This is a list of thebaronies ofIreland. Baronies were subdivisions ofcounties, mainlycadastral but with some administrative functions prior to theLocal Government (Ireland) Act 1898.
The final catalogue of baronies numbered 331, with an average area of 255 km2 (98 sq mi; 63,000 acres); therefore, each county was divided, on average, into 10 or 11 baronies. A figure of 273 is also quoted, by combining those divided into half-baronies, as by East/West, North/South, or Upper/Middle/Lower divisions.
Every point in Ireland is in precisely one of the listed divisions. However, the municipal area of the four cities with barony status in 1898 has extended since then into the surrounding baronies. Prior to 1898, the baronies around Dublin City were shrunk accordingly as they ceded land to the expanding city; but there is now land which is both within the current city boundaries and within one of the pre-1898 county baronies. Notably, the Barony of Dublin, created in 1842, is entirely within the city, although still separate from the Barony of Dublin City.
Creation date is sometimes specified as an upper bound (and possibly a lower bound) rather than the precise year:

Notes:
The names of more recently abolished baronies are generally preserved in the successor baronies; e.g. "Massereene" was split into "Massereene Lower" and "Massereene Upper", and "Coshmore" and "Coshbride" were merged intoCoshmore and Coshbride.
TheMunicipal Corporations (Ireland) Act 1840 (3 & 4 Vict. c.108) separated the rural hinterland or "liberties" from some of the counties corporate, restricting their jurisdiction to the relevant municipal town, borough, or city. TheCounties and Boroughs (Ireland) Act 1840 (3 & 4 Vict. c.109) provided that the rural area would form a new barony of the adjacent county until the county Grand Jury should decide to allocate it to an existing barony. The reallocation happened quickly in some cases, slower in others, and not at all in three cases: the baronies ofCork[85] andGalway,[86] and the Louth barony of Drogheda.

In 1412, Henry IV issued a charter uniting them into one borough, which was granted county status and full independence from both counties. Drogheda was followed by Dublin (1548), Carrickfergus (1569), Waterford (1574), Cork (1608), Limerick and Kilkenny (both 1609) and Galway (1610).
It was divided into baronies in 1585, which were in fact the traditional territories of the various branches of the Mac Mahons
At what time the Barony of Decies was divided into two distinct Baronies is uncertain; at present it is distinguish'd at the Assizes and Sessions into two parts, viz. Decies within and Decies without Drum.
On the other hand the baronies of the North Liberties of Limerick and of Kilculliheen to the north of Waterford city were not used in the 1851 or 1861 censuses but are shown separately in 1881.
