There is evidence of settlement in the area for at least 1000 years. There may have been an abbey in the area around 700AD. The Augustinian abbey of St Mary's was built in the 11th century. Its ruins contain the tomb of O'Cahan, laid to rest in 1385. A thicket of thorn bushes hung with rags conceals a bullaun stone, visited for wart cures. Between the 12th and 17th centuries the area was ruled by the Ó Catháin clan, one of the most influential clans in Ulster and respected throughout Ireland. In the early 17th century they built Dungiven Castle, which - having been substantially rebuilt in the 19th century - remains today as a restaurant and guesthouse. The world-famous song Danny Boy is taken from a melody composed by the Ó Catháin bard, Ruairí Dall Ó Catháin. The original version concerns the passing of the Chief Cooey-na-Gall, whose death brought an end to the long line of O'Cahan chiefs. The town sprang up around Dungiven Castle and the Church of Ireland, later spreading westwards along Chapel Road and Main Street towards the bridging point on the River Roe. Because of the River Roe's flood plain and the line of a proposed by-pass, housing development has been mostly to the east and north of the town. It is an important service centre for the surrounding rural hinterland; offering educational, health, commercial, social, community and recreational facilities.
During The Troubles in Northern Ireland, seven people were killed in or near Dungiven in connection with the conflict, six of whom were members of the security forces. The one civilian, Francis McCloskey, was found beaten to death in disputed circumstances during street riots, in which the police were called to respond. He has sometimes been deemed as the first person killed in the last installment of the Troubles.
