The Hamburglar is McDonald's black-and-white striped thief who steals hamburgers.
The character became part of McDonaldland, McDonald's fictional advertising setting populated by mascots and food-themed figures. His defining visual traits included striped clothing, a small thief-like costume, and a strong obsession with hamburgers.
The Hamburglar was introduced in the early 1970s and later redesigned into a younger, more stylized character. The redesign made him look less threatening and more like a mischievous cartoon companion for children's advertising.
He is often confused with Captain Crook, another McDonaldland character. Captain Crook was associated with Filet-O-Fish sandwiches, whereas the Hamburglar's recurring target was the hamburger. Mayor McCheese, by contrast, was a separate character with a cheeseburger head and a civic role in the fictional setting.
