Treffgarne (Welsh: Trefgarn, or town of the rock) is a small village and parish in Pembrokeshire, south-west Wales.

A number of interesting minerals have been recorded including brookite crystals (titanium dioxide)[2] and possibly tin.

The current parish church, dedicated to St Michael, stands in a roughly, rectangular churchyard near the centre of the village.

Inside it are some ornate and colorful stained glass windows originally made in Munich and which were allegedly transported by horse and cart from St Giles' Cathedral in Edinburgh.

[11] Now bypassed by the modern A40 trunk road from Fishguard to Haverfordwest, the village originally sat on the turnpike that ran between these two towns.
