Which McDonald's character was a police officer and friend of Ronald McDonald?

Officer Big Mac was the McDonaldland character portrayed as a police officer and friend of Ronald McDonald.

McDonaldland was a fictional world created for McDonald’s advertising, especially during the 1970s. Its characters turned menu items and restaurant ideas into a colorful cast aimed primarily at children. Officer Big Mac was designed as a law-enforcement-themed character, with the appearance of a Big Mac incorporated into his identity. He appeared alongside Ronald McDonald and other residents in commercials and promotional materials.

The character is easy to confuse with Mayor McCheese, another anthropomorphic food character who held a civic role in McDonaldland. Their titles and visual designs were different: Officer Big Mac was the police character, while Mayor McCheese was the town’s mayor.

McDonaldland character branding eventually became less central to McDonald’s mainstream advertising. Ronald McDonald remained the best-known figure, while several supporting characters appeared less often or disappeared from newer campaigns. The characters nevertheless remain an important part of the chain’s branding history.
