Which McDonaldland character had a cheeseburger for a head?

The McDonaldland character with a cheeseburger for a head was Mayor McCheese.

Mayor McCheese was one of the recurring characters created for McDonald's fictional advertising world. His defining visual feature was a large cheeseburger-shaped head, paired with formal clothing and mayoral accessories. The design made the character immediately identifiable in television commercials and promotional materials.

He represented the civic side of McDonaldland, serving as its mayor rather than as a villain or mascot for a particular menu item. Other characters had different roles: the Hamburglar tried to steal hamburgers, while Grimace was a large purple companion of Ronald McDonald.

The character illustrates how McDonald's branding in the 1970s used food-shaped designs and exaggerated personalities to make menu items memorable to children. Mayor McCheese is sometimes confused with Officer Big Mac, another food-themed character, but their names and roles were different.
