The Dingle Peninsula (Irish: Corca Dhuibhne - anglicized as Corkaguiny, the name of the corresponding barony) is the northernmost of the major peninsulae in County Kerry. Its ends beyond the town of Dingle at Dunmore Head, the westernmost point of Ireland.

The Dingle Peninsula is named after the town of Dingle. The peninsula is also commonly called Corca Dhuibhne (Corcu Duibne) even when those referring to it are speaking in English. Corca Dhuibhne, which means "seed or tribe of Duibhne" (an Irish personal name), takes its name from the túath (people, nation) of Corco Dhuibhne who occupied the peninsula in the Middle Ages and who also held a number of territories in the south and east of County Kerry.

The peninsula exists because of the band of sandstone rock that forms the Slieve Mish mountain range at the neck of the peninsula, in the east, and the unnamed central mountain range further to the west. Ireland's highest mountain outside Macgillycuddy's Reeks, Mount Brandon at 951 m, forms part of a beautiful high ridge with stunning views over the peninsula and North Kerry.

Dingle (Irish: An Daingean / Daingean Uí Chúis, meaning "Ó Cúis' fort") is a town in County Kerry, Ireland. The only town on the Dingle Peninsula, it sits on the Atlantic coast, about 50 kilometres (30 mi) southwest of Tralee and 71 kilometres (40 mi) northwest of Killarney.

Principal industries in the town are tourism, fishing and agriculture: Dingle Mart (livestock market) serves the surrounding countryside. In 2006 Dingle had a population of 1,920. Dingle is situated in a Gaeltacht region.

The town was developed as a port following the Norman invasion of Ireland. By the thirteenth century more goods were being exported through Dingle than Limerick, and in 1257 an ordinance of Henry III imposed customs on the port's exports. By the fourteenth century, importing wine was a major business. Maurice FitzGerald, 1st Earl of Desmond, who held palatine powers in the area, imposed a tax on this activity around 1329. By the sixteenth century, Dingle was one of Ireland's main trading ports, exporting fish and hides and importing wines from the continent of Europe. French and Spanish fishing fleets used the town as a base.
