Oenocarpus is a genus of pinnate-leaved palms (Arecaceae) native to Trinidad, southern Central and tropical South America. 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. Common names in their native range are bacaba in Brazil, and palma milpesos (or just milpesos) in Spanish-speaking countries. These terms may also refer to the most well-known member of this genus, O. bacaba, but more precise common names exist for that species.
