Valentia Island (Irish: Dairbhre) is one of Ireland's westernmost points, lying off the Iveragh Peninsula in the southwest of County Kerry, Ireland. It is linked to the mainland by the Maurice O'Neill Memorial bridge at Portmagee, as well as by a ferry which sails from Reenard Point to Knightstown, the island's main settlement. The permanent population of the island is 650, and the island is approximately 11 kilometres (6.8 mi) long by almost 3 kilometres (1.9 mi) wide.
