What was the name of McDonald's hamburger mascot introduced in 1971?

The Hamburglar was the McDonald's hamburger mascot introduced in 1971.

The character appeared as part of McDonaldland, a fantasy world created for McDonald's advertising. In his earliest form, the Hamburglar was a small, mischievous figure who tried to steal hamburgers, making him a comic foil for the brand's more friendly characters. His striped clothing, cape, and oversized hat made him visually easy for children to recognize.

The Hamburglar was not the same character as Grimace, Mayor McCheese, or Ronald McDonald. Those figures had different roles within the advertising universe: Grimace was associated with shakes, Mayor McCheese represented McDonaldland, and Ronald served as the central mascot.

McDonald's later redesigned the Hamburglar in a more modern, taller form during the 1980s. The character remains one of the best-known examples of fast-food branding built around a recurring fictional cast.
