Killone Abbey is a former nunnery located on the grounds of Newhall Estate in County Clare, Ireland. The abbey was founded in 1190 by Donal Mór O'Brien, King of Thomond and Munster, who placed there a sisterhood of the order of Saint Augustin. It was a prominent house of Canonesses Regular and one of the major female monastic institutions in Gaelic Ireland.
It became closely associated with the O'Brien dynasty, one of the leading Gaelic noble families in medieval Ireland, and many of its abbesses were drawn from their ranks. Among them was Slaney O'Brien, the daughter of Carbreagh, King of Thomond, who renounced her royal status and worldly possessions to take up the role of abbess.
