Puffin Island is an Irish Wildbird Conservancy reserve on a small island to the south of Valentia Island near Portmagee, County Kerry and separated from the mainland by a narrow sound. It holds some thousands of pairs of Manx Shearwaters, Storm Petrels and Puffins and smaller numbersof other breeding seabirds.

The island may only be landed up on with the consent of IWC which tends to withhold permission from all except those carrying out bona fide research on the birds. Fishing boats can be chartered in Portmagee.

The island can be seen quite well from the sea by the visitor who takes a boat trip to the Skelligs from Portmagee.
