Chicken McNuggets became a major McDonald’s brand extension when they launched nationally in 1983.
McDonald’s introduced the bite-sized, breaded chicken pieces as a product that could fit the chain’s standardized fast-food system. Their uniform shape, portioning, and dipping-sauce format made them easy to recognize and simple to market to families.
The product’s name followed McDonald’s established naming style, using “Mc” to connect a new menu item to the broader corporate brand. Chicken McNuggets then became one of the company’s best-known products and a recurring focus of packaging, promotions, and licensed advertising.
The item is sometimes confused with the McChicken, which is a separate chicken sandwich. Chicken McNuggets are pieces rather than a sandwich, and their national U.S. launch date is 1983.
