Clonderalaw (Irish: Cluain idir Dhá Lá)[1] is an historical barony in County Clare, Ireland.

While baronies have been administratively obsolete since 1898, they continue to be used in some land registration contexts and in planning permissions.

[2] Its east coast is very frequently but not boldly indented, and is flanked by the numerous green and beauteous isles of the Fergus; and its south coast is very sweepingly varied in outline by the projection of the Clonderalaw peninsula, and the deep incision on this peninsula’s west side of Clonderalaw bay.

The surface of the barony, excepting a belt of rich, beautiful low ground along the coast, consists largely of bog and moorish mountain; but, in consequence of abundance of lime being procurable with little trouble and at small expense, it is highly improvable.

It contains old castles of Clonderalaw, Donogorogue, Redgap, Colesmanstown, Dangan, Crownaghan, Horse-Island, and Cahirmurphy.
