English: The rambutan (;taxonomic name: Nephelium lappaceum) is a medium-sized tropical tree in the family Sapindaceae. The name also refers to the edible fruit produced by this tree. The rambutan is native to the Malay-Indonesian region, and other regions of tropical Southeast Asia. It is closely related to several other edible tropical fruits including the lychee, longan, and mamoncillo.

The name 'rambutan' is derived from the Malay-Indonesian languages word for rambut or "hair", a reference to the numerous hairy protuberances of the fruit, together with the noun-building suffix -an. In Vietnam, it is called chôm chôm (meaning "messy hair") due to the spines covering the fruit's skin

The fruit is a round to oval single-seeded berry, 3–6 cm (rarely to 8 cm) long and 3–4 cm broad, borne in a loose pendant cluster of 10–20 together. The leathery skin is reddish (rarely orange or yellow), and covered with fleshy pliable spines.. The fruit flesh, which is actually the aril, is translucent, whitish or very pale pink, with a sweet, mildly acidic flavor very reminiscent of grapes.
