"The Poet and the Grey Friar" (Welsh: Y Bardd a'r Brawd Llwyd) is a satirical poem in the form of a traethodl by the 14th-century Welsh poet Dafydd ap Gwilym, widely seen as the greatest of the Welsh-language poets. In it he relates an imaginary conversation with a Franciscan friar in which, rejecting the ascetic philosophy of the friar, he sets out a defence of love, poetry and the worldly life. It was included in The Oxford Book of Welsh Verse and The Penguin Book of Welsh Verse.
