Alfred Griner Packer, also known as the "Colorado Cannibal", was an American prospector and self-proclaimed wilderness guide who confessed to cannibalism during the winter of 1874. After emerging as the sole survivor of a six-man party who had attempted to travel through the San Juan Mountains of the Colorado Territory, he eventually confessed to having lived off the flesh of his companions, giving more than one version of his account as to the circumstances.

The Legend of Alfred Packer is a 1980 American biographical Western film directed by Jim Roberson from a script by Burton Raffel. It is a biopic of Alferd Packer starring Patrick Dray in the title role. The film features a score by Bolivian composer Jaime Mendoza-Nava, though the main theme is derivative of Mason Williams's "Classical Gas".
