Kinnagoe Bay (Irish: Bá Chionn an Ghabha) is a secluded beach in Inishowen, County Donegal, Ireland. It is known for being the location of the wreck of the Armada ship La Trinidad Valencera on 16th September 1588, in memory of which a plaque is mounted. The beach is accessible by a weaving road from the top of the hill. There is a small car park at the beach which gets very busy during the summer.
