Northern Ireland comprises a patchwork of communities whose national loyalties are represented in some areas by flags flown from flagpoles or lamp posts. The Union Jack and the former Northern Ireland flag are flown in some loyalist areas, and the Tricolour, adopted by republicans as the flag of Ireland in 1916,^[53] is flown in some republican areas. Even kerbstones in some areas are painted red-white-blue or green-white-orange, depending on whether local people express unionist/loyalist or nationalist/republican sympathies.^[54]

The official flag is that of the state having sovereignty over the territory, i.e. the Union Flag.^[55] The former Northern Ireland flag, also known as the "Ulster Banner" or "Red Hand Flag", is a banner derived from the coat of arms of the Government of Northern Ireland until 1972. Since 1972, it has had no official status. The Union Flag and the Ulster Banner are used exclusively by unionists. UK flags policy states that in Northern Ireland, "The Ulster flag and the Cross of St Patrick have no official status and, under the Flags Regulations, are not permitted to be flown from Government Buildings."^[56][57]

The Irish Rugby Football Union and the Church of Ireland have used the Saint Patrick's Saltire or "Cross of St Patrick". This red saltire on a white field was used to represent Ireland in the flag of the United Kingdom. It is still used by some British army regiments. Foreign flags are also found, such as the Palestinian flags in some Nationalist areas and Israeli flags in some Unionist areas.

The United Kingdom national anthem of "God Save the Queen" is often played at state events in Northern Ireland. At the Commonwealth Games and some other sporting events, the Northern Ireland team uses the Ulster Banner as its flag—notwithstanding its lack of official status—and the Londonderry Air (usually set to lyrics as Danny Boy), which also has no official status, as its national anthem.^[58][59] The Northern Ireland football team also uses the Ulster Banner as its flag but uses "God Save The Queen" as its national anthem.^[60] Major Gaelic Athletic Association matches are opened by the Irish national anthem, "Amhrán na bhFiann (The Soldier's Song)", which is also used by most other all-Ireland sporting organisations.^[61] Since 1995, the Ireland rugby union team has used a specially commissioned song, "Ireland's Call" as the team's anthem. The Irish national anthem is also played at Dublin home matches, being the anthem of the host country.^[62]

Northern Irish murals have become well-known features of Northern Ireland, depicting past and present divisions, both also documenting peace and cultural diversity. Almost 2,000 murals have been documented in Northern Ireland since the 1970s.
