The Hamburglar was the masked thief who first appeared in McDonaldland advertising in 1971.
McDonald’s created the character as part of its fictional McDonaldland universe, a colorful advertising setting populated by food-themed and fantasy characters. In his early appearances, the Hamburglar was portrayed as a small, mischievous figure who tried to steal hamburgers.
The character’s design changed over time. Early versions were more grotesque and spoke in unusual, fragmented language, while later campaigns presented him as a younger, more cartoon-like character wearing a striped outfit and cape.
The Hamburglar is sometimes confused with Captain Crook, who was associated with Filet-O-Fish sandwiches, or with Grimace, who originally had a different advertising role. Their costumes and food associations helped distinguish the McDonaldland cast.
