Caucasian Iberians is a Greco-Roman designation for the population of Caucasian Iberia, a Kartvelian (Georgian) speaking people in the east and southeast Transcaucasus region in Antiquity and Middle Ages. In the southwest, Iberians extended into Anatolia, inhabiting interior lands beside Colchians, who lived along the littoral area. Ancient Caucasian Iberians are considered to be the ancestors of modern eastern Georgians as well the Laz people, another Kartvelian-speaking group.
