Mayor McCheese was the McDonaldland character depicted with a cheeseburger for a head and presented as the town's mayor.
McDonaldland was a fictional advertising setting created by McDonald's for campaigns aimed especially at children. Its characters turned menu items and restaurant imagery into recognizable personalities, helping the company build a distinctive brand world beyond the restaurant sign and product packaging.
Mayor McCheese appeared as a large, formal-looking character with a cheeseburger head, a mayoral sash, and other civic-leader details. He was one of several McDonaldland figures associated with Ronald McDonald. He is sometimes confused with Officer Big Mac, whose design was based on a Big Mac and whose role was connected with law enforcement rather than town government. McDonald's later reduced its use of many McDonaldland characters, but Mayor McCheese remains one of the brand's best-known historical advertising figures.
