Officer Big Mac was the police-officer character in McDonald’s early McDonaldland advertising cast.
The character was a personified Big Mac with a police role, extending the restaurant’s menu branding into a fictional world of food-themed mascots. His design connected the character directly to McDonald’s flagship sandwich while giving the McDonaldland stories a recognizable authority figure.
McDonaldland advertising featured several other characters, including Mayor McCheese, Grimace, Captain Crook, and the Hamburglar. Their roles and appearances changed over time, and some were used more heavily in particular periods.
Officer Big Mac is sometimes confused with Mayor McCheese because both characters had civic or official roles. Mayor McCheese was the hamburger-headed mayor, while Officer Big Mac was the character presented as a police officer.
