Gaetano Osculati (1808-1894) was an Italian naturalist. He was born in Biassono, Lombardy, 29 November 1808 At an early age he devoted himself to the study of the natural sciences, and in 1830-'1 he visited Greece, Egypt, Asia Minor, and other provinces of the Turkish empire. He embarked for South America in 1834, traversed the greater part of that continent, and in 1836 returned to Europe by the way of Cape Horn.
In 1841 he visited Arabia, Armenia, Persia, and the coast of Malabar, and in 1846 he visited this country. After passing hurriedly through Canada, the United States, the Antilles, and Venezuela, he went to Quito, and thence started on an expedition to the Napo, a tributary of the Amazon.
After several days' march he was abandoned by his Indian guides, but he succeeded in reaching the Napo alone, after a journey across a wide expanse of unsettled country and through trackless forests. He suffered for food, and during two weeks subsisted on palm-leaves and a single kind of fruit. In 1848 he returned to Europe with a rich collection. He published "Ezplorazione delle regioni equatoriali lungo il Napo" (Milan, 1854). He died in Milan, 14 March 1894
