Tudur Aled (c. 1465–1525) was a late medieval Welsh poet, born in Llansannan, Denbighshire.
He is regarded as one of the finest poets of his period and was a master of cynghanedd.
Tudur was himself a nobleman and one of the greatest of the Beirdd yr Uchelwyr (Poets of the Nobility). His most important patrons were the Salisbury family of Dyffryn Clwyd. He was one of the instigators of the Caerwys eisteddfod of 1523. In his final illness he took the habit of Order of St. Francis and died in Carmarthen, where he was buried in the Brothers' Court. At his death the elegies his fellow poets wrote in his memory attested to his greatness as a poet. He was renowned as a praise poet of both secular and religious noblemen, and also reflects the changes at the beginning of the sixteenth century which were threatening the future of the bardic system.
