Head cheese (Dutch: hoofdkaas) or brawn is a cold cut terrine or meat jelly that originated in Europe. It is made with flesh from the head of a calf or pig (less commonly a sheep or cow), typically set in aspic, and usually eaten cold, at room temperature, or in a sandwich. Despite its name the dish is not a cheese and contains no dairy products. The parts of the head used vary, and may include the tongue and sometimes the feet and heart but do not commonly include the brain, eyes or ears. Trimmings from more commonly eaten cuts of pork and veal are often used, with gelatin added as a binder.

Variations of head cheese exist throughout Europe and the rest of the world, with differences in construction and ingredients. A version pickled with vinegar is known as souse. Historically, meat jellies were made of the head of an animal, less its organs, which would be simmered to produce a naturally gelatinous stock that would congeal as the dish cooled. Meat jellies made this way were commonly a peasant food and have been made since the Middle Ages. Modern head cheese recipes may require additional gelatin, or more often need to be reduced to set properly.
