: ''This article does not discuss "cult" in its original sense of "religious practice"; for that usage see Cult (religious practice). See Cult (disambiguation) for more meanings of the term "cult"''.
In religion and sociology, a cult is a cohesive group of people (often a relatively small and recently founded religious movement) devoted to beliefs or practices that the surrounding culture or society considers to be far outside the mainstream. Its separate status may come about either due to its novel belief system, because of its idiosyncratic practices or because it opposes the interests of the mainstream culture. Other non-religious groups may also display cult-like characteristics.
In common usage, "cult" has a negative connotation, and is generally applied to a group by its opponents, for a variety of reasons.
Understandably, most, if not all, groups that are called "cults" deny this label. It has been argued that no one yet has been able to define “cult” in a way that enables the term to identify only groups that have been claimed as problematic.
