Hamburglar was the McDonald's character known for stealing hamburgers in the 1970s.
The Hamburglar appeared in McDonaldland advertising as a small, mischievous figure whose recurring goal was to take McDonald's hamburgers. His striped clothing, cape, and playful behavior made him easy to recognize in television commercials and promotional material.
The character was part of the same broader advertising world as Ronald McDonald, Grimace, and Mayor McCheese. McDonald's later redesigned the Hamburglar with a more modern appearance, but the hamburger-stealing identity remained his defining trait.
He is sometimes confused with Captain Crook, another McDonaldland character. Captain Crook was associated with Filet-O-Fish sandwiches, not hamburgers.
