The Priory and Parish Church of Saint Mary is in Beddgelert, in the Snowdonia area of Gwynedd, Wales.

An Augustinian priory was founded there in the 13th century and in the Middle Ages it grew substantially thanks to the support of important Welsh nobles including Prince Llewelyn.

As of the early 16th century it was Sir John Wynn (ancestor of the Barons Newborough who owned the priory in addition to Bardsey Island.

[2] In the 16th century, as part of the dissolution of the monasteries, the priory was closed in October 1535[3] and became a simple parish church.

Remnants of the church's medieval past include transept arches and some of the stonework around the lancet windows.
