The tricolour of green, white and orange flies over Government Buildings in Dublin, over barracks, county halls and schools, from GAA grounds and at countless homes on St Patrick’s Day. Next to it come the flag of the European Union, county and provincial flags, club flags and company flags on flagpoles at business parks. The rules behind them are unusually light: the Constitution names the flag, and the Department of the Taoiseach publishes guidelines on how it is flown, but there is no flag law. Whether a flagpole may be put up is a matter for planning law and the local council. This section brings together what applies to flag flying and flagpoles in Ireland, with sources from Irish legislation and government bodies.

The essentials

  • Flag days: The guidelines name five days on which the National Flag flies from all State buildings, from the St Brigid’s Day public holiday to the National Day of Commemoration. The dates are in the guide to flag days.
  • Who may fly flags: Anyone can fly the tricolour, and the guidelines have no statutory force. The details are in the guide to flag flying rules.
  • Half-mast: Two-thirds of the way up, with at least the depth of the flag between flag and top, never below the middle of the pole. More in the guide to half-mast.
  • Size: The flag is twice as wide as it is high and may be made to any convenient size. The flag size calculator shows the size an Irish supplier lists for each pole height.
  • Buying: What affects the price is explained in the guides to buying a flagpole and buying a flag.
  • Planning: There is no specific exemption for flagpoles put up by individuals, and the council can give a section 5 declaration. More in the guide to installing a flagpole.

Constitution, guidelines and responsible bodies

Article 7 of Bunreacht na hÉireann, the Constitution of Ireland, states: “The national flag is the tricolour of green, white and orange.” The flag was adopted by the Irish Free State in 1922 and formally confirmed as the National Flag in the Constitution of 1937.

Beyond that article there are no statutory requirements. The Department of the Taoiseach has general responsibility for the National Flag, and its role is advisory: it publishes the guidelines “The National Flag”, most recently updated in September 2025, which cover the design of the flag, when and where it is flown, the order of flags, half-mast, funerals, hoisting and lowering, and respect for the flag. According to the Department, observing the guidelines is a matter for each person, and the flag is expected to be treated with appropriate respect at all times.

The State’s own emblem is not the flag but the harp. It appears on the seal of the President, on Irish coins and, as a gold harp with silver strings on blue, on the flag of the President.

The flagpole in Ireland

There are no national rules on what a flagpole must look like. Under the Planning and Development Act 2000, all development needs planning permission unless it is exempted, and the Planning and Development Regulations 2001 exempt flags and flagpoles of State authorities and a single roof-mounted business flag. In 2012 the Minister of State told the Dáil that there is no specific exemption for flagpoles erected by individuals. An Irish flagpole supplier lists a 900 × 1800 mm flag for poles of 2 to 7 metres and larger flags for taller poles. More in the guides to types of flagpoles and flagpole heights.

Northern Ireland is part of the United Kingdom, and its flag rules are covered in the guides to the United Kingdom.

Frequently asked questions

Is there a law on how the Irish flag is flown?

No. Article 7 of the Constitution states that the national flag is the tricolour of green, white and orange, but there are no statutory requirements on how it is flown. The Department of the Taoiseach publishes guidelines, and according to the Department, observing them is a matter for each person.

Can anyone fly the Irish flag?

Yes. The guidelines of the Department of the Taoiseach describe how the National Flag is flown by the State and note that many private individuals and businesses also fly it on the main flag days. They expect the flag to be treated at all times with appropriate respect by those who use it.

Does a flagpole need planning permission in Ireland?

Under the Planning and Development Act 2000, all development needs planning permission unless it is exempted. The Planning and Development Regulations 2001 exempt flags and flagpoles of State authorities and one roof-mounted business flag, but according to a 2012 ministerial answer there is no specific exemption for flagpoles erected by individuals. A section 5 declaration from the council settles whether a particular flagpole is exempt.

What are the Irish flag days?

According to the guidelines, the National Flag is flown from all State buildings with a flagpole on the St Brigid’s Day/Imbolc public holiday, St Patrick’s Day, Easter Sunday and Easter Monday, and the National Day of Commemoration on the Sunday closest to 11 July. It is also flown daily at all military posts and at a limited number of State buildings.

How far down is a flag at half-mast in Ireland?

The guidelines describe half-mast as two-thirds of the way up the flagpole, with at least the depth of the flag between its top and the top of the pole. The flag is never below the middle point of the staff.
