Which McDonald's mascot was known as the chain's hamburger-headed mayor?

Mayor McCheese was McDonald's mascot known as the hamburger-headed mayor.

The character was one of the most recognizable residents of McDonaldland, the fictional advertising world introduced by McDonald's in 1971. Mayor McCheese wore a suit and ceremonial sash, while his head was designed as a large cheeseburger with facial features.

His title made him a civic leader within the imaginary setting and helped McDonald's give its advertising characters distinct roles. Other McDonaldland figures represented different types of comic or food-related personalities, including the Hamburglar and Officer Big Mac.

Mayor McCheese is sometimes confused with Officer Big Mac because both characters had Big Mac-related designs. The key distinction is that Mayor McCheese had the burger head and mayoral role, while Officer Big Mac was a law-enforcement character with a Big Mac-shaped head.
