What was the name of McDonald's cheeseburger-headed McDonaldland mayor?

Mayor McCheese was McDonald's cheeseburger-headed mayor in the McDonaldland advertising world.

The character appeared in McDonald's commercials and promotional material as a civic leader whose head resembled a cheeseburger. He wore formal mayoral clothing and was one of several fantasy figures created to give the brand a recognizable fictional setting for family advertising.

Mayor McCheese belonged to the same broad McDonaldland cast as Ronald McDonald, Grimace, the Hamburglar, and other characters. His name combined a political title with a direct reference to McDonald's hamburger menu, making the character's role immediately understandable to viewers.

He is sometimes confused with Officer Big Mac, another McDonaldland character whose name referenced a McDonald's sandwich. The two characters had different identities and occupations. Mayor McCheese was particularly prominent in older television advertising and later became associated with the nostalgic visual history of McDonald's branding.
