d'Heulland, Guillaume (c. 17?? - 1770) was a prolific French engraver active in Paris during the mid-18th century; his known work spans from 1731 to 1766. Most of his work focuses on maps, scientific diagrams, and architectural plans. He engraved nautical charts for the French Royal Navy; he engravred many maps and charts for Bellin, as well as for Charlevoix, Cassini, and Prevost. He appears to have engraved most, if not all of the charts for D'Après de Mannevillette's 1745 Neptune Oriental. He is perhaps best known for his 1756 Plan of Paris. The engraver Choffard was one of his apprentices.
