Officer Big Mac was the McDonaldland character known for guarding McDonald’s hamburgers as a police officer.
He was designed as a law-enforcement figure within the fictional McDonaldland setting, with a head shaped like a Big Mac. His role created a comic contrast with the Hamburglar, whose advertising identity centered on trying to steal hamburgers. The two characters therefore helped McDonald’s turn menu items into a playful story world.
Officer Big Mac is sometimes confused with Mayor McCheese because both represented authority figures. Mayor McCheese was the town’s mayor, while Officer Big Mac was the police character. Their separate jobs were part of the internal structure of McDonaldland advertising.
