Appearances of Argentine Marxist revolutionary Che Guevara (1928–1967) in popular culture are common throughout the world. Although during his lifetime he was a highly politicized and controversial figure, in death his stylized image has been transformed into a worldwide emblem for an array of causes, representing a complex mesh of sometimes conflicting narratives. Che Guevara's image is viewed as everything from an inspirational icon of revolution, to a retro and vintage logo. Most commonly he is represented by a facial caricature originally by Irish artist Jim Fitzpatrick and based on Alberto Korda's famous 1960 photograph titled Guerrillero Heroico. The evocative simulacra abbreviation of the photographic portrait allowed for easy reproduction and instant recognizability across various uses. For many around the world, Che has become a generic symbol of the underdog, the idealist, the iconoclast, or the martyr. He has become, as author Michael Casey notes in Che's Afterlife: The Legacy of an Image, "the quintessential postmodern icon signifying anything to anyone and everything to everyone."

Ernesto "Che" Guevara was an Argentine Marxist revolutionary, physician, author, guerrilla leader, diplomat, and military theorist. A major figure of the Cuban Revolution, his stylized visage has become a ubiquitous countercultural symbol of rebellion and global insignia in popular culture.
