What was the name of McDonald's character with a cheeseburger for a head?

Mayor McCheese was the McDonald's character with a cheeseburger for a head. He appeared as the mayor of McDonaldland, the fictional setting used in the company's family advertising.

The character wore formal mayoral clothing and was designed around an oversized cheeseburger head. This visual joke made him immediately recognizable to children and connected the fantasy world directly to McDonald's food branding.

Mayor McCheese appeared with other McDonaldland figures, including Ronald McDonald, the Hamburglar, and Grimace. The characters gave McDonald's commercials a continuing cast rather than presenting each advertisement as an unrelated product message.

He is sometimes confused with Officer Big Mac, another McDonaldland figure associated with a hamburger-themed design. Mayor McCheese's defining role, however, was political: he was presented as the fictional world's mayor.
