The Corcu Duibne, which means "seed or tribe of Duibhne" (the name of a goddess), was a notable kingdom in prehistoric and medieval County Kerry, Ireland which included the Dingle Peninsula, the Iveragh Peninsula and connecting lands. The tribe belonged to the Érainn and claimed descent from the legendary Conaire Mór, possibly making them distant cousins of such far off kingdoms as Dál Riata in Ulster and Scotland, as well as the closer Múscraige and Corcu Baiscind. All the tribes belonged to the Síl Conairi of legend and ultimately traced their descent from the Clanna Dedad.
