| 1386–1542 | The heraldic banner of the Lordship of Ireland was based on its coat of arms. The earliest depiction of the 'triple crown' motif is found on the arms granted by Richard II to Robert de Vere as Lord of Ireland in 1386. "They were borne, apparently as the arms of Ireland, in the funeral procession of Henry IV in 1413. They appear as a device on the Irish coinage of Edward IV (1461–83), Richard III (1483–85), Henry VII (1485–1509), and the pretender, Lambert Simnel (1487). Edward IV specified them as the Irish arms in an indenture of 1483".[1] The 'triple crown' motif has been traditionally associated with St. Edmund, the Saxon king of East Anglia (855–869) who is today one of the patron saints of England. The flag of East Anglia was a St. George's Cross with a blue coat of arms featuring three gold crowns – visually similar to the arms of the province of Munster. In his work 'Vicissitudes of Families', Bernard Burke, the Ulster King of Arms, proposed that St. Edmund's Banner was borne during the Norman Invasion of Ireland. A section of Christ Church Cathedral in Dublin is dedicated to St. Edmund, although his iconography is not displayed. | The banner of the Lordship of Ireland was based on the arms and feature three golden crowns ordered vertically on a blue background with a white border. It is blazoned: "Azure, three crowns in pale Or, bordure Argent." |
| 1542–1801 | | A silver stringed gold harp on a blue field. |
| 1821–1922 | Flag of the Lord Lieutenant of Ireland. This was granted in 1821, by the Lords Commissioners of the Admiralty under royal warrant, "to prevent the Inconvenience experienced for want of a flag distinguishing the presence of the Lord Lieutenant on board His Majesty's ships".[2] The flag became defunct when the office was abolished by the Irish Free State (Consequential Provisions) Act 1922. | The flag of the United Kingdom defaced with the coat of arms of Ireland. |
| 1783–present | The St. Patrick's Saltire, also known as the Cross of St Patrick, after Saint Patrick, the main patron saint of Ireland. "The Saltire became an established Irish symbol in 1783 with the founding of the Order of Saint Patrick by King George III to mark the legislative independence of the Kingdom of Ireland which lasted from 1783 to 1801. The Saltire is believed to derive from the arms of the FitzGeralds who were the Earls of Kildare and later Dukes of Leinster. Incidentally, Kildare County Council uses the Saltire on its coat of arms, as do Cork City and Trinity College Dublin, that both feature two flags – St. George's Cross and St. Patrick's Saltire. The flags of Queen's University Belfast and the Royal College of Surgeons in Ireland use the symbol and it can also be found on the badge of the Police Service of Northern Ireland (PSNI)".[3] The flag has been used for almost 30 years by local authorities in Downpatrick for St. Patrick's Day. In addition, Church of Ireland flies this flag on special religious days throughout the island. While the saltire represents Ireland on the flag of the United Kingdom, this use is disputed by some Irish nationalists who have described the saltire as an "1800 English invention [..] for a people who had never used it".[4] | The Saint Patrick's Saltire features a red saltire on a white field. In heraldry these arms are blazoned: "Argent, a saltire gules". |
| 1642–present | The green harp flag of the 17th century Confederacy of Ireland and an unofficial flag of Ireland during the 18th and 19th century. Variants have been used as the basis for numerous flags of Ireland. It was used by the Irish team at the 1930 British Empire Games. | A silver-stringed gold cláirseach harp on a green field. |
| ???–present | The Four Provinces Flag of Ireland. This flag, and variants of it, have been used by various all-Ireland sports teams and cultural organisations. | The arms of the four provinces of Ireland are shown in quadrants. The order in which the arms appear varies. | |

| 1947–present | The Irish Naval Jack was adopted in 1947 after the establishment of the Naval Service (Ireland) (an tSeirbhís Chabhlaigh) in 1946. It is flown at the bow and used to represent Ireland along with the Naval Ensign. The Naval Jack is flown "by Irish Naval Ships at the Jack staff when at anchor, moored, alongside or when under way and dressed with Masthead Ensigns. It is hoisted and half masted at the same time and in like manner as the Naval Ensign."[6] | The naval jack of the Naval Service of Ireland features a green field with a gold harp with 14 diagonal golden strings. |
| 1996–present | Naval Service Colour Flag | Double-sided square banner. The primary colour is navy blue on both sides. The obverse side carries the Defence Forces badge at the centre superimposed over a pair of crossed silver foul anchors. The colour is bordered by a two-inch wide gold fringe Naval Service. |

| 1966–present | The Military Colours of the 1st Brigade of the Irish Defence Forces were part of a set of six unit Colours that were designed in 1964. It was originally known as the Southern Command until the reorganisation of the army in 2012. There are now only two Brigades responsible for military operations in Ireland. | The Military Colours of the 1st Brigade are a field "divided per bend, or diagonally, yellow above and blue below, with a centrepiece of a stylised ship with a red hull and white sails encircled by a parti-coloured antique crown of yellow and blue. This device is a combination of details of the arms of the province of Munster and the city of Cork." 'Óglaigh na hÉireann' is written across the top, which is the official Irish title for the Defence Forces (Ireland). 'An Cead Briogaid' is written at across the bottom and means '1st Brigade' in Irish. The badge of the Irish Defence Forces is placed in the right-hand corner (fly). |
| 1966–present | The Military Colours of the 2nd Brigade of the Irish Defence Forces were part of a set of six unit Colours that were designed in 1964 and were the first to be completed. They "were carried for the first time in the army parades and marches which formed part of the Dublin celebrations of the fiftieth anniversary of the 1916 rising at Easter 1966". | The Military Colours of the 2nd Brigade are "divided per pale, or vertically, in two stripes, blue and green. The centrepiece shows a rising sun in yellow, on which are superimposed a flaming tower and a yellow harp device. The sun device is from the Irish Volunteer colours of 1914, the tower is from the arms of the city of Dublin and the harp is from the arms of the province of Leinster". Óglaigh na hÉireann is written across the top, which is the official Irish title for the Irish Defence Forces. 'An Dara Briogaid' is written at across the bottom and means '2nd Brigade' in Irish. The badge of the Irish Defence Forces is placed in the right-hand corner (fly). |

| | | The arms of the nine-county province of Ulster form a composite achievement, combining the heraldic symbols of two of that province's best known families, namely the cross of de Burgo and the dexter hand of O Neill (Ua Néill, later Ó Néill) Kings of Ailech and Tír Eoghan. |
| | | The province of Munster has been heraldically symbolised by three golden antique crowns on an azure blue shield. A crown of the type now known as antique Irish forms an integral element of a thirteenth-century crozier head found near Cormac's Chapel on the Rock of Cashel. In the case of the 'king-bishops' of Cashel, the placing of the antique crown on their crozier was a symbolic assertion of their right to the political sovereignty of Munster. |
| | | The arms of Connacht use a dimidiated (divided in half from top to bottom) eagle and armed hand. Ruaidhri O'Conchobhair, King of Connacht, is surmised to have been conceded the arms of Schottenklöster for the Irish monastery founded in Regensburg,[8] which approximate to the Connacht Flag of 1651 |
| | | A silver stringed golden harp on a green background. Possibly the oldest and certainly the most celebrated instance of the use of the harp device on a green field was the flag of Owen Roe O'Neill. It is recorded that his ship, the St Francis, as she lay at anchor at Dunkirk, flew from her mast top 'the Irish harp in a green field, in a flag'. |
| No history of flag use | The ancient Kingdom of Meath (Mide) was represented by the emblem of a king seated on a throne. There is no history of a flag ever being used, however an emblem was used which derived from iconography rather than classic heraldry. "The old province of Meath, which is nearly coextensive with the present day Diocese of Meath, is heraldically personified by a representation of a royal personage seated on a throne... It is, of course, fitting that Meath, wherein stood Tara, the symbolic site of the Kingship of Ireland, should be shown heraldically by a representation of a royal personage, or majesty, seated on a throne. The arms of Meath were apparently used at one time as the arms of Ireland, i.e. a majesty on a sable (black) background, the provincial arms being displayed on an azure (blue) field".[9] | The flag of Mide features a light blue field with a king sitting on a throne. The sceptre and outstretched right hand symbolise sovereignty and justice respectively. Today this emblem is used by the Meath GAA team but not the Meath County Council. | |

| 1885–present | The flag of Dublin City was adopted in 1885 by the Dublin Corporation. In the canton it features 'three burning castles' which are part of the coat of arms of the city that were officially granted in 1607 by the Ulster King of Arms, Daniel Molyneux. The arms was a corruption of the earlier seal of Dublin that featured one castle with three watchtowers on the obverse and a ship on the reverse, whose earliest mention was in 1230. The seal of Dublin was based on the arms of Bristol as King Henry II granted the city to his men of Bristol with the 1171 Charter. This meant that Bristol merchants took control of colonisation of the Dublin city after the Norman invasion of Ireland.[10] The flag is flown over Dublin City Hall, the Mansion House and around the city, both indoors as well as outdoors. It acts as the de facto flag of the Dublin City Council. | The flag of Dublin City features a green field with a gold harp and three white two-towered burning castles on a navy canton. The gold harp represents both Ireland and Leinster, while the three burning castles are the lesser coat of arms of the city. Green and blue are the two national colours of Ireland. |
| 1890–present | Flag of Belfast is a heraldic banner that is based on the shield of the coat of arms of the city. The arms were granted in 1890, two years after Belfast was awarded city status by Queen Victoria. Although the banner was adopted in 1890, it has seldom been used. "The precise origins and meanings of the symbols contained on the Coat of Arms are unknown. But images such as the bell, the seahorse, the ship and the chained wolf were all used by 17th-century Belfast merchants on their signs and coinage. The seahorse, which is used twice, shows the maritime importance of Belfast, as does the ship at the base of the shield".[11] | The flag of Belfast is a horizontal bicolour of white and light blue. It features a silver bell in a red canton, a triangle of Vair(type of heraldic pattern) and a ship on waves with a Saint Patrick's Saltire as a naval ensign and masthead. |
| 2012–present | The flag of Drogheda town was adopted by Drogheda Borough Council in 2012 and features a triband of red and black which are considered to be the 'town colours' and the coat of arms of Drogheda town. The exact origins of the arms are obscure due to the records being lost in a fire. Some believe that the 'castle and ship' element on the shield is derived from the arms of Bristol, in the same way as the 13th century Dublin seal. Others feel that the castle represents Saint Laurence Gate, while the ship stands for the river Boyne and Drogheda port. The 'star and crescent' emblem has the same origin as the coat of arms of Portsmouth and is taken from the arms of Richard I of England (Lionheart) who adopted it during the Third Crusade. The three lions 'passant guardant' are also derived from Richard I who began to use the emblem in 1198 to represent his position as King of the English, Duke of the Normans and Duke of the Aquitaines. These emblems honour the king, during whose reign Drogheda was granted its charter in 1194 by Hugh de Lacy. Since the 'Local Government Reform Act 2014' that came into effect from 1 June 2014, Drogheda Borough Council no longer exists and is now part of Louth County Council. | The flag is a vertical triband of red-black-red and features the coat of arms of Drogheda in the centre. The town's motto reads: Deus praesidium, mercatura decustranslates, which means "God our strength, merchandise our glory". |
| 2013–present | The unofficial flag of Dún Laoghaire–Rathdown County Council was adopted in August 2014. It was originally designed and used for Bratacha 2013 – Ireland's first ever 'Festival of Flags and Emblems'.[12] The design concept was based on a combination of the Dún Laoghaire–Rathdown County Council emblem, the coat of arms and on a loose translation of the County motto: Ó Chuan go Sliabh, meaning ‘from harbour to mountain’. Today the flag flies every weekend at the County Hall in the town of Dún Laoghaire. | The unofficial flag of Dún Laoghaire–Rathdown County Council has a yellow field and features a green shamrock with two strokes – green and blue. The green stroke represents the mountains, while the blue one stands for the sea. This reflects the fact that the county is bordered by the Irish Sea and the Wicklow Mountains. |
| | | The upper flag is simply a banner of arms, with the city arms: Sable a human skeleton Or seated upon a mossy stone proper and in dexter chief a castle triple towered Argent on a chief of the last a cross gules charged with a harp or and in the first quarter a sword erect also gules. The skeleton commemorates the many who starved to death during the Siege of Derry (1688–89). A red flag was hung from St Columb's Cathedral during the siege and a red (or crimson) flag has become a symbol of Protestant identity in the city,[13] used by the Apprentice Boys of Derry,[14] and the "bloody flag" is sometimes described as the flag of the city as well.[15] [16] [17] |
| 2017–present | The Tallaght Unity Flag / An Bratach Aontacht Thamlachta | The Tallaght Unity Flag features a red deer. The green triangle in the lower left corner represents the landscape surrounding Tallaght. The flag also includes three blue, eight-pointed stars on the right side, reflecting a design captured during the Battle of Tallaght in 1867 and with blue representing inclusivity and unity.[18] | |

| 1914–present | The Starry Plough Banner made its first appearance at an Irish Citizen Army meeting on 5 April 1914. It was flown on O'Connell Street above the Imperial Hotel (Clery's) during the 1916 Easter Rising. It was believed to have been destroyed but was later discovered. It had been seized by a British officer who returned the flag to the Irish government in 1955. The flag was in a decrepit condition until it was restored with funding from the Irish Labour Party in 2013 and displayed at the National Museum of Ireland – Decorative Arts and History. It is believed that the banner was designed by the art teacher William H. Megahy. His original drawing featured a blue rather than a green field and was presented to the National Museum in 1954 by the playwright Seán O'Casey who was the secretary of the Irish Citizen Army before the Easter Rising. A statue of James Connolly with a bronze depiction of the Starry Plough that featured on the banner is located underneath the railway bridge on Beresford Place in Dublin. It was at this location that Connolly frequently addressed political and trade union rallies. The banner is still used today in the form of a flag by certain Irish socialist groups. | The banner features a green field bordered by a gilt fringe with a gold stylised representation of an agricultural plough that is superimposed by 7 silver stars forming the constellation Ursa Major, commonly known as 'the Plough'. |
| 1934–present | "In 1934, the largest trade union, the Irish Transport and General Workers Union (ITGWU), introduced a simplified version of the Starry Plough with a sky-blue field, resembling the Alaskan flag adopted 7 years earlier. It was adopted as the emblem of the Irish Labour movement, including the Irish Labour Party, although they eventually dropped it".[32] Today the flag is used by various Irish socialist, nationalist and republican groups. | The Starry Plough flag (An Camchéachta) features a light blue field with 7 five-pointed white stars forming the constellation Ursa Major, commonly known as 'the Plough'. |
| 1916 | On 24 April 1916, a flag with the inscription 'Irish Republic' was hoisted alongside the Irish tricolour over the General Post Office, Dublin during the 1916 Easter Rising as a proclamation of the Irish Republic. A photograph was taken of it flying on the south-eastern corner of the GPO by a guest staying in the Metropole Hotel. "It remained on the roof throughout the week, survived the bombardment and the fire which destroyed the G.P.O and was eventually removed by the troops after the insurgents' surrender, either on Sunday, 30 April or on the following day. A photograph taken at the time shows a group of soldiers holding it upside down at the base of Parnell monument in O'Connell Street. Thereafter, it was placed in the Imperial War Museum, London. It was presented by the British government to the Irish government on the fiftieth anniversary of the rising in 1966". | The flag features a green field with the inscription "Irish Republic" written in white and yellow (gold) letters in the form of Gaelic script. It measures 4 feet 3 inches by 5 feet 6 inches and is now on display at the National Museum of Ireland – Decorative Arts and History. |
