Which McDonald's character is a thief who wears black-and-white striped clothing?

The Hamburglar is the McDonald's character portrayed as a thief in black-and-white striped clothing.

He was one of the central figures in McDonaldland advertising and was depicted trying to steal hamburgers. The character's striped outfit, cape, and exaggerated speech made him visually distinct from Ronald McDonald and the other mascots.

The Hamburglar's appearance changed over the decades. Early versions looked older and more mischievous, while later redesigns presented him as a smaller, younger character. These changes reflected broader shifts in children's advertising and the visual style of McDonald's campaigns.

The name is a wordplay combining “hamburger” with “burglar.” Although the character was fictional, the joke was immediately understandable across McDonald's advertising. He became one of the brand's most recognizable supporting mascots alongside Grimace and Mayor McCheese.
