Migas (Spanish pronunciation: [ˈmiɣas], Portuguese pronunciation: [ˈmiɣɐʃ]) ("crumbs" in English) is a dish traditionally made from stale bread and other ingredients in Spanish and Portuguese cuisines. Originally introduced by shepherds, migas are very popular across the Iberian Peninsula, and are the typical breakfast of hunters at monterías in some regions of Spain.

The same name is used for a different dish made from maize or flour tortillas in Mexican and Tex-Mex cuisines.

Migas is a traditional dish in Spanish cuisine. It was originally a breakfast dish among shepherds that made use of leftover bread or tortas. It gained greater uptake as shepherds, cooking on small braziers while moving their sheep along transhumance routes, spread the dish to rural laborers. It regained popularity during the early 20th century, and as of 2011 was sold by restaurants across Spain, and in supermarkets, vacuum-sealed and ready to be heated. The most suitable Spanish bread for making migas is called "candeal", due to its dense and spongy crumb. Migas is usually served as a first course for lunch or dinner in restaurants in Spain.

The ingredients of migas vary across the provinces of Spain. In Extremadura, this dish includes day-old bread soaked in water, garlic, paprika, and olive oil. In Teruel, Aragon, migas includes chorizo and bacon, and is often served with grapes. In La Mancha, migas manchegas is a more elaborate preparation using basically the same ingredients as Aragonese migas. In Granada, Almería and Murcia, in southeastern Spain, migas is similar to North African couscous, using flour and water, but no bread. Preparations commonly feature a variety of ingredients, including fish. Andalusian migas is often eaten with sardines as a tapa, in the form of fried breadcrumbs. In some places the dish is eaten on the morning of the matanza (butchery) and is served with a stew including curdled blood, liver, kidneys, and other offal, traditionally eaten right after butchering a pig, a sheep or a goat. Migas is often cooked over an open stove or coals. In Almería, migas is a staple dish when it rains, yet the reason is still subject to much discussion.

Migas is also a traditional dish in Portuguese cuisine. It is usually made with leftover bread, either pao Alentejano, a wheat bread traditionally associated with the Alentejo region in Southern Portugal, or corn bread as used in Beira. In Alentejo, migas can also be made with potatoes (migas de batata) instead of bread.

Garlic and olive oil are always an ingredient. Other ingredients such as pork meat drippings, wild asparagus, tomato, and seasonings such as red pepper paste and fresh coriander are usually included in Alentejo, while in Beira, the other ingredients typically include cooked kale cut in caldo verde style, cooked beans (pinto, black-eyed peas or kidney beans), and sometimes cooked rice.

Migas usually accompanies meats or other main dishes.

In different areas of Mexico, migas is a traditional breakfast dish consisting of crispy crumbled corn tortilla chips, to which scrambled eggs are mixed in. This preparation makes use of hardened corn tortillas left over from previous meals. Chilaquiles is a similar meal with whole fried tortilla chips and salsa, where eggs or chicken are added during the cooking process. Both are hearty, inexpensive working-class breakfast meals.
