Bamboos are found as natural flora in many parts of the world, from sea level to the snowy mountains, in tropical, subtropical, and mild temperate climates, with 1678 species classified into 123 genera. They are found in abundance in Asia's southern and south-eastern borders, from India to China and Japan to Korea. Bamboos are found in Africa, Australia, and Madagascar, among other places. In the Western hemisphere, bamboos extend from the eastern United States to Chile and Argentina. South America is also rich in bamboo.

Three major bamboo-growing geographical regions are recognized in the world:

  1. Asia-Pacific (42°S-51°N): This includes major bamboo-growing countries like China, India, Myanmar, Thailand, Cambodia, Japan, etc.
  2. American (47°S-40°N): The American bamboo growing region extends across the south and north Americas, Mexico, Guatemala, Honduras, Columbia, Venezuela, and the Amazon valley in Brazil. These are the main centres of bamboo distribution in this region. Brazil has the greatest diversity of bamboos followed by countries like Colombia, Venezuela, Ecuador, Costa Rica, Mexico, and Peru.
  3. African (22° S-16° N): Southern Mozambique and eastern Sudan from south to north. The main places are Senegal, Guinea, Liberia, Ivory Coast, Nigeria, Congo, Zaire and, Madagascar Island. The tropical clumping bamboos species like Cathariostachys, Cephalostachyum, Oxytenanthera and Schizostachyum; and a handful of temperate bamboos, belonging to Bergbambos, Oldeania, Thamnocalamus and Yushania are found in this region.
