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'Apr├Ęs 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.
