Coole (from Irish An Chúil 'corner') is a barony in County Fermanagh, Northern Ireland.

[2] To its west lies Upper Lough Erne, and it is bordered by three other baronies in Northern Ireland: Knockninny to the west; Magherastephana to the north; and Clankelly.

[2] It also borders three baronies in the Republic of Ireland: Dartry to the east; Tullygarvey and Loughtee Lower to the south.

Coole is based upon the ancient territory of Cuil, which was frequently referred to as the residence of the O'Cassidys (Irish: Ó Caiside).

In the Annals it appears as Cuil na nOirear, which may have applied to an old half-barony near Enniskillen.
