John Lodge Cowley (1719 to 1797) was an English cartographer, geologist and mathematician. He was professor of mathematics at the Royal Military Academy, Woolwich, for some years between 1761 and 1773 and was elected a Fellow of the Royal Society in April 1768. Best known as a map maker who styled himself Cartographer Royal to King George II, he published miniature maps of the English counties, often engraved by Emanuel Bowen and produced with the publisher Robert Dodsley, as well as a question and answer introduction to geography. In mathematics he wrote introductory works on solid geometry with fold-up figures, among them Geometry Made Easy of 1752, An Appendix to Euclid's Elements of 1758 and The Theory of Perspective Demonstrated of 1765, and he taught geometry to subscribers of the St Martin's Lane Academy.
