What was McDonald's first chicken product to use the “Mc” prefix in its name?

Chicken McNuggets were McDonald's first chicken product to use the “Mc” prefix in its name.

McDonald's introduced Chicken McNuggets nationally in the United States in 1983. The bite-sized, breaded chicken pieces were shaped for easy serving and marketed as a product with a memorable proprietary name rather than simply as fried chicken.

The product helped expand McDonald's branding beyond hamburgers. Its name combined the chain's “Mc” naming convention with “nuggets,” a familiar food term that made the product easy to recognize.

Chicken McNuggets are often confused with the McChicken sandwich, which is a separate product. The McChicken uses a formed chicken patty in a bun, while McNuggets are small breaded chicken pieces served in portions.
