Thomas Bowen (b. c. 1733 - March 1790) was a Welsh engraver of maps and charts. He was the son of Emanuel Bowen (1693/4–1767), under whom he had apprenticed. His work was printed with his father's, as well as other publishers throughout the latter half of the eighteenth century. He married Alice Downes on December 25, 1768. He appears even thento have not been successful, and more than once found himself a debtor. He was imprisoned for debt in 1761, and he met his death in 1790 in Clerkenwell workhouse.
