The Count of Monte Cristo is an adventure novel written by French author Alexandre Dumas completed in 1844. It is one of the author's more popular works, along with The Three Musketeers.

The story takes place in France, Italy, and islands in the Mediterranean during the historical events of 1815–1839: the era of the Bourbon Restoration through the reign of Louis-Philippe of France. It begins on the day that Napoleon left his first island of exile, Elba, beginning the Hundred Days period when Napoleon returned to power. The historical setting is a fundamental element of the book, an adventure story centrally concerned with themes of hope, justice, vengeance, mercy, and forgiveness. It centers on a man who is wrongfully imprisoned, escapes from jail, acquires a fortune, and sets about exacting revenge on those responsible for his imprisonment.

Before he can marry his fiancée Mercédès, Edmond Dantès, a nineteen-year-old Frenchman, and first mate of the Pharaon, is falsely accused of treason, arrested, and imprisoned without trial in the Château d'If, a grim island fortress off Marseille. A fellow prisoner, Abbé Faria, correctly deduces that his jealous rival Fernand Mondego, envious crewmate Danglars, and double-dealing magistrate De Villefort turned him in. Faria inspires his escape and guides him to a fortune in treasure. As the powerful and mysterious Count of Monte Cristo (Italy), Dantès arrives from the Orient to enter the fashionable Parisian world of the 1830s and avenge himself on the men who conspired to destroy him.

The book is considered a literary classic today. According to Lucy Sante, "The Count of Monte Cristo has become a fixture of Western civilization's literature, as inescapable and immediately identifiable as Mickey Mouse, and the story of Little Red Riding Hood
