大猴胡桃（学名：Lecythis zabucajo）为玉蕊科玉蕊属下的一个种。

Lecythis zabucajo, sapucaia or paradise nut, is a large nut-producing tree occurring in the Guianas, Suriname, Venezuela, Ecuador, Honduras and Brazil, and which distribution range is much the same as that of the greater spear-nosed bat (Phyllostomus hastatus). Although not singling out Lecythis zabucajo, Jacques Huber noted in 1909 that fruit bats played the most important role in seed dispersal in Amazonian forests. The quality of its nuts led to the species' being introduced to numerous tropical countries, notably Trinidad, where it has flourished. The nuts are a valuable food resource and yield oil suitable for cooking and domestic use.
