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

Mayor McCheese was portrayed as the mayor of McDonaldland.

The character was a human-like figure with a large cheeseburger for a head, complete with a sesame-seed bun, cheese, and burger filling. He appeared in McDonald's advertising alongside characters such as Ronald McDonald, Grimace, the Hamburglar, and Birdie the Early Bird.

Mayor McCheese is easy to confuse with Officer Big Mac because both characters used hamburger imagery. Their roles were different: Mayor McCheese was the civic leader of McDonaldland, while Officer Big Mac was a law-enforcement character. McDonaldland's cast helped McDonald's create a recognizable shared advertising setting for children during the 1970s and later decades.
