José de Acosta was a sixteenth-century Spanish Jesuit missionary and naturalist in Latin America.

Aside from his publication of the proceedings of the provincial councils of 1567 and 1583, and several works of exclusively theological import, Acosta is best known as the writer of De Natura Novi Orbis, De promulgatione Evangelii apud Barbaros, sive De Procuranda Indorum salute and above all, the Historia natural y moral de las Indias . The latter was published at Seville in 1590, and was soon after its publication translated into various languages. It established the reputation of Acosta, as this was one of the very first detailed and realistic descriptions of the New World. In a form more concise than that employed by his predecessors, Francisco Lopez de Gómara and Oviedo, he treated the natural and philosophic history of the New World from a broader point of view. In it, more than a century before other Europeans learned of the Bering Strait, Acosta hypothesized that Latin America's indigenous peoples had migrated from Asia. He also divided them into three barbarian categories. The Historia also described Inca and Aztec customs and history, as well as other information such as winds and tides, lakes, rivers, plants, animals, and mineral resources in the New World.
