José Donoso Yáñez (October 5, 1924 – December 7, 1996) was a Chilean writer.
He lived most of his life in Chile, although he spent many years in self-imposed exile in Mexico, the United States (Iowa) and mainly Spain.
Although he had left his country in the sixties for personal reasons, after 1973 he said his exile was also a form of protest against the dictatorship of Augusto Pinochet.
He returned to Chile in 1981 and lived there until his death.
Donoso is the author of a number of noted stories and novels, which contributed greatly to the Latin American literary boom.
The term 'Boom' was coined in his 1972 essay Historia personal del "boom". His best known works include the novels Coronación, El lugar sin límites (The Place Without Limits) and El obsceno pájaro de la noche (The Obscene Bird of Night).
His works deal with a number of themes, including sexuality, the duplicity of identity, psychology, and a sense of dark humor.
