Ficus elastica, the rubber fig, rubber bush, rubber tree, rubber plant, or Indian rubber bush, Indian rubber tree, is a species of plant in the fig genus, native to eastern parts of South Asia and southeast Asia. It is a large tree in the banyan group of figs, growing to 30–40 metres (98–131 ft) (rarely up to 60 metres or 200 feet) tall, with a stout trunk up to 2 metres (6.6 ft) in diameter. The trunk develops aerial and buttressing roots to anchor it in the soil and help support heavy branches. In parts of India, people guide the roots of the tree over chasms to eventually form living bridges. This was the case in the one I saw in Mawlynnong, Meghalaya. "Deep in the dense tropical forest of Meghalaya, and shrouded in cloud and rain for much of the year, are some astonishing man-made natural wonders. Known as living root bridges, inventive members of the Khasi tribe have trained them to grow from the roots of ancient rubber trees, native to the northeast region. The root bridges provide a stable alternative to wooden bridges, which decay and get destroyed during the lengthy monsoon seasons. It takes around 15 years for a new root bridge to become strong enough to bear the weight of people crossing it. However, it will continue to grow and strengthen even more over time. Some of the bridges are believed to be hundreds of years old, although no one knows their exact age."

Ficus elastica yields a milky white latex, a chemical compound separate from its sap and carried and stored in different cells. This latex was formerly used to make rubber, but it should not be confused with the Pará rubber tree, the main commercial source of latex for rubber making.
