The McDonaldland character with a hamburger-shaped head who served as mayor was Mayor McCheese.
Mayor McCheese was one of the most distinctive figures in McDonald’s fictional advertising world. His oversized cheeseburger head, formal mayoral clothing, and civic role turned a menu item into a character that could appear in recurring stories and commercials.
The character belonged to the McDonaldland ensemble, which helped McDonald’s create a playful setting around its restaurants and products. Other characters had different designs and roles, including Officer Big Mac and Ronald McDonald.
Mayor McCheese is sometimes mistaken for the earlier Speedee mascot because both are connected with McDonald’s branding history. They are separate characters from different phases: Speedee represented service speed, while Mayor McCheese belonged to the later fantasy advertising world.
