Lewis Evans (fl. 1574), was a Welsh controversialist, or polemicist, who was educated at Oxford and initially supportive of the Roman Catholic cause in England during the Reformation. He fled to Antwerp, where he translated a work from Latin. After being imprisoned in London upon his return, he reconciled to the established Church of England. He published books in 1568 and 1570 that virulently attacked the Roman Catholic Church.
