Which McDonaldland character was portrayed as a cheeseburger-headed mayor?

Mayor McCheese was McDonaldland’s cheeseburger-headed mayor.

The character appeared in McDonald’s advertising beginning in the early 1970s, when the company developed McDonaldland as a fictional setting for its restaurant characters. Mayor McCheese wore a mayoral sash and had a large cheeseburger for a head, making his design immediately recognizable to children.

Mayor McCheese is sometimes confused with Officer Big Mac, whose head was shaped like a Big Mac, or with the Hamburglar, whose role centered on stealing hamburgers. McDonaldland also included characters such as Grimace, Captain Crook, and Birdie the Early Bird. The campaign helped turn McDonald’s characters into a larger branded world rather than presenting Ronald McDonald alone.
