Which McDonald’s character was the chief of the McDonaldland world?

Mayor McCheese was the chief of the McDonaldland world in McDonald’s character branding.

Mayor McCheese was introduced in 1971 as a large hamburger-headed character wearing a mayoral sash and formal clothing. He appeared in commercials alongside other McDonaldland characters, including Ronald McDonald, the Hamburglar, Grimace, and Captain Crook.

The character helped McDonald’s build a shared fictional setting rather than advertising each product separately. McDonaldland connected restaurant visits with imaginative stories, playground-like locations, and branded characters aimed primarily at children.

Mayor McCheese is sometimes confused with Ronald McDonald, who was the central human-like mascot and host of the setting. Mayor McCheese’s defining role was civic leadership within McDonaldland, not ownership of the restaurant chain.
