Bernhardt Jungmann (1671 - 1747) was a German botanist who was a professor in Germany and visited America.
In 1712 he went to Leiden, and was sent by the Dutch government on a scientific mission to America.
He visited successively Canada, New England, Mexico, Cuba, and Puerto Rico 1715–1724, and lived several years in Saint Eustache and Saint Lucia, returning in 1727 to Leiden.
He died there of yellow fever a few days before his intended departure for Europe.
He also contributed papers to the academies of sciences of Paris and Vienna, on Mexican antiquities, which were inserted in the Recueil des mémoires de l'académie, and reprinted in the Blätter für literarische Unterhaltung (Brunswick, 1837).
