Officer Big Mac was the police-officer character in McDonald's original McDonaldland character group.
The character appeared in the fantasy setting used for McDonald's advertising from the early 1970s. Officer Big Mac was designed as a walking version of the Big Mac, connecting the restaurant's signature sandwich with the wider cast of branded characters.
McDonaldland advertising used exaggerated visual identities to make menu items and restaurant experiences memorable to children. Officer Big Mac's uniform and law-enforcement role gave the character a clear place in the fictional community, while his hamburger-shaped head linked him directly to McDonald's products.
He is sometimes confused with Captain Crook, another McDonaldland character. Captain Crook was a pirate associated with Filet-O-Fish, whereas Officer Big Mac represented the Big Mac and served as McDonaldland's police officer.
