The Hamburglar was the McDonald's character known for stealing hamburgers in the original McDonaldland advertising cast.
The character appeared as a small, mischievous figure whose central joke was his desire to take hamburgers. His name combined “hamburger” with the word “burglar,” making the role immediately understandable to audiences, especially children.
The Hamburglar was part of the broader McDonaldland promotional world that included Ronald McDonald, Grimace, Mayor McCheese, and other branded figures. Like the other characters, he helped McDonald's turn menu items and restaurant visits into a recurring fictional setting.
The Hamburglar's appearance changed over time. Early versions looked older and more villainous, while later redesigns presented him as a smaller, more childlike character. This evolution is why photographs and advertisements from different decades can look quite different while depicting the same mascot.
