Cadwaladr Cesail (1614–1626)[1] was a Welsh poet.
Cesail is believed to have lived at Y Gesail Gyfarch, in Caernarfonshire. He wrote cywyddau and englynion to praise or eulogize members of prominent families, such as the Bodwrda family of Caernarvonshire . It is thought at least 27 of Cesail's cywydd poems and nine of his englyn poems may still survive.[2]
