This paper has, as its main goal, to analyse the presentation and re-presentation of the Mapuche, Peruvian and Bolivian difference in the Chilean press. The media which will be the object of the study selected because of its periodicity and extensive coverage are the tabloid press "La Cuarta" and "Las Ultimas Noticias" which in turn and respectively belong to the consortia which duopolise the informative issue at a national level: Copesa and El Mercurio S.A.P In order to can); out this analysis a methodological matrix has been projected, and which is derived from the proposal by Teun van Dijk, the so called Critical Discourse Analysis (CDA). This will allow the reader to understand the social construction of reality based on the news treatment in and of the possible intercultural-migratory relationships inside (Mapuche) and outside (Peruvian-Bolivian) the country.
