The Real Irish Republican Army is a paramilitary group founded by former members of the Provisional IRA before the signing of the 1998 Good Friday (Belfast) Agreement. The Real IRA is opposed to the Provisional IRA's 1997 cease-fire and acquiescence in the accord. It originally attracted disaffected IRA member from the Republican stronghold of South Armagh, and some member in Derry. Its first leader was Michael McKevitt, a former quarter master general of the provisional IRA, but he has since been imprisoned in charges of directing terrorism. Shortly after formation, the Real IRA began attacks in similar nature to those conducted by the Provisional IRA prior to its ceasefire. However, it lacked a significant base, and was heavily infiltrated with informers, leading to a series of high profile arrests and seizures by British and Irish police in the first half of 1998. Despite this, the Real IRA succeded in bombing Omagh town Center on August 14 1998, killing 29 people. Omagh bombing. This caused a major outcry in Ireland. Many of its members abondoned it, and British and Irish police co-operated on an unprecedented scale to destroy the movement. It called a ceasefire in the winter of 1998, but this lasted less then two years, when they conducted a number of relatively minor attacks on the island of Great Britain, including a taxi-bomb attack on the BBC Television Centre in West London, and a rocket propelled grenade attack on the headquarters of MI6. Since then, it has become weaker and weaker. Infiltration has continued, and the movement has been unable to conduct a noticeable bomb attack. In the fall of 2003, its imprisoned leaders called for an unconditional ceasefire, citing alledged missue of funds and the futile nature of their resistence to the British presence in Ireland. In recent times, the Real IRA has continued to be a thorn in the side of both the British and Irish authorites. December 2004 saw 15 fire bomb attacks against premises in Belfast, attributed to the breakaway faction. Many see this as a sign of growing support for the group, in light of failed attempts to rescue the Belfast Peace accord.

The Real IRA is distinct from the Continuity IRA, another Provisional IRA splinter group, founded in 1986. The 32 County Sovereignty Movement is perceived to be the political wing of the Real IRA.
