The Old Gringo (Spanish: Gringo Viejo) is a novel by Carlos Fuentes, written from 1964 to 1984 and first published in 1985. Inspired by the historical disappearance of American writer Ambrose Bierce amidst the chaos of the Mexican Revolution, the novel addresses themes of death, cultural exchange, and Mexican identity, among others. Its English-language translation became the first novel by a Mexican author to become a U.S. bestseller.
