McDonald's called its fictional world of characters and locations McDonaldland.
McDonaldland was created as a branded fantasy setting for McDonald's advertising, especially commercials aimed at children. It included recognizable figures, food-themed locations, and a consistent imaginative world connected to the restaurant chain.
The setting helped McDonald's turn individual characters into a broader brand universe. Ronald McDonald was the central figure, while other characters represented different parts of the playful fictional environment.
McDonaldland is often confused with the name of a single character or with the restaurant chain's corporate name. It refers to the entire fictional setting, not to one mascot. Several McDonaldland characters have since disappeared from regular advertising.
