TRIGAND, Jacques Nicolas Bellin de (tree-gahng), French geographer, born in Paris in 1703; died in Versailles, 21 March, 1772. He entered the employment of the navy department, and was instructed to make charts of all the oceans and seas. His "Neptune Francais" (Paris, 1753) contains charts of the coast of France, and his "Hydrographic Francaise" (1756) contains eighty charts of the coast of both Americas, Asia, and Africa.

He prepared also all the charts that are in Abbe Prevost's "Histoire generale des voyages," and contributed to the Academy of sciences several "Memoires sur les cotes de l'Amerique Septentrionale," which were collected and printed (Paris, 1755). His works include also "Essais geographiques sur les iles Britanniques" (1763);" Essai sur la Guyane" (1757) ; "Geographie des Antilles" (1765) ; and "Essai sur File de Saint Domingue" (1766).
