Lurg (from Irish Lorg 'mark, trail or track'[1]) is a barony situated in the north of County Fermanagh, Northern Ireland.

[2] To its south lies Lower Lough Erne, and it is bordered by four other baronies in Northern Ireland: Magheraboy to the south; Tirkennedy to the south-east; Omagh West to the north; and Omagh East to the east.

[1][3] Prior to this, Lurg was the base of the O'Monaghan (Irish: Ó Manacháin), thought to be descended from the original inhabitants of the area, the Fir Manach, from which County Fermanagh gets its name.

[4][5] According to 19th century genealogist John O'Hart, the barony was also home to the Muintir Taithligh "chiefs of Hy-Laoghaire, of Lough Lir, a district which lay in the barony of Lurg, near Lough Erne, towards Tyrone.

"[6] O'Hart also notes that the lord of Lurg in A.D. 924, Fergus MacDuilgen, is listed in the Annals of the Four Masters, although not chronicled in the lists of families and clans of the scholar poet Seán Mór Ó Dubhagáin.
