A new religious movement (NRM) is a faith-based community, or ethical, spiritual, or philosophical group of recent origin. NRMs may be novel in origin or they may be part of a wider religion, such as Christianity, in which case they will be distinct from pre-existing denominations. Scholars studying the sociology of religion have almost unanimously adopted this term as a neutral alternative to the word "cult". They continue to try to reach agreement on definitions and boundaries.

An NRM may be one of a wide range of movements ranging from those with loose affiliations based on novel approaches to spirituality or religion to communitarian enterprises that demand a considerable amount of group conformity and a social identity that separates their adherents from mainstream society. Use of the term is not universally accepted among the groups to which it is applied. NRMs do not necessarily share a set of particular attributes, but have been "assigned to the fringe of the dominant religious culture", and "exist in a relatively contested space within society as a whole".
