Claudy (from Irish: Clóidigh, meaning "the one who washes/the strong-flowing one") is a village and townland (of 1,154 acres) in County Londonderry, Northern Ireland. It lies in the Faughan Valley, 6 miles (9.7 km) southeast of Derry, where the River Glenrandal joins the River Faughan. It is situated in the civil parish of Cumber Upper and the historic barony of Tirkeeran.
Claudy had a population of 1,336 people in the 2011 Census. It has two primary schools, two churches and a college named St Patrick's and St. Brigid's College.
Claudy suffered 13 fatalities during The Troubles, amounting to one per cent of its 2001 population. The death rate in Belfast, by comparison, was equivalent to just over half a percent, and that in Derry a quarter of a percent. Nine of the 13 people killed died in the Claudy bombing in which three car bombs exploded on Main Street.
