The Barony of Moyarta is a geographical division of County Clare, Ireland, that in turn is divided into civil parishes.

Baronies were created after the Norman invasion of Ireland as divisions of counties and were used the administration of justice and the raising of revenue.

In many cases, a barony corresponds to an earlier Gaelic túath which had submitted to the Crown.

The Barony of Moyarta lies on a peninsula extending between the Atlantic Ocean to the west and the Shannon Estuary to the south, terminating at the point of Loop Head.

The main settlements are Kilrush, Cross, Kilbaha, Kilballyhone, Kiltrellig, Ross, Tullig, Kilkee, Cooraclare, Bellina, Carrigaholt, Doonaha, and Lisheen.
