Which McDonald's character served as McDonaldland's police officer?

Officer Big Mac served as McDonaldland’s police officer.

Officer Big Mac was a McDonald’s advertising character with a large Big Mac-shaped head. His title and costume presented him as the law-enforcement figure in McDonaldland, the fictional setting used in the company’s 1970s and later promotions.

He belonged to the same ensemble as Mayor McCheese, Captain Crook, the Professor, Grimace, and the Hamburglar. Giving each character a distinct job helped McDonald’s commercials create recurring stories rather than isolated product announcements. Officer Big Mac’s role also connected the fantasy world to familiar civic institutions such as policing and local government.

The character is often confused with Mayor McCheese because both had food-based heads and appeared in the same advertisements. The identifying distinction is their office: Mayor McCheese was the town’s mayor, while Officer Big Mac was its police officer. The character later disappeared from most mainstream McDonald’s advertising as the company simplified its brand presentation.
