Carambola, or star fruit, is the fruit of 'Averrhoa carambola', a species of tree native to tropical Southeast Asia. The fruit is commonly consumed throughout Southeast Asia, the South Pacific, Micronesia, and parts of East Asia. The tree is cultivated throughout tropical areas.

The fruit has distinctive ridges running down its sides (usually five but can occasionally vary); when cut in cross-section, it resembles a star, hence its name. The entire fruit is edible and is usually eaten out of hand. They may also be used in cooking and can be made into relishes, preserves, and juice drinks.

The carambola tree has a short trunk with many branches, reaching up to 30 feet (9.1 m) in height. Its deciduous leaves are 6–10 inches (15–25 cm) long, with 5 to 11 ovate leaflets medium-green in color. Flowers are lilac in color, with purple streaks, and are about 0.25 inches (6.4 mm) wide.
