The Hamburglar was McDonald's striped-shirt, hamburger-stealing trickster character.
He was part of the group of fictional characters McDonald's developed for family advertising during the 1970s. The character's basic story was simple: he wanted to steal hamburgers, especially McDonald's signature Big Mac, while the other characters tried to stop or outsmart him.
The Hamburglar's costume changed over the years. Earlier versions had a more exaggerated appearance, while later redesigns gave him a younger, more modern look. His recurring role made him easy for children to recognize and helped turn McDonald's advertising into a shared fictional setting.
The character is sometimes mixed up with Mayor McCheese or Captain Crook, who were also members of the McDonaldland cast. The defining Hamburglar trait is his obsession with taking hamburgers, expressed through his name, striped clothing, and playful schemes.
