Mayor McCheese was voiced by actor and comedian Howard Morris in early McDonald's commercials.
Mayor McCheese was one of the most distinctive McDonaldland characters because his head was shaped like a cheeseburger. He was presented as the mayor of the fictional McDonaldland setting and appeared in advertisements alongside Ronald McDonald and other characters.
Howard Morris was a major television performer and voice actor whose work included comedy, animation, and live-action programs. His involvement gave the character a recognizable comic delivery that helped distinguish the mayor from the rest of the advertising cast.
Mayor McCheese is sometimes confused with Officer Big Mac, another McDonaldland figure whose name also used a McDonald's menu item. The character's burger-shaped head and mayoral role are the clearest identifiers. McDonaldland characters were primarily promotional creations, not characters from a standalone film or television series.
