Asimina triloba, the American papaw, pawpaw, paw paw, or paw-paw, among many regional names, is a species of small deciduous tree. It has large leaves and produces a large, yellowish-green to brown fruit.

The species is native to eastern North America, in a more temperate range than its tropical relatives. It is a patch-forming (clonal) understory tree of hardwood forests, being found in well-drained, deep, fertile bottomland and also hilly upland habitat.

Although much of the plant contains the neurotoxin annonacin, the ripe fruits are edible. They are sweet, with a custard-like texture and a flavor somewhat similar to banana or pineapple. They are commonly eaten raw, but are also used to make ice cream and baked desserts.
