Armagh is a city in Northern Ireland, the county town of County Armagh. Armagh was granted a Royal Charter by Queen Elizabeth II in 1994, and City status was officially re-conferred in 1995. Armagh is the least populated city in Northern Ireland.

Armagh Prison in Northern Ireland was the scene of a protest by female Irish Republican prisoners demanding political status, although the numbers involved were much smaller than in the Maze (also known as Long Kesh) men's prison. As all women prisoners in Northern Ireland already had the right to wear their own clothes, they did not stage any sort of blanket protest, but in their case the dirty protest included smearing their menstrual blood on the cell walls. Three women in Armagh took part in the 1980 hunger strike, one of whom, Mairéad Farrell, was shot by the SAS in Gibraltar in 1988, but none took part in the 1981 Irish Hunger Strike.

Armagh is one of the six counties comprising Northern Ireland.
