Sosthenes (Greek, "safe in strength") was the chief ruler of the synagogue at Corinth, who, according to the New Testament, was seized and beaten by the mob in the presence of Gallio, the Roman governor, when he refused to proceed against Paul at the instigation of the Jews (Acts 18:12-17). The motives of this assault against Sosthenes (an assault made by the Greeks according to Acts 18:17) are not recorded.
