Jorge Mario Pedro Vargas Llosa, 1st Marquess of Vargas Llosa, more commonly known as Mario Vargas Llosa, is a Peruvian novelist, journalist, essayist and former politician. Vargas Llosa is one of Latin America's most significant novelists and essayists and one of the leading writers of his generation. Some critics consider him to have had a larger international impact and worldwide audience than any other writer of the Latin American Boom. In 2010, he won the Nobel Prize in Literature, "for his cartography of structures of power and his trenchant images of the individual's resistance, revolt, and defeat." He also won the 1967 Rómulo Gallegos Prize, the 1986 Prince of Asturias Award, the 1994 Miguel de Cervantes Prize, the 1995 Jerusalem Prize, the 2012 Carlos Fuentes International Prize, and the 2018 Pablo Neruda Order of Artistic and Cultural Merit. In 2021, he was elected to the Académie française.

The Latin American Boom was a literary movement of the 1960s and 1970s when the work of a group of relatively young Latin American novelists became widely circulated in Europe and throughout the world. The Boom is most closely associated with Julio Cortázar of Argentina, Carlos Fuentes of Mexico, Mario Vargas Llosa of Peru, and Gabriel García Márquez of Colombia. Influenced by European and North American Modernism, but also by the Latin American Vanguardia movement, these writers challenged the established conventions of Latin American literature. Their work is experimental and, owing to the political climate of the Latin America of the 1960s, also very political. "It is no exaggeration", critic Gerald Martin writes, "to state that if the Southern continent was known for two things above all others in the 1960s, these were, first and foremost, the Cuban Revolution and its impact both on Latin America and the Third World generally, and secondly, the Boom in Latin American fiction, whose rise and fall coincided with the rise and fall of liberal perceptions of Cuba between 1959 and 1971."
