Lonchocarpus utilis (cubé, (common) lancepod or barbasco) is a species of shrub in the family Fabaceae.

It is native to the tropical forests of Peru, as well as of Brazil and Guyana, growing from 100–1,800 m (330–5,910 ft) above sea level.

Cubé resin, the root extract from cubé and from barbasco (Lonchocarpus urucu), is used as a commercial insecticide and piscicide (fish poison).

Although "organic" (produced by nature) rotenone is no longer considered an environmentally safe chemical.

Cubé is toxic to insects, fish, and other pets.
