Which fictional town served as the setting for McDonald's character advertising?

McDonaldland was the fictional town used as the setting for McDonald's character advertising.

The setting was introduced in the early 1970s as a colorful world populated by characters connected to McDonald's food and restaurant imagery. Ronald McDonald served as its best-known resident, while the cast also included the Hamburglar, Grimace, Mayor McCheese, Officer Big Mac, and Captain Crook.

McDonaldland gave McDonald's a consistent narrative framework for television commercials, playground designs, packaging, and promotional materials. Instead of presenting each mascot in isolation, the company could place them in a recognizable branded environment with recurring locations and relationships.

The name is sometimes confused with the restaurant chain itself or with later children-focused promotional programs. McDonaldland specifically refers to the fictional setting and its associated characters. Its importance in branding history comes from turning fast-food advertising into an interconnected fantasy world, especially for children during the 1970s and 1980s.
