Which McDonald's character was designed as the mayor of McDonaldland?

Mayor McCheese was designed as the mayor of McDonaldland.

Mayor McCheese was one of the characters created for McDonald's fictional McDonaldland advertising world. His defining visual feature was a large cheeseburger-shaped head, paired with a formal mayoral outfit. The design turned a familiar menu item into a friendly authority figure for children's advertising.

He appeared alongside Ronald McDonald and other characters, including the Hamburglar, Grimace, and Officer Big Mac. Each character had a distinct role that helped make McDonaldland feel like a complete fictional community rather than a collection of unrelated mascots.

Mayor McCheese is sometimes confused with Officer Big Mac because both represented civic roles in McDonaldland. Their names and jobs were different: Mayor McCheese was the town's mayor, while Officer Big Mac served as its police officer. The character is a branding example of McDonald's turning product imagery into memorable personalities.
