Dimocarpus longan, commonly known as the longan (UK: /ˈlɒŋɡən/; US: /ˈlɑːŋɡən/), is a tropical tree that produces edible fruit. It is one of the better-known tropical members of the soapberry family (Sapindaceae), to which the lychee also belongs. It is native to Southern Asia.



The fruit is sweet, juicy and succulent in superior agricultural varieties and, apart from being eaten fresh, is also often used inAsian soups, snacks, desserts, and sweet-and-sour foods, either fresh or dried, sometimes canned with syrup.
