What was the name of McDonald’s hamburger mascot with a cheeseburger-shaped head?

Mayor McCheese was McDonald’s hamburger mascot with a cheeseburger-shaped head.

The character appeared in McDonaldland advertising, the fantasy world McDonald’s developed for television commercials and promotions. Mayor McCheese wore a mayoral sash and formal clothing, combining civic imagery with the chain’s cheeseburger theme.

The character is sometimes confused with Officer Big Mac, whose head was shaped like a Big Mac, or with the Hamburglar, whose design centered on stealing hamburgers. Mayor McCheese’s defining visual feature was the cheeseburger head.

McDonaldland characters became prominent in McDonald’s marketing during the 1970s. Their designs gave children a cast of recurring figures connected with menu items and restaurant visits.
