Evan Evans (1731–1789) was a Welsh poet and antiquary.
Evans, son of Jenkin Evans, was born at [[Cynhawdref]], in the parish of [[Lledrod]], [[Cardiganshire]], on 20 May 1731. He received his education at the grammar school of Ystrad Meurig, under the scholar and poet, Edward Richard. Thence he removed to Oxford, and was entered at [[Merton College, Oxford|]] in 1751.
He conveyed a small freehold in Cardiganshire to his younger brother for 100l., in order to support himself at the university. After leaving Oxford without taking a degree he officiated as curate at [[Newick]], Sussex, at [[Towyn]], [[Merionethshire]], at [[Llanberis]] and Llanllechid, Carnarvonshire, and at [[Llanfair Talhaiarn]], [[Denbighshire]].
From an early age he cultivated poetry, and he was soon noticed by [[Lewis Morris (1701–1765)|]] the antiquary. He diligently applied himself to the study of , and employed his leisure time in transcribing ancient Welsh manuscripts, for which purpose he visited most of the libraries in Wales. At one time he received small annuities from Sir [[...|Watkin Williams Wynn]] and [[John Warren (bishop)|Dr. Warren]], when [[bishop of St David's]], to enable him to prosecute these researches. His first publication was entitled ‘Some Specimens of the Poetry of the Antient Welsh Bards, translated into English; with explanatory notes on the historical passages, and a short account of men and places mentioned by the Bards; in order to give the curious some idea of the tastes and sentiments of our Ancestors, and their manner of writing,’ London, 1764, 4to, reprinted at Llanidloes , 8vo. This work gained for its author a high reputation as an antiquary and a critic, and furnished Gray with matter for some of his most beautiful poetry. In it is included a Latin treatise by Evans, ‘De Bardis Dissertatio; in qua nonnulla quæ ad eorum antiquitatem et munus respiciunt, et ad præcipuos qui in Cambria floruerunt, breviter discutiuntur.’
