Gabriel García Márquez's One Hundred Years of Solitude was first published in 1967.
The Spanish-language novel, originally titled Cien años de soledad, was published in May 1967 by Editorial Sudamericana in Buenos Aires. It tells the multigenerational story of the Buendía family and the fictional town of Macondo, blending political history, family drama, myth, and supernatural events in a style commonly associated with magical realism.
The book became one of the defining works of twentieth-century Latin American literature. Its international success helped bring the Latin American literary “Boom” to a global audience and established García Márquez as a major modern novelist. He received the Nobel Prize in Literature in 1982.
Readers sometimes select 1970 because that was the year the first English translation, by Gregory Rabassa, appeared. The question asks for the novel's first publication, however, which was the original Spanish edition in 1967. The English edition came later and should not replace the canonical publication year.
