Which McDonald's mascot was a burger thief introduced in the early 1970s?

The Hamburglar was the McDonald's mascot portrayed as a burger thief introduced in the early 1970s.

He became one of the best-known residents of McDonaldland. Early versions of the character used an exaggerated black-and-white costume, cape, mask, and speech style. Later redesigns made him look younger and more cartoon-like while keeping the central idea of a character who wanted to steal hamburgers.

The Hamburglar is often confused with Captain Crook, another McDonaldland villain associated with Filet-O-Fish advertising. They represented different product and character concepts. The Hamburglar's name specifically combines “hamburger” with the word “burglar.”

His role shows how McDonald's branding turned menu items into characters and stories. Rather than advertising only the taste or price of a hamburger, the commercials created a playful conflict that children could remember. The character appeared alongside Ronald McDonald, Grimace, and Mayor McCheese before McDonald's later reduced its use of the McDonaldland cast.
