Tirkennedy (from Irish Tír Cheannada 'country of the long-head') is a barony in County Fermanagh, Northern Ireland.

[2] To its west lies Lower Lough Erne and south Upper Lough Erne, and it is bordered by seven other baronies: Clanawley and Magheraboy to the west; Lurg and Omagh East to the north; Clogher to the east; Magherastephana and Knockninny to the south.

Rather it takes its name from the epithet of Fergus son of Cremthann, the eponymous ancestor of the Ui Chremthainn, the predominant tribe of the western Airgialla.

[4][3] Chieftains of Tirkennedy at the beginning of the Maguire’s reign over Fermanagh in the late 1200s were the Magunshinan, originally Mac Uinsionnain but anglicised to Nugent.

[7] The early Anglicisation of "Tircannada" recorded in the 1609 escheated counties map is claimed as being more accurate than the present form of "Tirkennedy".
