Which McDonaldland character served as the setting's police officer?

Officer Big Mac was the police officer character in McDonaldland. Introduced during the expansion of McDonald's character advertising in the early 1970s, he was designed with a head modeled on the Big Mac hamburger and wore a police uniform.

Officer Big Mac helped give McDonaldland a recognizable social structure. Mayor McCheese represented the town's leadership, while Officer Big Mac provided its law-enforcement role. Other characters, including the Hamburglar and Captain Crook, were often used in comic storylines involving stolen hamburgers or other playful mischief.

The character connected the company's menu branding to its fictional world. The name “Big Mac” made the link to McDonald's signature sandwich explicit, while the uniform quickly communicated his job to viewers who might not know the character's name.

Officer Big Mac is easy to confuse with Mayor McCheese because both characters had food-based heads and appeared in the same campaign. The distinction is straightforward: Mayor McCheese was the mayor, whereas Officer Big Mac was McDonaldland's police officer.
