Reask (Irish: Riasc) is a ruined early Monastic site located 1 km east of Baile an Fheirtéaraigh, County Kerry, Ireland. Although nothing remains of the buildings but low walls and a cross-slab standing stone which sits in the middle of the compound. Some of the artefacts found in the excavation at Reask, including some of the cross-inscribed stones, are on display in Músaem Chorca Dhuibhne, which is in the nearby village of Baile an Fheirtéaraigh. The site is a National Monument in state care.
