Dodai ben Nahman was a Babylonian-Jewish scholar of the eighth century CE and gaon of the Talmudic academy at Pumbedita (761-764). Little is known of his life. He was a brother of the famous Judah ben Nahman, gaon at Sura (759-762), and with him was instrumental in preventing the eventual founder of Karaism, Anan ben David from succeeding to the exilarchate made vacant by the death of Solomon ben Hasdai and Isaac Iskoy ben Solomon, Anan's kinsmen.
