Guerrilla Warfare () is a book by Marxist revolutionary Che Guevara that was written right after the Cuban Revolution and published in 1961. It soon became the guidebook for thousands of guerrilla fighters in various countries around the world. Guevara dedicated the book to his recently deceased comrade Camilo Cienfuegos, "who should have read and corrected it, but whose fate prevented him from carrying out the task."
