Presteigne is a town and community in Powys, Wales. It was the county town of the historic county of Radnorshire. Despite lying on a minor B road the town has, in common with several other towns close to the Wales-England border, assumed the motto, "Gateway to Wales".
The town sits on the south bank of the River Lugg, which forms the England–Wales border as it passes the town — the border effectively wraps around three sides of the town (north, east and south). Nearby towns are Kington to the south and Knighton to the north, and surrounding villages include Norton and Stapleton. The town falls within the Diocese of Hereford.
