Dak-galbi (Korean: 닭갈비; pronounced [tak̚.k͈al.bi]), or spicy stir-fried chicken, is a popular South Korean dish made by stir-frying marinated diced chicken in a gochujang-based sauce with sweet potatoes, cabbage, perilla leaves, scallions, tteok (rice cake), and other ingredients. In Korean, galbi means rib, and usually refers to braised or grilled short ribs. Dak-galbi is not made with chicken ribs, however, and the dish gained this nickname during the post-War era when chicken was used as a substitute for pork ribs. Many dak-galbi restaurants have round hot plates that are built into the tables. Lettuce and perilla leaves are served as ssam (wrap) vegetables.

This dish was developed in the 1960s as grilled chicken-pieces, an inexpensive anju accompaniment to alcoholic drinks in small taverns on the outskirts of Chuncheon. It replaced the comparatively expensive gui dishes which were grilled over charcoal. Dak-galbi spread to Chuncheon's main districts, where the livestock industry was thriving and offered fresh ingredients with no need for refrigeration. As a relatively cheap dish served in large portions, it gained popularity with soldiers and students on a budget and earned the nickname "commoners' galbi" or "university student's galbi" in the 1970s.

The dish is a local specialty of Chuncheon and is often referred to as Chuncheon-dak-galbi. An annual festival dedicated to dak-galbi is held in Chuncheon, where there is also a dak-galbi alley with a large number of dak-galbi restaurants.

There is a dak-galbi street (닭갈비 거리) in Myeong-dong, Seoul, and there are dozens of restaurants there.
