Beara () or the Beara Peninsula is a peninsula on the south-west coast of Ireland, bounded between the Kenmare river (actually a bay) to the north side and Bantry Bay to the south. It contains two mountain ranges running down its centre: the Caha Mountains and the Slieve Miskish Mountains. The northern part of the peninsula from Kenmare to near Ardgroom is in County Kerry, while the rest forms the barony of Bear in County Cork.
