The former county of Dublin was divided into nine baronies. While baronies continue to be officially defined units, they are no longer used for many administrative purposes. The last boundary change of a barony in Dublin was in 1842 when the barony of Balrothery was divided into Balrothery East and Balrothery West. Their official status is illustrated by Placenames Orders made since 2003, where official Irish names of baronies are listed under "Administrative units". The boundaries of Fingal do not respect the boundaries of the baronies. As a result, only three baronies are entirely contained in the county: Balrothery East, Balrothery West, and Nethercross. Parts of three baronies are also contained in the county: Castleknock, Coolock, and Newcastle.
