Rhys Mechyll (died 1244) was a Welsh prince of the House of Dinefwr, ruler of part of the kingdom of Deheubarth in southern Wales from 1234 to 1244. He was a son of Rhys Gryg (died 1234) ("Rhys the Hoarse"), son of Rhys ap Gruffydd (1132–1197),[1] "The Lord Rhys", ruler of the kingdom of Deheubarth.


He married Matilda de Braose (died 1248) who betrayed the dynasty's chief castle of Carreg Cennen to the Anglo-Normans in 1248, against the interests of her son Rhys. A Welsh chronicle, the Brut y Tywysogyon, records under the year 1248: "Rhys Fychan ap Rhys Mechyll regained the castle of Carreg Cennen, which his mother had treacherously placed in the power of the French, out of enmity for her son."[2]


He had a son Rhys Fychan (i.e. "The Younger") ap Rhys Mechyll,[1] and a daughter Gwenllian, his eventual heiress who married Gilbert Talbot (died 1274), grandfather of Gilbert Talbot, 1st Baron Talbot (died 1345/6),[3] to whom passed the ancient armorials of the House of Dinefwr, assumed as arms of alliance to a great princess in place of his own paternal arms.[4]
