How Many Counties in Ireland? 32 Counties Explained

Anyone who has ever looked at a map of Ireland has noticed its patchwork of counties — a system that dates back centuries and still shapes identity today. There are 32 counties across the island, split between the Republic of Ireland (26) and Northern Ireland (6).

Are there 32 counties in Ireland?

Yes — the island of Ireland has exactly 32 traditional counties, a number that dates back to the Norman era and was solidified in the 19th century (Ireland.com — Ireland’s official tourism body). After the partition of 1921, 26 of these counties became the Republic of Ireland (an independent sovereign state) and six became Northern Ireland, a constituent country of the United Kingdom (Wikipedia — the free encyclopedia).

What is the difference between the Republic of Ireland and Northern Ireland?

• Republic of Ireland: 26 counties, independent since 1922, uses counties as local-government units (with some modern administrative divisions).
• Northern Ireland: 6 counties (Antrim, Armagh, Down, Fermanagh, Londonderry, Tyrone) — counties ceased to be used for local government there in 1973 (Wikipedia — the free encyclopedia).

How many counties are in each province?

Ireland is divided into four provinces, each containing a specific number of the 32 counties:

• Leinster: 12 counties
• Munster: 6 counties
• Connacht: 5 counties
• Ulster: 9 counties (3 in the Republic — Cavan, Donegal, Monaghan — and 6 in Northern Ireland) (Ireland.com — Ireland’s official tourism body)

Why this matters: the province-county system is embedded in everyday Irish life — from postal addresses to sports rivalries. Ask any Irish person their county and you’ll get a story, often tied to one of the four provincial cups in GAA.

The implication: understanding this distinction clarifies why political borders don’t fully capture Irish identity — the 32-county model persists in GAA, genealogy, and everyday pride.

What are the 32 counties in Ireland?

Here they are — all 32, grouped by province, with their current country affiliation. The full list covers every county on the island (Ireland.com — Ireland’s counties and provinces).

Alphabetical list of all 32 counties

Republic of Ireland (26): Carlow, Cavan, Clare, Cork, Donegal, Dublin, Galway, Kerry, Kildare, Kilkenny, Laois, Leitrim, Limerick, Longford, Louth, Mayo, Meath, Monaghan, Offaly, Roscommon, Sligo, Tipperary, Waterford, Westmeath, Wexford, Wicklow.

Northern Ireland (6): Antrim, Armagh, Down, Fermanagh, Londonderry, Tyrone (Wikipedia — the free encyclopedia).

List by province

Each province groups its counties — here’s the full breakdown:

The implication: if you’re planning a road trip or researching ancestry, knowing the province group helps narrow your search. For example, “County Mayo” immediately places you in Connacht, famous for its rugged coastline and pilgrimage mountain Croagh Patrick.

The pattern: province groupings simplify travel planning and ancestry research — they’re the key to unlocking Ireland’s local records and landscapes.

What is the third biggest county in Ireland?

The third largest county on the island by area is Galway, covering 6,148 km² (Wikipedia — List of Irish counties by area). First is Cork (7,499 km²), second is Mayo (5,585 km²).

Top 5 largest counties by area

Here are the five biggest counties by land area:

The trade-off: big counties like Cork and Galway offer the most diverse landscapes — coast, mountains, farmland — but smaller counties like Louth (826 km²) are easier to explore in a weekend (Wikipedia — List of Irish counties by area).

The catch: size doesn’t equal experience — Louth packs history and coastline into a compact area, making it ideal for short trips.

What is the most forgotten county in Ireland?

In online forums and travel polls, Leitrim is consistently mentioned as the most “forgotten” county (Wikipedia — County Leitrim). It has the smallest population of any county (about 32,000) and is one of the least visited. Other contenders include Longford and Monaghan.

Factors that make a county “forgotten”

• Low population: Leitrim’s population density is the lowest in the Republic.
• Limited tourism infrastructure: Few major attractions compared to Kerry or Cork.
• Off the main travel routes: No major airports or motorways pass through.

The catch: “forgotten” doesn’t mean unworthy. Leitrim has hidden gems — the Shannon-Erne Waterway, Glencar Waterfall — for travellers who venture off the beaten path.

What’s the prettiest town in Ireland?

Beauty is subjective, but a handful of towns consistently top lists. Kinsale (Cork), Dingle (Kerry), Westport (Mayo), and Adare (Limerick) are frequent winners in tourism awards (Wikipedia — List of towns in the Republic of Ireland).

Top towns by county

• Kinsale, Cork: Colourful harbour town, praised for its food scene.
• Dingle, Kerry: Gaeltacht (Irish-speaking) town with dramatic coastal views.
• Westport, Mayo: Georgian architecture, tree-lined streets, Croagh Patrick backdrop.
• Adare, Limerick: Thatched cottages and medieval churches.

For visitors choosing between these, the decision often comes down to what you value most — seafood (Kinsale), Irish language and music (Dingle), walking trails (Westport), or historic charm (Adare).

Summary: Why the 32 counties still matter

Whether you’re tracing your great-grandparents or planning a trip, the 32-county framework is more than a list — it’s a cultural compass. In GAA, counties compete in the All-Ireland championships regardless of the border. In genealogy, a county name is the key to parish records. For the traveller, each of the 32 offers a distinct flavour of landscape and hospitality. The modern political split into 26+6 is a reality, but the 32 remain the map that most Irish people carry in their heads.
