Jacques Nicolas Bellin (1703 – 21 March 1772) was a French hydrographer, geographer, and member of the French intellectual group called the philosophes.
Bellin was born in Paris. He was hydrographer of France's hydrographic office, member of the Académie de Marine and of the Royal Society of London. Over a 50-year career, he produced many maps of particular interest to the Ministère de la Marine. His maps of Canada and of French territories in North America (New France, Acadia, Louisiana) are particularly valuable. He died at Versailles.
