Lissycasey (Irish: Lios Uí Chathasaigh, meaning 'ringfort of the Caseys') is a village in County Clare, Ireland.

The area stretches east–west from Caherea to Crown and north–south from Frure North to Cloncolman.

The box was opened by the police and found it was full of gold coins of an ancient date.
