What name did McDonald's use for its fictional mayor character in McDonaldland?

McDonald's named its fictional McDonaldland mayor Mayor McCheese.

Mayor McCheese was a humanlike character with a large cheeseburger for a head. He appeared as the official mayor of McDonaldland, turning the restaurant's menu imagery into a recognizable civic-style character. His design fit the broader strategy of giving products and restaurant ideas personalities that children could remember.

The character was part of the same advertising world as Ronald McDonald, Grimace, and the Hamburglar. McDonaldland gave McDonald's a consistent setting for television commercials, promotional material, and character-based storytelling. Mayor McCheese added an authority figure to that world, although the campaigns generally treated him as a comic and friendly personality rather than a serious political character.

Mayor McCheese is sometimes confused with the restaurant's mascots that had simpler product-based names. The exact name matters: “Mayor McCheese” combines the civic title with the Mc-prefixed naming style used across McDonaldland. The character later became less prominent as McDonald's advertising changed.
