The Burren (Irish: Boireann, meaning "great rock", Boirinn, the dative form, is the modern form used by the Ordnance Survey) is a karst-landscape region or alvar in northwest County Clare, in Ireland. It is one of the largest karst landscapes in Europe. The region measures approximately 250 square kilometres and is enclosed roughly within the circle made by the villages Ballyvaughan, Kinvara, Tubber, Corofin, Kilfenora and Lisdoonvarna. It is bounded by the Atlantic and Galway Bay on the west and north, respectively.
A small portion of the Burren has been designated as Burren National Park. It is one of only six National Parks in Ireland and the smallest in size (15 km²).
