Ardfert Abbey (Irish: Mainistir Ard Fhearta), also known as Ardfert Friary, is a ruined medieval Franciscan friary and National Monument in Ardfert, County Kerry, Ireland. It is thought to be built on the site of an early Christian monastic site founded by Brendan the Navigator. The present remains date from the mid-thirteenth century, with the residential tower being added in the 15th century. The friary was dissolved in 1584.
