Neopaganism, also spelled as Neo-Paganism, is

[t]he new paganism – a nature-oriented religious movement whose followers either are nature worshippers or have a very high regard for nature. It includes the reinventing or revival of the old gods and goddesses of pre-Christian polytheistic mythologies, mystery cults, and nature religions, such as Celtic, Greek, Egyptian, Roman, or Sumerian, or the interest in existing tribal religions (e.g. Native American religions), and shamanism, or the making of new religions.

The term is used to distinguish followers of contemporary religions and religious movements rooted in paganism from historical pagans.
