This article is about clubs referring to a particular organization of people. For other article subjects named club see club (disambiguation).

A club is generally an association of people united by a common interest or goal, as opposed to any natural ties of kinship. Such clubs occur in all ancient states of which we have detailed knowledge. Once people started living together in larger groups, there was need for men with a common interest to be able to associate despite having no ties of kinship.

The term club now has broader implications. The Service club, for example, exists for voluntary or charitable activities; there are clubs devoted to all sorts of hobbies, sports, and games, political and religious clubs, Social Activities Clubs that appeal to a variety of interests, and so forth. See for example BSAC (a big British scuba diving club). The term Club can also refer to a nightclub or discothèque.
