autonomous regions of indigenous peoples (such as the Indian land areas in Canada's Yukon Territory or the autonomous regions of Nicaragua).

Indian reservations exist under the following designations in some states of North, Central, and South America:

  • Canada: Indian reserve or French réserves indiennes
  • USA, Belize: English Indian reservation
  • Costa Rica, Nicaragua, Ecuador, Guyana: Spanish Territorios Indígenas
  • Dominica: English Carib Territory
  • Panama: Spanish Comarcas indígenas
  • Venezuela: Spanish Tierras con títulos colectivos
  • Colombia: Spanish Resguardos indígenas and Reservas indígenas
  • Peru: Spanish Reservas comunales and Spanish Reservas territorial para pueblos indígenas en aislamiento
  • Brazil: Portuguese Terras indígenas
  • Bolivia: Spanish Tierra Comunitarias de Origen or Territorios indígenas originario campesino
  • Argentina: Spanish Posesión y propiedad comunitarias de las tierras de argentina

Most of the reservations in North America, and the largest in terms of area, are located in the western part of the USA - concentrated in the mountain states of Arizona, Utah and Montana, as well as in South Dakota. In Canada, First Nations reserves are scattered across more than 3000 small and micro units.

The largest reserves in the Americas are in Brazil. In Colombia and Brazil, the larger reserves are located in the border areas with neighbouring countries and in the drainage area of the Amazon.
