What 1960s McDonald's character was based on the restaurant chain's Big Mac sandwich?

Officer Big Mac was the 1960s McDonald's character based on the Big Mac sandwich.

Officer Big Mac belonged to the McDonaldland cast, a group of fictional figures used to make McDonald's advertising more imaginative and appealing to children. The character was designed as a police officer and had a head resembling a Big Mac, linking the role and appearance directly to one of the chain's signature products.

The Big Mac itself was introduced in 1967 by Jim Delligatti, a McDonald's franchisee. The character emerged during the broader period when McDonald's was building a colorful advertising world around its menu and restaurant experience.

Officer Big Mac is often mixed up with Mayor McCheese because both characters had burger-shaped heads. Their names identify different burger references and different roles: Officer Big Mac was a law-enforcement character, while Mayor McCheese held the mayoral title.
