Nabisco (/nəˈbɪskoʊ/; originally known as the National Biscuit Company) is an American brand of cookies and snacks. Headquartered in East Hanover, New Jersey, the company is a subsidiary of Illinois-based Kraft Foods. Nabisco's plant in Chicago, a 1,800,000-square-foot (170,000 m²) production facility at 7300 S. Kedzie Avenue, is the largest bakery in the world, employing more than 1,500 workers and turning out some 320 million pounds of snack foods annually.

Its products include Chips Ahoy!, Fig Newtons, Mallomars, Oreos, Ritz Crackers, Teddy Grahams, Triscuit, Wheat Thins, Social Tea, Nutter Butter, Peek Freans, Chicken in a Biskit, used for the United States, United Kingdom, Mexico and Venezuela as well as other parts of South America.

Nabisco products are branded as Kraft in some other countries. All Nabisco cookie or cracker products are branded Christie in Canada; however, prior to the Post Cereals merger, the cereal division kept the Nabisco name in Canada. The proof of purchase on their products is marketed as a "brand seal". The Nabisco name became redundant in Canada after Kraft took over.
