The McDonaldland character portrayed as a police officer alongside Mayor McCheese was Officer Big Mac.
Officer Big Mac was one of the characters created for McDonald’s McDonaldland advertising. His design turned the Big Mac hamburger into a character, using the sandwich’s name as part of the character’s identity. He was depicted as a police officer within the fictional McDonaldland community.
McDonaldland launched in the early 1970s as a shared advertising world populated by anthropomorphic food items and fantasy figures. Mayor McCheese served as its mayor, while characters such as the Hamburglar and Grimace gave the campaigns recurring personalities and storylines.
Officer Big Mac is less familiar to many modern audiences because McDonald’s later reduced its use of the larger McDonaldland cast. The character should not be confused with the Hamburglar, whose defining role was attempting to steal hamburgers, or with Mayor McCheese, who was identified by his mayoral office rather than a police role.
