What was the name of McDonald's 1960s mascot whose head was shaped like a hamburger?

Mayor McCheese was McDonald's 1960s mascot whose head was shaped like a hamburger.

The character combined a cheeseburger-like head with a mayoral sash and formal clothing. This visual joke made the character immediately connected to McDonald's food while placing him in the imaginary civic world of McDonaldland.

Mayor McCheese is sometimes mixed up with Officer Big Mac, another food-themed McDonaldland character. Their names and roles were different, although both used menu items as part of their designs.

The character demonstrates how McDonald's branding moved beyond logos and slogans into a complete cast of food-based personalities. These characters gave television commercials a consistent setting and helped the company communicate with children through fantasy and humor.
