羊不食（学名：Solanum lasiocarpum），又名毛茄，为茄科茄属下的一个种。

Solanum lasiocarpum, otherwise known as Indian nightshade, is a plant that produces edible fruit. Its flowers are white and its fruits are pale yellow. S. lasiocarpum is native to temperate Asia, tropical Asia and the pacific.

S. lasiocarpum is found wild in parts of South Asia, but in a handful of countries it is primarily known as a domesticated plant. Domesticated plants bear larger fruits and lack the prickly skin that is found in the wild plants. The color found in the center of fruit is light green, like that of Solanum quitoense. It's cultivated in tropical Asia, used in food additives for flavoring, and given to the sick as a folk medicine. In India, the locals use the fruit as a sour-relish in curries. In Thailand, a special kind of sauce called nam prek is made with the fruit.
