Xiaolongbao refers to a type of small Chinese steamed bun (baozi) traditionally prepared in a xiaolong, a small bamboo steaming basket. Xiaolongbao are often referred to as a kind of "dumpling", but are distinct from Chinese jiaozi or wonton.

Baozi, or simply bao, is a type of yeast-leavened filled bun in various Chinese cuisines. There are many variations in fillings and preparations, though the buns are most often steamed. They are a variation of mantou from Northern China.
