This article seeks an ethnographic approximation of inter-ethnic relations in the cities of Patagonia. Taking into account discussions recently generated by Mapuche organisations on the Mapuche presence in urban areas and the specific problem that this represents, the intention here is to address the complex identity of the surrounding areas of cities. This work is based on one of the points I developed in my bachelor thesis that concerned the rearrangement of identities in a peripheral neighbourhood of the city of Bariloche composed of internal migrants from rural areas in the provinces of Rio Negro and Neuquén (mostly of Mapuche origin) and Chilean migrants. In this work, in particular, the process of urban rearrangement of ethnically marked identities in discernible categories such as neighbour. To that end, I draw on the barrial ethnography and analysis of the discurso.An ethnographic approach to interethnic relationships in cities of Patagonia is presented in this article. Taking under consideration voices of mapuche organisations on recent discussions about the complex urban mapuche situation, the aim of this approach is to study identity dynamics in city Peripheral neighbourhoods. This article is based on my thesis of Licenciatura, which explored identity links in a Peripheral neighbourhood of Bariloche city that congregates migrants who have been mainly driven from rural areas, as a rule, mapuche people of Rio Negro and Neuquén, and also from Chile. The intention here is to focus specifically on urban identity identity articulations applying an ethnographic and discourse centred approach.
