Mayor McCheese first appeared in 1971 as the mayor of McDonaldland.
McDonaldland was a fantasy setting created for McDonald’s advertising, populated by characters based on menu items and restaurant themes. Mayor McCheese was depicted with a giant cheeseburger for a head and served as the setting’s civic leader.
The character belonged to a larger group that included Ronald McDonald, the Hamburglar, Grimace, Birdie the Early Bird, and others. These figures helped McDonald’s build a continuing fictional world for television commercials, restaurant displays, and merchandise.
Mayor McCheese is sometimes confused with Officer Big Mac, another McDonaldland character whose head was also based on a menu item. The mayor’s defining role was political leadership, while Officer Big Mac was associated with law enforcement.
