Brisket is a cut of meat from the breast or lower chest of beef or veal. The beef brisket is one of the nine beef primal cuts, though the definition of the cut differs internationally. The brisket muscles include the superficial and deep pectorals. As cattle do not have collar bones, these muscles support about 60% of the body weight of standing or moving cattle. This requires a significant amount of connective tissue, so the resulting meat must be cooked correctly to tenderize it.

Brisket can be cooked many ways, including baking, boiling and roasting. Basting of the meat is often done during the cooking. This normally tough cut of meat, due to the collagen fibers that make up the significant connective tissue in the cut, is tenderised when the collagen gelatinises, resulting in more tender brisket. The fat cap, which is often left attached to the brisket, helps to keep the meat from drying during the prolonged cooking necessary to break down the connective tissue in the meat. Water is necessary for the conversion of collagen to gelatine, which is the hydrolysis product of collagen.

Popular methods in the United States include rubbing with a spice rub or marinating the meat, and then cooking slowly over indirect heat from charcoal or wood. This is a form of smoking the meat. A hardwood, such as oak, pecan, hickory or mesquite is sometimes added, alone or in combination with other hardwoods, to the main heat source. Sometimes, they make up all of the heat source, with chefs often prizing characteristics of certain woods. The smoke from the woods and from burnt dripping juices further enhances the flavor. The finished meat is a variety of barbecue. Smoked brisket done this way is popular in Texas barbecue. Once finished, pieces of brisket can be returned to the smoker to make burnt ends. Burnt ends are most popular in Kansas City-style barbecue, where they are traditionally served open-faced on white bread.
