Balrothery East

Balrothery East () is one of the baronies of Ireland. Originally part of the Lordship of Meath, it was then constituted as part of the old county of Dublin. Today, it lies in the modern county of Fingal. 
The barony of Balrothery was created by Hugh de Lacy, Lord of Meath as his own feudal barony, held directly from himself "in capite". His vassals were commonly called "De Lacy's Barons". Balrothery, thus once a feudal title of nobility, was later split into eastern and western divisions.
At the heart of the barony is the civil parish of Balrothery in the northwest of the barony, one of eight civil parishes in the barony.
