Abrahamic religions (also Abrahamism) are the monotheistic faiths emphasizing and tracing their common origin to Abraham or recognizing a spiritual tradition identified with him. They are one of the three major divisions in comparative religion, along with Indian religions (Dharmic) and East Asian religions (Taoic). As of the early twenty-first century^[update], it was estimated that 54% of the world's population (3.8 billion people) considered themselves adherents of the Abrahamic religions, about 30% of other religions, and 16% of no religion.

The three major Abrahamic religions are, in chronological order of founding, Judaism, Christianity, and Islam. Judaism regards itself as the religion of the descendants of Jacob, a grandson of Abraham. It has a strictly unitary view of God, and the central holy book for almost all branches is the Masoretic Text as elucidated in the oral Torah.

Christianity began as a sect of Judaism in the Mediterranean Basin of the 1st century CE and evolved into a separate religion—the Christian Church—with distinctive beliefs and practices. Jesus is the central figure of Christianity, considered by almost all denominations to be divine, typically as one person of a Triune God. The Christian Bible is usually held to be the ultimate authority, alongside Sacred Tradition in some denominations (such as Roman Catholicism and Eastern Orthodoxy).
