Rabīʿa is a major North Arabian (Adnanite) tribal confederation descended from Rabīʿa ibn Nizar, one of the two main branches of Adnanite Arabs alongside Mudhar. Its branches include Abd al-Qays, Anizah, Banu Bakr, Taghlib, and others, inhabiting regions from eastern Arabia to Mesopotamia. Several branches were Christian before Islam, with some converting later, and the tribe played significant roles in early Islamic history and beyond. Notable descendants include prominent poets, warriors, and rulers, with royal families such as the Al Saud and Al Khalifa tracing their lineage to Rabīʿa.
