Moor Abbey (Irish: An Múr)[1] is a ruined medieval Franciscan friary in Galbally, County Tipperary, Ireland, on the banks of the River Aherlow.

Located on the north bank of the River Aherlow, Moor Abbey was established by Donnchadh Cairprech Ó Briain, King of Thomond 1210–42.

In 1541 the friary was dissolved and later became the property of John, brother of James FitzGerald, 14th Earl of Desmond.

James Butler, Vicar-General of Cashel & Emly diocese and the abbey fell into ruin.

[5] The ruined church consists of a nave and chancel, separated by a tall bell-tower with sedilia.
