Jajangmyeon (Korean: 자장면) or jjajangmyeon (짜장면) is a Korean Chinese noodle dish topped with a thick sauce made of chunjang, diced pork, and vegetables. It originated in Incheon, Korea where Chinese migrant workers brought over zhajiangmian from Shandong in the late 19th century. Modifications in Korea such as a darker and sweeter sauce differentiate the Korean version from the Chinese dish. Variants of the dish use seafood, or other meats.

Korean Chinese cuisine, also known as Sino–Korean cuisine, is a hybrid cuisine developed by the ethnic Chinese in Korea.
