Teak is indigenous to India, Burma, Thailand, Indochina and Java, but it has been extensively planted for timber or as an ornamental within its natural range and throughout the tropical regions of the world, including East and West Africa, the West Indies, from Cuba and Jamaica to Trinidad, and from Panama to Brazil. It is also grown in southern Florida. The species has also been cultivated experimentally or at low elevations in Puerto Rico.
