The Maltese Falcon is a 1930 detective novel by American writer Dashiell Hammett, originally serialized in the magazine Black Mask beginning with the September 1929 issue.

The main character, Sam Spade (who also appeared later in some lesser-known short stories), was a departure from Hammett's nameless detective, The Continental Op. Spade combined several features of previous detectives, notably his cold detachment, keen eye for detail, unflinching, sometimes ruthless, determination to achieve his own form of justice, and a complete lack of sentimentality. In 1990 the novel ranked 10th in "Top 100 Crime Novels of All Time" list by the Crime Writer's Association. Five years later in a similar list by Mystery Writers of America the novel was third.
