Grandson of Gruffydd Maelor I, and brother of Gruffydd Maelor II. When his father d. in 1236 Madog Fychan joined in the subsequent partition of Powys Fadog. He adopted the same attitude as Gruffydd Maelor I to the major political problems of the time; in 1245 he is found among the allies of Dafydd ap Llywelyn, and in 1258 he is on the side of Llywelyn ap Gruffydd. The fact that his surety for Tudur ab Ednyfed was accepted by Henry II in 1246 made his bond no less acceptable to Llywelyn ten years later. He died in December 1269, and may have been buried at Valle Crucis, of which he was a patron.
