El Señor Presidente (Mister President) is a 1946 novel written in Spanish by Nobel Prize–winning Guatemalan writer and diplomat Miguel Ángel Asturias (1899–1974). A landmark text in Latin American literature, El Señor Presidente explores the nature of political dictatorship and its effects on society. Asturias makes early use of a literary technique now known as magic realism. One of the most notable works of the dictator novel genre, El Señor Presidente developed from an earlier Asturias short story, written to protest social injustice in the aftermath of a devastating earthquake in the author's home town.

Although El Señor Presidente does not explicitly identify its setting as early twentieth-century Guatemala, the novel's title character was inspired by the 1898–1920 presidency of Manuel Estrada Cabrera. Asturias began writing the novel in the 1920s and finished it in 1933, but the strict censorship policies of Guatemalan dictatorial governments delayed its publication for thirteen years.
