Doolin (Irish: Dúlainn) is a coastal village in County Clare, Ireland, on the Atlantic coast. It borders the spa town of Lisdoonvarna. It is a noted centre of traditional Irish music, which is played nightly in its pubs, making it a popular tourist destination. There are numerous nearby archaeological sites, many dating to the Iron Age and earlier. Doonagore Castle and Ballinalacken Castle are also in the area.
Doolin is one of three places (Galway and the village of Rossaveal on the northwest shore of Galway Bay are the others) with ferry services to the Aran Islands, which are visible from the town. Doolin is also close to the Cliffs of Moher, and a bus service between Galway and Limerick/Ennis calls at both Doolin and the cliffs in each direction. The area is at the south-western corner of the Burren region. Recently, a ferry service has begun bringing tourists from Doolin Pier to the base of the Cliffs of Moher.
The Aille River runs from the hills of the Burren down past Doolin to meet the sea. The small Crab Island is a short distance out from Doolin Harbor, barren except for the remains of a 19th-century stone constabulary outpost.
