Mandu, or mandoo, are dumplings in Korean cuisine. Mandu can be steamed, boiled, pan-fried, or deep-fried. The styles also vary across regions in the Korean Peninsula. Mandu were long part of Korean royal court cuisine, but are now found in supermarkets, restaurants, and snack places such as pojangmacha and bunsikjip throughout South Korea.

Dumpling is a broad class of dishes that consist of pieces of cooked dough, often wrapped around a filling. The dough can be based on bread, wheat or other flours, or potatoes, and it may be filled with meat, fish, tofu, cheese, vegetables, or a combination. Dumplings may be prepared using a variety of cooking methods and are found in many world cuisines.
