Which McDonald's character was a hamburger-headed mayor in the 1970s?

Mayor McCheese was the McDonald's character portrayed as a hamburger-headed mayor in the 1970s.

He appeared in McDonaldland advertising alongside characters such as Ronald McDonald, Grimace, the Hamburglar, and Birdie. Mayor McCheese wore a formal mayoral outfit, while his oversized hamburger head made the character immediately identifiable as part of the McDonald's food-themed fantasy world.

The character helped turn McDonald's advertising into a recurring fictional setting rather than a series of unrelated commercials. His role was civic and comedic, contrasting with the Hamburglar's mischievous behavior.

Mayor McCheese is sometimes confused with Officer Big Mac, another McDonaldland character. The key distinction is that Mayor McCheese was the hamburger-headed mayor, while Officer Big Mac was associated with law enforcement.
