This article proposes a theoretical-methodological reflection on the forms of psychosocial intervention in communities and the contributions that Freud-Lacanian psychoanalyzes can offer to this field. Therefore we will have a bibliographic revision on the topic according to the Community Social Psychology and our professional and academic experience. However our objective is to found a praxiological proposal of intervention in communities and, to do so, we will use some concepts and relevant ideas based in Psychoanalyses, which enable the reflection on the intervention practices of the psychologist, and also of other professionals who work in the social area. In this text, we dialogue with authors like: Jacques Lacan, Slavoj Zizek e Chantal Mouffe.
