Abas (Greek: Ἄβας) was an ancient Greek sophist and a rhetorician about whose life nothing is known. The Suda ascribes to him historical commentaries (in Greek ιστoρικά απoμνηατα) and a work on rhetoric (in Greek τέχνη ρητoρική). What Photius in his Myrobiblion quotes from him, belongs probably to the former work.
