Neopaganism is a collective term for new religious movements influenced by or derived from the various historical pagan beliefs of pre-modern Europe, North Africa and the Near East. Although they do share similarities, contemporary Pagan religious movements are diverse, and no single set of beliefs, practices or texts are shared by them all.[3] Most academics studying the phenomenon have treated it as a movement of different religions, whereas a minority instead characterise it as a single religion into which different Pagan faiths fit as denominations. Not all members of faiths or beliefs regarded as Neopagan self-identify as "Pagan".

Adherents rely on pre-Christian, folkloric and ethnographic sources to a variety of degrees; many follow a spirituality which they accept as being entirely modern, while others attempt to reconstruct or revive indigenous, ethnic religions as found in historical and folkloric sources as accurately as possible.[4] Academic research has placed the Pagan movement along a spectrum, with Eclecticism on one end and Polytheistic Reconstructionism on the other. Polytheism, animism and pantheism are common features in Pagan theology. Rituals take place in both public and in private domestic settings.

The Pagan relationship with Christianity is often strained. Contemporary Paganism has sometimes been associated with the New Age movement, with scholars highlighting both similarities and differences. From the 1990s onwards, scholars studying the modern Pagan movement have established the academic field of Pagan studies.
