Nostromo: A Tale of the Seaboard is a 1904 novel by Joseph Conrad, set in the mining town of Sulaco, an imaginary port in the western region of the imaginary country of Costaguana.
The book has more fully developed characters than any other of his novels, but two characters dominate the narrative: Señor Gould and the eponymous anti-hero, the "incorruptible" Nostromo.
