Social contact theories present strategies to regulate intergroup relations. These theories started with social contact hypothesis proposed by Allport (1954) and continued with extended contact and imagined contact theories to provide appropriate contact solutions for different contexts. The aim of the current paper is to prepare a source in Turkish by reviewing articles related with intergroup contact theory which is one of the oldest theories in psychology literature, and extended contact and imagined contact theories which were proposed based on intergroup contact theory. There are three parts in the paper and each part explains one of the social contact theories. The first part includes historical progress in intergroup contact theory and findings of studies related with impact of and mechanisms in intergroup contact theory. In this part, there are two additional titles. These titles contain proposals and related findings in social contact hypothesis of Allport (1954) and in intergroup contact theory of Pettigrew (1998). In the second and third parts, findings and hypotheses in extended contact theory and imagined contact theories were demonstrated respectively.
