Powys Fadog (English: Lower Powys or literally Madog's Powys) was the northern portion of the former princely realm of Powys. The princes of Powys Fadog would build their royal seat at Castell Dinas Brân, and their religious center at Valle Crucis Abbey. Some of its lordships included those of Maelor, Mochnant, Glyndyfrdwy, Yale, and Bromfield and Yale. Following the division of Powys, their cousin branch, the princes of Powys Wenwynwyn, would build Powis Castle.
The principality's first prince was Gruffydd Maelor I, and its last sovereign prince was Madog II ap Gruffydd, following the Conquest of Wales by king Edward Longshanks.
