Original Umbro football shirt Northern Ireland 1990/92

The Northern Ireland national football team represents Northern Ireland in international association football. From 1882 to 1950, all of Ireland was represented by a single side, the Ireland national football team, organised by the Irish Football Association (IFA). In 1921, the jurisdiction of the IFA was reduced to Northern Ireland following the secession of clubs in the soon-to-be Irish Free State, although its team remained the national team for all of Ireland until 1950, and used the name Ireland until the 1970s.The Football Association of Ireland (FAI) organises the separate Republic of Ireland national football team.

Although part of the United Kingdom, Northern Ireland has always had a representative side that plays in major professional tournaments – whether alongside the rest of Ireland pre-1922 or as its own entity – though not in the Olympic Games, as the International Olympic Committee (IOC) has always recognised United Kingdom representative sides.

Northern Ireland has competed in three FIFA World Cups, reaching the quarter-final stage in the 1958 and 1982 tournaments. Northern Ireland held the accolade of being the smallest nation to qualify for a World Cup Finals from their first appearance in 1958 until 2006, when Trinidad and Tobago qualified for the 2006 World Cup. At UEFA Euro 2016, the team made its first appearance at the European tournament and reached the round of 16.
