Ballyallaban ringfort (Irish: Baile Albóin) or sometimes An Rath ("The Rath") is an earthen ringfort south of Ballyvaughan in the Burren area, in County Clare, Ireland.

The fort lies right next to the R480 road between the village of Ballyvaughan and Leamaneh Castle.

It is located in the townland of Ballyallaban, in the civil parish of Rathborney.

The ramparts were built with the earth dug out of the moat, which still fills with water after rain.
