Which McDonald's advertising character was known for stealing hamburgers?

The Hamburglar was the McDonald's advertising character known for stealing hamburgers.

He was one of the principal figures in McDonaldland, the fictional setting created for McDonald's advertising. The character's defining behavior was trying to take hamburgers, usually while wearing a black-and-white striped outfit and a cape.

The Hamburglar's design changed over time. Early versions were portrayed as a small, somewhat sinister-looking figure, while later advertising presented him as a younger and more playful character. Despite the changes, hamburger theft remained the central joke attached to his identity.

The Hamburglar is distinct from Grimace, who was generally portrayed as a friendly companion, and from Officer Big Mac, whose role was connected with law enforcement in McDonaldland. These characters helped McDonald's create a recognizable branded world for children.
