Ellis Owen (31 March 1789 – 27 January 1868) was a Welsh antiquarian and poet.

He went to school at Penmorfa, and was afterwards sent to Shrewsbury; on returning home he settled at Cefynmeusydd, and on his father's death took charge of the farm.

He spent the rest of his life at Cefnymeusydd as a prosperous farmer of much local influence, and died there on 27 January 1868.

He was chiefly remarkable as a writer of ‘englynion’ (stanzas), as a local antiquary and genealogist, and as the friend and tutor of the young poets of the district.

Four days before his death he had been elected a fellow of the Society of Antiquaries.
