Tievenadarragh (from Irish Taobh an Doire, meaning "hillside of the oak wood") is a townland at Loughinisland, County Down, Northern Ireland. The townland contains the Loughinisland Churches, the remains of three ruined churches dating from the 13th to the 17th centuries. They are situated in a large graveyard on an island in Loughinisland Lake, now reached by a causeway.
