Chili mac is a dish prepared using chili con carne and macaroni as primary ingredients, which is often topped or intermingled with cheese. Some versions are made using prepared or homemade macaroni and cheese. It is a common dish in the cuisine of the Midwestern United States, and is also popular in other areas of the United States.
Several variations of the dish exist, and prepared canned and boxed versions also exist. It can be a relatively inexpensive dish to prepare, and has been described as a comfort food. Similar dishes include Spaghetti Red, a chili-topped spaghetti popular around Joplin, Missouri, and Cincinnati chili.
