A meatball is ground or minced meat rolled into a small ball, sometimes along with other ingredients, such as bread crumbs, minced onion, eggs, butter and seasoning.

Meatballs are cooked by frying, baking, steaming, or braising in sauce.

There are many types of meatballs using different types of meats and spices. The term is sometimes extended to meatless versions based on vegetables or fish.
