Which 1970s McDonald's mascot had a cheeseburger for a head?

Mayor McCheese was the McDonald's mascot whose head was shaped like a cheeseburger.

Mayor McCheese appeared as the mayor of McDonaldland, the fictional advertising setting used by McDonald's during the 1970s and later. His design combined a formal mayoral outfit with an exaggerated cheeseburger head, making the character directly recognizable as a McDonald's creation.

The character was part of a larger group that included Ronald McDonald, the Hamburglar, Grimace, and Birdie the Early Bird. Each figure had a different role, allowing advertisements to present McDonald's products through stories and playful character interactions.

Mayor McCheese is sometimes confused with the Hamburglar because both were prominent McDonaldland figures. Their designs and roles were different: Mayor McCheese represented civic authority in the fantasy setting, while the Hamburglar was defined by his attempts to steal hamburgers.
