Which McDonald's mascot was introduced in 1961 as the chain's mayor?

Mayor McCheese was the McDonald's mascot introduced in 1961 as the chain's fictional mayor.

The character had a large cheeseburger for a head, a pink suit, a sash, and a top hat. He appeared as the mayor of McDonaldland, the fantasy setting used in McDonald's advertising.

Mayor McCheese was part of a group of food-themed characters created during the company's major expansion of television advertising. His appearances helped turn individual menu items into recognizable personalities for children.

He is sometimes confused with Officer Big Mac, another McDonaldland character whose head was a Big Mac. Mayor McCheese represented the town's civic leader rather than its police officer.
