Aleurites moluccanus (or moluccana), the candlenut, is a flowering tree in the spurge family, Euphorbiaceae, also known as candleberry, Indian walnut, kemiri, varnish tree, nuez de la India, buah keras or kukui nut tree.

Its native range is impossible to establish precisely because of early spread by humans, and the tree is now distributed throughout the New and Old World tropics. It grows to a height of 15–25 m (49–82 ft), with wide spreading or pendulous branches. The leaves are pale green, simple and ovate, or trilobed or rarely five-lobed, with an acute apex, 10–20 cm (3.9–7.9 in) long. The nut is round, 4–6 cm (1.6–2.4 in) in diameter; the seed inside has a very hard seed coat and a high oil content, which allows its use as a candle (see below), hence its name.
