The McChicken is a chicken sandwich sold by the international fast food restaurant chain McDonald's. The sandwich consists of a toasted wheat bun, a breaded chicken patty, shredded lettuce, and mayonnaise.

The sandwich, originally introduced in 1980, proved to be a sales disappointment and was later replaced with the highly successful Chicken McNuggets. But following the success of McNuggets, the McChicken was reintroduced in 1988. But again, McDonald's removed the McChicken from its menus in the United States on September 26, 1996,[3] and it was replaced with the Crispy Chicken Deluxe, which was part of McDonald's ill-fated Deluxe line of sandwiches. But once again, the McChicken was brought back gradually towards the later months of 1997, due to overwhelming letters and petitions. Additionally, in the United States, the sandwich is somewhat smaller than it was previously, as it is now on the Dollar Menu & More (previously just the Dollar Menu), which offers various food products starting at US$1.00.

The meat of the McChicken sandwich used to be 50% white meat and 50% dark meat. Viewed in April 2015, McDonald's website states that the McChicken contains a blend of dark and white meat chicken.
