The açaí palm, Euterpe oleracea, is a species of palm tree (Arecaceae) cultivated for its fruit, hearts of palm, leaves, and trunk wood. Global demand for the fruit has expanded rapidly in the 21st century, and the tree is cultivated for that purpose primarily.

Heart of palm is a vegetable harvested from the inner core and growing bud of certain palm trees, most notably the coconut, juçara, açaí palm, palmetto, and peach palm. Harvesting of many uncultivated or wild single-stemmed palms results in palm tree death. However, other palm species are clonal or multi-stemmed plants, and moderate harvesting will not kill the entire clonal palm. Heart of palm may be eaten on its own, and often it is eaten in a salad.
