Religious organisations in Ireland
Religious organisations in Ireland are not registered or licensed as religious organisations. There is no register of churches and no body that authorises one. Anyone may found a religious organisation, and the State takes no view on doctrine.
What follows is the main bodies operating in Ireland, what each one actually is, and the two public registers that do apply to them.
Finding an individual church
If what you want is a specific church, with a service time and an address, that is a different question from the one this page answers and the list below will not help.
Christianity.ie is a directory of Christian churches in Ireland, browsable by denomination and by county, listing service times and contact details. Its coverage is strongest on Catholic parishes, running to a couple of thousand churches across all thirty two counties. The other denominations are thinner, so for a Presbyterian or Methodist congregation you may do better going to that church’s own site.
The main Christian churches
| Body | What it is |
|---|---|
| Catholic Church in Ireland | The largest church by membership. Organised into four provinces and twenty six dioceses whose boundaries predate the border and ignore it |
| Church of Ireland | Anglican, and the second largest Christian denomination. All island, with two provinces |
| Presbyterian Church in Ireland | The largest Protestant denomination in Northern Ireland, with congregations across the island |
| Methodist Church in Ireland | All island, and historically close to the Church of Ireland and the Presbyterians through the Irish Council of Churches |
| Non-Subscribing Presbyterian Church of Ireland | A separate denomination from the Presbyterian Church in Ireland, not a branch of it. The distinction is doctrinal and dates to the nineteenth century |
| Religious Society of Friends in Ireland | The Quakers. Present in Ireland since the seventeenth century, small in number and long associated with relief work |
| Association of Baptist Churches in Ireland | The main Baptist grouping. Individual Baptist churches are self governing, so not every Baptist congregation belongs to it |
| Redeemed Christian Church of God Ireland | One of the larger Pentecostal networks, founded in Nigeria and established here through migration since the 1990s |
| The Salvation Army | A church as well as a relief organisation, which people frequently get wrong in the other direction |
Orthodox Christianity has grown substantially through migration since the 1990s and is served by Greek, Russian and Romanian jurisdictions with parishes in Dublin and the larger cities. There is no single Irish Orthodox body, so the parish or the jurisdiction is the right place to look rather than a national office.
The same applies to the wider Pentecostal and independent evangelical churches. Many are single congregations or small networks, a good number founded by and serving migrant communities, and no umbrella organisation covers them all.
Other faith communities
| Body | What it is |
|---|---|
| Islamic Foundation of Ireland | The oldest Muslim organisation in the country, running the mosque on the South Circular Road in Dublin |
| Islamic Cultural Centre of Ireland | The centre and mosque at Clonskeagh in Dublin, the largest in Ireland |
| Jewish Representative Council of Ireland | The representative body for a small community centred on Dublin, whose history in the city runs back well over a century |
| Baha’i Community of Ireland | The national body for the Baha’i Faith in Ireland |
Hindu, Sikh and Buddhist communities are all established in Ireland, largely through migration, and are served by individual temples, gurdwaras and centres rather than by a single national organisation. As with the Orthodox churches, the individual centre is the place to start.
Representative and support organisations
Not churches, but organisations that represent, support or advocate for religious life in Ireland. All four below are on the public Register of Charities, checked against the register download of 19 July 2026.
| Body | What it is |
|---|---|
| Association of Leaders of Missionaries and Religious of Ireland | Known as AMRI. The representative body for the leaders of Catholic missionary and religious congregations in Ireland |
| Vocations Ireland | A registered charity working with Catholic religious congregations and orders on vocations |
| Accord Catholic Marriage Care Service | Marriage preparation and relationship counselling, operating across the island for over sixty years |
| The Iona Institute | A registered charity advocating for religious and family perspectives in Irish public debate |
This is not a complete list. Religious congregations, orders and diocesan agencies run a great many registered charities between them, and the Register of Charities is the place to see the full picture. Filtering it by the charitable purpose “advancement of religion” is the quickest way in.
Secular and ecumenical bodies
Not religious organisations themselves, but they occupy the same ground and appear on the same registers.
| Body | What it is |
|---|---|
| Humanist Association of Ireland | A non religious body that nominates solemnisers, which is why it appears on the marriage register alongside the churches |
| Irish Council of Churches | The ecumenical body bringing together most of the main Protestant and Orthodox churches on the island |
Checking a religious organisation
Two registers apply, and between them they answer most of what people actually want to know.
The Register of Charities
Most established religious organisations in Ireland operate as registered charities, because the advancement of religion is a charitable purpose in Irish law. Registration with the Charities Regulator is a legal requirement for a body operating as a charity, and the register is public.
This is the most useful check available. It confirms the organisation exists as a formal entity, names its trustees, and shows it is subject to reporting obligations. If a religious organisation asking you for money is not on it, that is worth a question.
The Register of Solemnisers
To legally solemnise a marriage in Ireland, a person must be entered in the Register of Solemnisers, maintained by the General Register Office and published at gov.ie. That applies to religious and secular ceremonies alike, alongside HSE registrars.
Solemnisers are nominated by their religious or secular body rather than applying individually, and each body has a registered nominator responsible for keeping its entries accurate. Temporary registration exists for someone solemnising one specific marriage or for a fixed period, which is how visiting clergy and one off celebrants are handled.
The practical point: if you are planning a wedding, the person conducting it has to be on this register on the day, or the marriage is not legally solemnised. Check the name rather than assuming, particularly if the celebrant is travelling in or is not attached to a local congregation.
What none of this establishes
Neither register says anything about whether an organisation is well run, whether its beliefs are what it says they are, or whether it is a safe place to send anybody. Charity registration is a financial and governance matter. Solemniser registration is a marriage law matter. Both are worth checking and neither is a character reference.
For an organisation that is neither a charity nor a solemniser, there may be no public record beyond a company registration, which you can look up through the Companies Registration Office.
Checked . Registers move and bodies get renamed. If a link here is dead, the register almost certainly still exists somewhere else on the same organisation's site.
