The Northern Ireland peace process includes the events leading up to the 1994 Provisional Irish Republican Army (IRA) ceasefire, the end of most of the violence of the Troubles, the Good Friday Agreement of 1998, and subsequent political developments.

The Troubles were an ethno-nationalist conflict in Northern Ireland that lasted for about 30 years from the late 1960s to 1998. Also known internationally as the Northern Ireland conflict, it is sometimes described as an "irregular war" or "low-level war". The conflict began in the late 1960s and is usually deemed to have ended with the Good Friday Agreement of 1998. Although the Troubles mostly took place in Northern Ireland, at times violence spilled over into parts of the Republic of Ireland, England, and mainland Europe.
