Emanuel Bowen (1694?-1767) was a British engraver and print seller. He was most well-known for his atlases and county maps. Although he died in poverty, he was widely acknowledged for his expertise and was appointed as mapmaker to both George II of England and Louis XV of France. His business was carried on by his son, Thomas Bowen. He also trained many apprentices, two of whom became prominent mapmakers, Thomas Kitchin and Thomas Jeffreys.
