The Greysteel massacre was a mass shooting that happened on the evening of 30 October 1993 in Greysteel, County Londonderry, Northern Ireland. Three members of the Ulster Defence Association (UDA), a loyalist paramilitary group, attacked a crowded pub with firearms, killing eight civilians and wounding thirteen. The group claimed responsibility using their covername "Ulster Freedom Fighters" and said that the pub was targeted because it was in an Irish nationalist and Catholic area.

On 23 October 1993, a Provisional Irish Republican Army (IRA) bomb prematurely exploded in a fish shop on Shankill Road, west Belfast. Eight Protestant civilians, a UDA member and one of the IRA bombers were killed. The IRA's intended target was a meeting of UDA leaders including brigadier Johnny Adair, which was to take place above the shop. Unbeknownst to the IRA, the meeting had been rescheduled. Shortly after two IRA members, Thomas Begley and Sean Kelly, entered the shop dressed as deliverymen and carrying the time bomb under a tray, it exploded accidentally, killing Begley instantly, along with the nine others inside the shop at the time. This became known as the Shankill Road bombing.

Greysteel or Gresteel is a village in County Londonderry, Northern Ireland. It lies 9 miles (14 km) to the east of Derry and 7 miles (11 km) to the west of Limavady on the main A2 coast road between Limavady and Derry, overlooking Lough Foyle. It is designated as a Large Village and in the 2001 Census it had a population of 1,229 people, an increase of almost 20% compared to 1991.

The village lies mostly within the townlands of Gresteel More and Gresteel Beg. Historically these townlands were called Craisteele or Glasteele. The origin of Craisteele is uncertain, but Glasteele may be from Irish: Glas-stiall meaning "green strip". The Placenames Database of Ireland lists Glas-stiall as the Irish name of the village.

The Greysteel massacre took place on 30 October 1993 when three members of the Ulster Freedom Fighters attacked a crowded bar with firearms, killing eight people. This was the only fatal incident of "the Troubles" to occur in or near Greysteel.

Until relatively recently, the village had limited local facilities, with a modest sized general shop, a few other retail units, a primary school, a Gaelic club with playing fields and several public houses. However, the recent construction of the Vale Centre, developed by Greysteel Community Enterprise, a local development group, includes a range of commercial/industrial units and playing fields and has improved the situation. A range of activities is available in the Centre, including an after school club, adult learning centre and sports facilities. Commercial facilities in the Centre, provide an opportunity for small business start-ups and a further 10 units are currently under construction. The village has grown considerably during the Post War period, mostly through new public sector housing up to the 1970s, and subsequently through considerable private housing development.
