A society is a group of humans or other organisms of a single species that is delineated by the bounds of cultural identity, social solidarity, functional interdependence, or eusociality. Human societies are characterized by patterns of relationships between individuals that share a distinctive culture or institutions. Like other groups, a society allows its individual members to achieve individual needs or wishes that they could not fulfill separately by themselves, without the existence of the social group. Society, however, may be unique in that it is ontologically independent of, and utterly irreducible to, the qualities of its constituent individuals. As a reality sui generis, or "of its own kind", it is emergently composed of social facts that often hinder rather than help the pursuits of the subjects that form its physical and psychological underpinnings.

More broadly, a society is an economic, social or industrial infrastructure, made up of a varied multitude of individuals. Members of a society may be from different ethnic groups. A society may be a particular ethnic group, such as the Saxons; a nation state, such as Bhutan; a broader cultural group, such as a Western society; or even a social organism such as an ant colony.

The word society may also refer to an organized voluntary association of people for religious, benevolent, cultural, scientific, political, patriotic, or other purposes. Sociology is the study of society and social behavior.
