Llanwrin (pronunciationⓘ) is a small village in the valley of the Afon Dyfi in Powys, Wales, about two miles north-east of Machynlleth.

Historically, it was in the county of Montgomeryshire (Welsh: Sir Drefaldwyn).

The village is named after its church, dedicated to St. Gwrin, which dates from late medieval times and was last restored in 1864.

[1] The nearby historically significant house of Mathafarn dates back to at least 1485.

Once a thriving community with its own blacksmith, pub and village shop – all long since closed – in recent years the village has been a collection of houses stretched along the B4404 road.
