Kola nut (Cola) is a genus of about 125 species of trees native to the tropical rainforests of Africa, classified in the family Malvaceae, subfamily Sterculioideae (or treated in the separate family Sterculiaceae). It is related to the South American genus Theobroma (Cacao). They are evergreen trees, growing to 20 m tall, with glossy ovoid leaves up to 30 cm long.

It is often used ceremoniously, presented to tribal chiefs or presented to guests. Chewing kola nut can ease hunger pangs. Frequent chewing of the kola nut can also lead to stained teeth. Among the urban youth of West Africa, kola nut is becoming less popular.
Kola was originally used to make cola soft drinks, though today most of these mass-produced beverages use artificial flavourings. Some exceptions are Barr's Red Kola, Harboe Original Taste Cola, Blue Sky Organic Cola, and Cricket Cola, the latter being made from kola nuts and green tea.
Outside of Africa, some species are cultivated for their nuts in Indonesia, Brazil, Jamaica and elsewhere in the humid tropics.
