Robert Hues (1553–1632) was an English geographer and mathematician best known for his work on globes and navigation. Educated at St. Mary Hall, Oxford, he gained prominence through his treatise Tractatus de Globis et eorum Usu (1594), which provided a systematic explanation of the use of terrestrial and celestial globes for navigation and astronomy. Based on firsthand observations during voyages with Thomas Cavendish and Walter Raleigh, Hues’ work was influential in advancing practical navigation techniques. His Tractatus was widely used by navigators and scholars, contributing to the broader understanding of globes as essential tools for early modern cartography and exploration.
