The Count of Monte Cristo (French: Le Comte de Monte-Cristo) is an adventure novel by French author Alexandre Dumas (père). Complete in 1844, it is one of the author's most popular works, along with The Three Musketeers. Like many of his novels, it is expanded from plot outlines suggested by his collaborating ghostwriter Auguste Maquet.

The story takes place in France, Italy, islands in the Mediterranean, and in the Levant during the historical events of 1815–1838. It begins from just before the Hundred Days period (when Napoleon returned to power after his exile) and spans through to the reign of Louis-Philippe of France. The historical setting is a fundamental element of the book. An adventure story primarily concerned with themes of hope, justice, vengeance, mercy and forgiveness, it focuses on a man who is wrongfully imprisoned, escapes from jail, acquires a fortune and sets about getting revenge on those responsible for his imprisonment. However, his plans have devastating consequences for the innocent as well as the guilty.
