Guaraná (/ɡwəˈrɑːnə/ from the Portuguese guaraná [ɡʷaɾɐˈna]; Paullinia cupana, syns. P. crysan, P. sorbilis) is a climbing plant in the family Sapindaceae, native to the Amazon basin and especially common in Brazil. Guaraná has large leaves and clusters of flowers, and is best known for the seeds from its fruits, which are about the size of a coffee bean.

As a dietary supplement or herb, guaraná seed is an effective stimulant: it contains about twice the concentration of caffeine found in coffee beans (about 2–8% caffeine in guarana seeds, compared to about 1–3% for coffee beans). The additive has gained notoriety for being used in energy drinks. As with other plants producing caffeine, the high concentration of caffeine is a defensive toxin that repels herbivores from the berry and its seeds.

The colour of the fruit ranges from brown to red and it contains black seeds that are partly covered by white arils. The colour contrast when the fruit is split open has been compared with the appearance of eyeballs and has become the basis of an origin myth among the Sateré-Mawé people.

The word guaraná comes from the Guaraní word guara-ná, which has its origins in the Sateré-Maué word for the plant, warana, that in Guaraní means "fruit like the eyes of the people" or "eyes of the gods".

Guaraná plays an important role in Tupi and Guarani culture. According to a myth attributed to the Sateré-Maué tribe, guaraná's domestication originated with a deity killing a beloved village child. To console the villagers, a more benevolent god plucked the left eye from the child and planted it in the forest, resulting in the wild variety of guaraná. The god then plucked the right eye from the child and planted it in the village, giving rise to domesticated guarana.

The Guaranis make a herbal tea by shelling, washing and drying the seeds, followed by pounding them into a fine powder. The powder is kneaded into a dough and then shaped into cylinders. This product is known as guaraná bread, which is grated and then immersed into hot water along with sugar.

This plant was introduced to European colonizers and to Europe in the 16th century by Felip Betendorf, Oviedo, Hernández, Cobo and other Spaniard chroniclers. By 1958, guaraná was commercialized.
