The Motorcycle Diaries (Spanish: Diarios de motocicleta) is a 2004 biopic about the journey and written memoir of the 23-year-old Ernesto Guevara, who would several years later become internationally known as the iconic Marxist revolutionary Che Guevara. The film recounts the 1952 expedition, initially by motorcycle, across South America by Guevara and his friend Alberto Granado. As the adventure initially centered around youthful hedonism unfolds, Guevara discovers himself transformed by his observations on the life of the impoverished indigenous peasantry.

The screenplay is based primarily on Guevara's travelogue The
