Kilmacrehy, Civil parish in West Clare Municipal District, Ireland

Kilmacrehy is a civil parish on the western coast of Clare with extensive pasture and farmland that reaches toward Liscannor Bay. Two ruined medieval castles stand within its boundaries, one in the Dough area and another near Liscannor.

The parish church in Laghcloon townland, east of Liscannor, has written records going back only to the 14th century, though its founding is attributed to Saint Mac Creiche. In 1588 ships of the Spanish Armada were wrecked on the parish shore. By 1831 the population was 3,343, rising to 4,264 in 673 houses by 1841.

The parish is named after Saint Mac Creiche, a possibly legendary figure who founded several churches in Clare; Kilmacrehy is the only church bearing his name. In Liscannor Bay, rocks called MacCreiche's Bed lie before the strand, with MacCreiche's Well about 200 metres northwest. Near Birchfield, a holy well dedicated to Saint Bridget was visited on the eve of the first Sunday of August for cures.

The parish church ruins stand in Laghcloon townland, east of Liscannor, and the two ruined castles lie at Dough and Liscannor. MacCreiche's Bed rocks and MacCreiche's Well sit about 200 metres apart in the bay before the strand. The Cliffs of Moher run northeast from Hag's Head to O'Brien's Tower, about 180 metres above the sea.

The parish church at Laghcloon is the only one named for Saint Mac Creiche, a possibly legendary founder of churches in Clare. In Liscannor Bay, rocks called MacCreiche's Bed lie before the strand, with MacCreiche's Well about 200 metres to the northwest.
