The 1981 Irish hunger strike was the culmination of a five-year protest during the Troubles by Irish republican prisoners in Northern Ireland. The protest began as the blanket protest in 1976, when the British government withdrew Special Category Status for convicted paramilitary prisoners. In 1978, the dispute escalated into the dirty protest, where prisoners refused to leave their cells to wash and covered the walls of their cells with excrement. In 1980, seven prisoners participated in the first hunger strike, which ended after 53 days.

The blanket protest was part of a five-year protest during the Troubles by Provisional Irish Republican Army (IRA) and Irish National Liberation Army (INLA) prisoners held in the Maze prison in Northern Ireland. The republican prisoners' status as political prisoners, known as Special Category Status, had begun to be phased out in 1976. Among other things, this meant that they would now be required to wear prison uniforms like ordinary convicts. The prisoners refused to accept the administrative designation of ordinary criminals, and refused to wear the prison uniform.
