Who was the mayor of McDonaldland in McDonald's advertising?

Mayor McCheese was the mayor of McDonaldland in McDonald's advertising.

The character had a human-like body and an oversized cheeseburger for a head. His design turned a recognizable McDonald's food item into a civic mascot, reinforcing the connection between the fictional world and the restaurant's menu.

Mayor McCheese appeared alongside characters such as Ronald McDonald, the Hamburglar, Grimace, and Officer Big Mac. These figures helped McDonald's present its advertising as a continuing fantasy world rather than a series of unrelated product commercials.

Mayor McCheese is sometimes confused with Officer Big Mac because both represented authority figures. Their roles were different: Mayor McCheese was the elected civic leader, while Officer Big Mac was the police character.
