Offal /ˈɒfəl/, also called, especially in the United States, variety meats or organ meats, refers to the internal organs and entrails of a butchered animal. The word does not refer to a particular list of edible organs, which varies by culture and region, but includes most internal organs other than muscle and bone. As an English mass noun, the term "offal" has no plural form. Some cultures shy away from offal as food, while others use it as everyday food, or in delicacies.

Some offal dishes are considered gourmet food in international cuisine. This includes foie gras, pâté and sweetbreads. Other offal dishes remain part of traditional regional cuisine and may be consumed especially in connection with holidays. This includes Scottish haggis, Jewish chopped liver, Southern U.S. and African-American chitterlings, as well as many other dishes. Intestines are used as casing for sausages, although cheaper types may use artificial casing.

Depending on the context, offal may refer to those parts of an animal carcass discarded after butchering or skinning; it may also refer to the by-products of milled grains, such as corn or wheat. Offal not used directly for human or animal food is often processed in a rendering plant, producing material that is used for fertilizer or fuel; or in some cases, it may be added to commercially produced pet food.

Chris Cosentino is an American chef noted for his specialty, offal dishes, now considered haute cuisine by many, and his eco-consciousness. He is chef-partner at Incanto in San Francisco. He was a competitor on The Next Iron Chef and has appeared on Iron Chef America. As of September 2009, he is writing a book on offal cookery, and he maintains an offal-themed website, Offal Good. Forbes Traveler calls Incanto "perhaps America’s most adventurous nose-to-tail restaurant … On offer are lamb’s necks, pig trotters and a five-course nose-to-tail tasting menu perhaps including venison kidneys and chocolate-blood panna cotta."

Chris was raised in Rhode Island and is a 1994 graduate of Johnson & Wales University. Raised in an Italian American community, he has stated that he hated offal as a child, especially the tripe his Italian grandmother prepared. Since becoming a chef himself, however, he has embraced a "whole-animal" ethic. He explains, "What I try to do is make people understand a whole-animal ethic. When people realize that this is a whole animal, that there is more than just the skeletal meats, sometimes that makes people step back, and they might not order any meat. They might have a vegetable entrée. Putting a face on what you’re eating sometimes opens your eyes a lot."
