Coolavin (Irish Cúl ó bhFionn) is a historical barony in south County Sligo, Ireland.[1] It was created from the ancient túath of An Corann.
The O'Garas were originally Lords of Coolavin. They were succeeded by the MacDermotts, a family of the Milesian clans, who still claim their head to be the Prince of Coolavin to this day.[2] [3]
