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.

In this article, alien houses are included, as are smaller establishments such as cells and notable monastic granges (particularly those with resident monks), and also camerae of the military orders of monks (Templars and Hospitallers).

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.

In order to assist in text-searching such alternatives in name or spelling have been provided.

Locations with names in italics indicate probable duplication (misidentification with another location)or non-existent foundations (either erroneous reference or proposed foundation never implemented).
