Carmen Sandiego is the main antagonist of a series of geography games released in the 1980s and 1990s. In games such as "Where in the World is Carmen Sandiego?" and "Where in the USA is Carmen Sandiego?" the player would have to follow Carmen and her cronies as they attempted to steal historical relics such as the Declaration of Independence, the crown jewel of England, or the Golden Gate Bridge.
There was also a TV show in the 1990's based on the games.
