Balrothery West (Irish: Baile an Ridire Thiar[1]) is one of the baronies of Ireland.
[2] Balrothery, thus once a feudal title of nobility, was later split into eastern and western divisions.
[3] The barony was created soon after the Norman invasion of Ireland by Hugh de Lacy, Lord of Meath as his own feudal barony, held directly from himself in capite.
There are nine civil parishes in the barony: Naul, Westpalstown, Ballyboghil, Garristown, Ballymadun, Palmerstown, Hollywood, Clonmethan, Grallagh.
[4] Population centres include Garristown, Naul, Oldtown and Ballyboughil.
