McDonaldland was the name of McDonald’s fictional advertising world for its mascots.
The setting was introduced in the early 1970s as a colorful fantasy environment populated by characters such as Ronald McDonald, the Hamburglar, Grimace, Mayor McCheese, and Captain Crook. Television commercials used the setting to create recurring stories around McDonald’s food and restaurants.
McDonaldland gave the company a shared narrative structure rather than treating each mascot as an unrelated figure. Its bright landscapes, food-shaped locations, and recurring cast made the advertising especially recognizable to children.
The name is sometimes confused with the characters’ individual names or with the term McDonald’s Playland, which referred to restaurant playgrounds. McDonaldland was an advertising universe; it was not the name of a physical restaurant chain or a standard menu item.
