Old Radnor (Welsh: Pencraig) is a village and community in Powys, Wales.

The community includes Old Radnor and the villages of Yardro, Dolyhir, Burlingjobb, Evenjobb (Welsh: Einsiob), Kinnerton and Walton.

The 15th-century parish church, dedicated to Saint Stephen, is in Perpendicular Gothic style, and is noted for its early organ and organ case, early stained glass, fine rood screen and large pre-Norman font.

Adjacent to it are earthworks known as Old Radnor Castle, but it is unclear if this was ever in fact a fortification.
