Coolock (Irish:An Chúlóg)^{[4 1]} is one of thebaronies ofIreland. It was constituted as part of the old county ofDublin. Today, it covers much of the northern parts of the city ofDublin and the south-eastern part of the moderncounty ofFingal. At the heart of the barony is thecivil parish of the same name -Coolock - which is one of twenty civil parishes in the barony.

Baronies were created after theNorman invasion of Ireland as subdivisions of counties and were used for administration. While baronies continue to be officially defined units, they are no longer used for many administrative purposes. They have been administratively obsolete since 1898. Nevertheless, they continue to be used in land registration and specification such as in planning permissions. In many cases, a barony corresponds to an earlierGaelictúath which had submitted to the Crown. However, the status of barony is still used in modern times^[1][2][3]

It is one of seven and a half baronies that used to comprise the oldcounty of Dublin.^[4] It stretches fromDublin Airport and theMalahide estuary to theRoyal Canal andRiver Tolka estuary (from north to south) and from thePhoenix Park toDublin Bay (from west to east). It is located between the baronies ofNethercross (to the north),Castleknock (to the west) and Dublin City (to the south). The northern two-thirds of the barony is now administered byFingal County Council while the southern third is subject toDublin City Council.

For convenience, the table below groups the barony's twentycivil parishes by their location in one of the modernlocal authority areas. Some parishes, however, straddle both areas.

Note 1 In 1773, during the reign of KingGeorge III of Great Britain, the parishes were assessed as having the acreage as set out in the above table.^[5] In addition, the parishes of Kilossory and Kilbegh are mentioned as being in the barony with 900 and 500 acres respectively. Today, Killossory is in the barony ofNethercross but the date of its presumed transfer from this barony is unknown. The identity of Kilbegh is unclear although Kilbarrack may be a candidate. The source makes no mention of St George's parish.

Note 2 The parish of Clonturk is now mainly identified with the district ofDrumcondra.

Note 3 The parish is St George is split between this barony and the barony of the City of Dublin. That part of the parish which lies in Coolock is bounded by theRiver Tolka to the north,Dublin Bay to the east and theRoyal Canal to the south.

Note 4 Anexclave of the parish of Swords lies in the barony. It is a single parcel of land, just over 5 acres in area - thetownland of Glebe.^{[4 22]} Today, it is the site of the Metropoint Business Park.^{[citation needed]}
