Mayor McCheese was introduced in 1971 as McDonaldland’s giant-headed, cheeseburger-themed mayor.
McDonaldland was a fictional setting created for McDonald’s advertising, populated by colorful characters linked to menu items and restaurant imagery. Mayor McCheese had a large cheeseburger for a head and wore a formal mayoral outfit, making him one of the campaign’s most distinctive figures.
The character appeared alongside figures such as Ronald McDonald, the Hamburglar, and Grimace. These characters helped McDonald’s build a recognizable children’s advertising world rather than relying only on product shots or slogans.
Mayor McCheese is sometimes confused with Officer Big Mac, another McDonaldland figure whose design also referenced a McDonald’s menu item. Their titles and appearances were different: Mayor McCheese represented the fictional town’s leadership, while Officer Big Mac was its police character.
