Which McDonald's character was the mayor of the fictional McDonaldland community?

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

Mayor McCheese had a human body and a large cheeseburger-shaped head. His civic title made him the official leader of McDonaldland, distinguishing him from characters such as Officer Big Mac, who served as a police officer, and the Hamburglar, who was portrayed as a hamburger thief.

The character was part of the McDonaldland campaign introduced in 1971. The fictional community gave McDonald's a way to present menu items as characters and to build recurring stories for television commercials and other promotional material.

Mayor McCheese is sometimes confused with Ronald McDonald because both were central figures in the same advertising universe. Ronald was the principal human-like clown mascot, while Mayor McCheese was specifically the town's elected-style leader and a personification of a cheeseburger.
