Breadfruit (Artocarpus altilis) is a species of flowering tree in the mulberry family, Moraceae, growing throughout Southeast Asia and most Pacific Ocean islands. Its name is derived from the texture of the cooked fruit, which has a potato-like flavor, similar to fresh-baked bread.

Ancestors of the Polynesians found the trees growing in the northwest New Guinea area around 3500 years ago. They gave up the rice cultivation they had brought with them from ancient Taiwan, and raised breadfruit wherever they went in the Pacific (except Easter Island and New Zealand, which were too cold). Their ancient eastern Indonesian cousins spread the plant west and north through insular and coastal Southeast Asia. It has, in historical times, also been widely planted in tropical regions elsewhere.
