A Biblical canon or canon of scripture is a list or set of Biblical books which establishes the names of books considered to be authoritative as scripture by a particular religious community, generally in Judaism or Christianity. This technical term is late and Christian, but the idea is Jewish. The internal wording of the text can also be specified, for example: the Masoretic Text is the canonical text for Judaism, and the King James Version is the canonical text for the King-James-Only Movement, but this is not the general meaning of canon.

These lists, or canons, have been developed through debate and agreement by the religious authorities of those faiths. Believers consider these canonical books to be inspired by God or to express the authoritative history of the relationship between God and his people. Books excluded from a particular canon are considered non-canonical — however, many disputed books considered non-canonical or even apocryphal by some are considered Biblical apocrypha or Deuterocanonical or fully canonical, by others. There are differences between the Jewish and Christian canons, and between the canons of different Christian denominations. The differing criteria and processes of canonization dictate what the communities regard as the inspired books.

The canons listed below are usually considered closed (i.e., books cannot be added or removed ). The closure of the canon reflects a belief that public revelation has ended and thus the inspired texts may be gathered into a complete and authoritative canon. By contrast, an open canon permits the addition of additional books through the process of continuous revelation. In Christian traditions, continuing revelation is most commonly associated with The Church of Jesus Christ of Latter-day Saints (LDS Church), the Religious Society of Friends (Quakers), and with some denominations of Pentecostal and Charismatic Christianity.
