McDonaldland was the fictional advertising town populated by Ronald McDonald and other McDonald's mascots.
The setting gave the company a shared world for television commercials, packaging, restaurant play areas, and promotional products. Characters such as Grimace, the Hamburglar, Mayor McCheese, and Birdie the Early Bird were presented as residents or visitors in this branded universe.
McDonaldland made McDonald's advertising resemble an ongoing children's story rather than a series of unrelated product announcements. Its colorful locations and character designs helped connect menu items with recognizable personalities and visual jokes.
McDonaldland is sometimes used as a general label for the characters, but it specifically names the fictional setting. Ronald McDonald is the central mascot, while McDonaldland is the world in which the character group appears. The campaign's prominence declined as McDonald's advertising strategy changed.
