An in-group refers to a social group with which an individual identifies, often feeling a sense of loyalty and belonging. This affiliation can enhance feelings of social support and community, as those within the in-group may share common interests, values, beliefs, or identities. The emotional connection to the in-group often leads to a preference for its members over others, which can foster group cohesion and solidarity.

The concept is integral in social psychology as it relates to identity formation and group dynamics, particularly how people perceive themselves in relation to others. Identifying with an in-group can influence behavior, attitudes, and interactions with out-groups—groups that an individual does not belong to. Understanding this concept is crucial in addressing social behaviors, biases, and intergroup relations within various contexts, including cultural, political, and economic spheres.
