Oenocarpus is a genus of pinnate-leaved palms (Arecaceae) native to Trinidad, southern Central and tropical South America.

[3][4] With nine species and one natural hybrid, the genus is distributed from Costa Rica and Trinidad in the north to Brazil and Bolivia in the south.

These terms may also refer to the best-known member of this genus, O. bacaba, but more precise common names exist for that species.

The fruit of Oenocarpus palms are food for various animals, such as the green aracari (Pteroglossus viridis) for which O. bacaba fruit are a mainstay food.

They are also locally eaten by humans, and these palms are also used in folk medicine.
