# List of monastic houses in Wales

List of monastic houses in Wales is a catalogue of abbeys, priories, friaries and other monastic religious houses in Wales.

The numerous monastic hospitals per se are not included here unless at some time the foundation had, or was purported to have, the status or function of an abbey, priory, friary, preceptory or commandery.
The geographical co-ordinates provided are sourced from details provided by Ordnance Survey publications.
