List of Religions, Worldviews, and Belief Systems

March 17, 2004 · updated January 10, 2024

This page provides an index to our articles on religions from ancient faiths to new religious movements. It is not comprehensive, of course, and grows regularly. It includes sects and denominations (like Baptists and Zen) along with major religions (like Christianity or Buddhism).

ReligionFacts is very inclusive with what is regarded as a "religion" for purposes of this index and this website. Some of these belief systems may not be "religions" according to traditional definitions (they might better be called "philosophies" or "movements"), and some are even anti-religion. The grounds for a group's inclusion is simply that it offers an explanation of ultimate reality or the purpose of life and has attracted a significant number of followers.

See our Big Religion Chart to compare the basics of over 40 of these faiths.
