Breadfruit (Artocarpus altilis) is a species of flowering tree in the mulberry and jackfruit family (Moraceae) believed to have been selectively bred in Polynesia from the breadnut (Artocarpus camansi). Breadfruit was spread into Oceania via the Austronesian expansion and to further tropical areas during the Colonial Era. British and French navigators introduced a few Polynesian seedless varieties to Caribbean islands during the late 18th century. Today it is grown in 90 countries throughout South and Southeast Asia, the Pacific Ocean, the Caribbean, Central America and Africa. Its name is derived from the texture of the moderately ripe fruit when cooked, similar to freshly baked bread and having a potato-like flavor.
The trees have been widely planted in tropical regions, including lowland Central America, northern South America, and the Caribbean. In addition to the fruit serving as a staple food in many cultures, the light, sturdy timber of breadfruit has been used for outriggers, ships, and houses in the tropics.
Breadfruit is very closely related to A. camansi (breadnut or seeded breadfruit) of New Guinea, the Maluku Islands, and the Philippines, A. blancoi (tipolo or antipolo) of the Philippines, and slightly more distantly to A. mariannensis (dugdug) of Micronesia, all of which are sometimes also referred to as "breadfruit". It is also closely related to the jackfruit.
