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

Mayor McCheese was the McDonaldland character presented as McDonaldland's mayor.

The character appeared in McDonald's advertising during the early 1970s, when the company developed a large fictional world around Ronald McDonald. Mayor McCheese had a giant cheeseburger for a head and was dressed in formal mayoral clothing, including a sash.

McDonaldland gave McDonald's a way to connect menu items and restaurant visits with recurring characters. The campaign included figures such as the Hamburglar, Grimace, and Officer Big Mac. These characters appeared in television commercials, packaging, playgrounds, and other promotional material.

Mayor McCheese is sometimes confused with Officer Big Mac because both characters were based on menu items. Their roles were different: Mayor McCheese was the civic leader, while Officer Big Mac was associated with law enforcement. McDonaldland later became less prominent as McDonald's advertising moved toward other campaigns.
