Which McDonald's mascot appeared in advertising as the Mayor of McDonaldland?

Mayor McCheese was the McDonald's mascot portrayed as the mayor of McDonaldland.

The character had a human-like body and a large cheeseburger for a head, combining a civic title with one of McDonald's signature foods. Mayor McCheese appeared in advertisements alongside Ronald McDonald and other residents of the McDonaldland universe.

His design made the branding concept especially literal: the character's identity, title, and appearance all pointed to the restaurant's menu. This kind of visual wordplay helped young viewers distinguish the many characters in McDonald's advertising.

Mayor McCheese is often confused with Officer Big Mac because both characters used food-based names and appeared in the same fictional world. They were separate characters with different roles. McDonaldland campaigns were especially prominent during the 1970s and 1980s, although many of the original characters later disappeared from mainstream advertising.
