Interpersonal attraction as a part of social psychology is the study of the attraction between people which leads to the development of platonic or romantic relationships. It is distinct from perceptions such as physical attractiveness, and involves views of what is and what is not considered beautiful or attractive.

Within the study of social psychology, interpersonal attraction is related to how much one likes or dislikes another person. It can be viewed as a force acting between two people that tends to draw them together and to resist their separation. When measuring interpersonal attraction, one must refer to the qualities of the attracted and those of the attractor to achieve predictive accuracy. It is suggested that to determine attraction, both the personalities and the situation must be taken into account.
