A patty or burger is a flattened, usually round, serving of ground meat or legumes, grains, vegetables, or meat alternatives. Patties are found in multiple cuisines throughout the world.

Ground meat, called mince or minced meat outside North America, is meat finely chopped by a meat grinder or a chopping knife. A common type of ground meat is ground beef, but many other types of meats are prepared in a similar fashion, including pork, veal, lamb, goat meat, and poultry.
