Abbahu was a Jewish Talmudist, known as an amora, who lived in the Land of Israel, of the 3rd amoraic generation (about 279-320), sometimes cited as R. Abbahu of Caesarea (Ḳisrin). His rabbinic education was acquired mainly at Tiberias, in the academy presided over by R. Johanan, with whom his relations were almost those of a son (Yer. Berakhot ii.4b; Gittin 44b; Bava Batra 39a). Wikipedia
