Which McDonald's mascot was a cheeseburger-shaped mayor of McDonaldland?

Mayor McCheese was the cheeseburger-shaped mayor of McDonaldland.

McDonald's introduced Mayor McCheese as part of the fictional McDonaldland setting used in advertising and promotions. The character had a large cheeseburger head, a mayoral sash, and other civic-style details. He appeared alongside Ronald McDonald and characters such as Grimace, the Hamburglar, and Captain Crook.

Mayor McCheese is sometimes confused with Officer Big Mac because both were food-themed authority figures in the same advertising world. Officer Big Mac had a Big Mac head, while Mayor McCheese had a cheeseburger head and served as the mayor. That distinction makes the character's name the precise answer.

McDonaldland gave McDonald's a recurring narrative environment rather than isolated product commercials. Although the characters became less prominent in later marketing, they remain an important part of the company's late-twentieth-century branding history and helped make menu items recognizable through visual personalities.
