People of western Co. Kerry, especially on both the north and the south shores of Dingle Bay. In some writings Corca Dhuibhne denotes the Dingle peninsula specifically. The Cailleach Bhéirre [Old Woman of Beare] was of the Corcu Duibne, but their (perhaps divine) ancestress may have been Dob [h]inia. Cú Roí had his fortress in their territory. One of the highest concentrations of stones bearing ogham inscriptions is found in land once occupied by the Corcu Duibne. Among the Corcu Duibne also was Gleann na nGealt, a valley filled with wild men.
