The McDonald’s character with a Big Mac-shaped head who served as a police officer in McDonaldland was Officer Big Mac.
Officer Big Mac was designed as a personified version of McDonald’s signature Big Mac sandwich. His police-officer role made him part of the story-like social structure of McDonaldland, where different characters had recognizable jobs and personalities.
He is often confused with Mayor McCheese because both characters had food-shaped heads and official-looking roles. Mayor McCheese had a cheeseburger head and served as mayor, while Officer Big Mac had a Big Mac head and served as a police officer.
The character demonstrates McDonald’s use of menu items as visual branding devices. By turning a named sandwich into a mascot, the company connected product recognition with the larger fictional world used in its advertising.
