Madog ap Llywelyn (died after 1312) was the leader of the Welsh revolt of 1294–95 against English rule in Wales. The revolt was surpassed in longevity only by the revolt of Owain Glyndŵr in the 15th century. Madog belonged to a junior branch of the House of Aberffraw and was a distant relation of Llywelyn ap Gruffudd, the last recognised native Prince of Wales. During his revolt, Madog issued a land grant in which he used the title "Prince of Wales".
