Edmond Dantès and his aliases
- Edmond Dantès (born 1796): A sailor with good prospects, engaged to Mercédès. After his transformation into the Count of Monte Cristo, he reveals his true name to his enemies as each revenge is completed. During the course of the novel, he falls in love with Haydée.
- The Count of Monte Cristo: The identity Dantès assumes when he emerges from prison and inherits his vast fortune. As a result, the Count of Monte Cristo is usually associated with a coldness and bitterness that comes from an existence based solely on revenge.
- Chief Clerk of the banking firm Thomson & French, an Englishman
- Lord Wilmore: An Englishman, and the persona in which Dantès performs random acts of generosity.
- Sinbad the Sailor: The persona that Dantès assumes when he saves the Morrel family and assumes while mixing with smugglers and brigands.
- Abbé Busoni: The persona of an Italian priest with religious authority.
- Monsieur Zaccone: Dantès, in the guise of the Abbé Busoni, and again as Lord Wilmore, tells an investigator that this is the Count of Monte Cristo's true name.
- Number 34: The name given to him by the new governor of Château d'If. Finding it too tedious to learn Dantès' real name, he was called by the number of his cell.
- The Maltese Sailor: The name he was known by after his rescue by smugglers from the island of Tiboulen.
- Abbé Faria: Italian priest and sage. Imprisoned in the Château d'If. Edmond's dearest friend while in prison.

- Ali: Monte Cristo's mute Nubian slave.
- Baptistin: Monte Cristo's valet-de-chambre.
- Jacopo Manfredi: A poor smuggler who helps Dantès survive after he escapes prison. When Jacopo proves his selfless loyalty, Dantès rewards him with his own ship and crew.
- Haydée (sometimes spelled as Haidee): Monte Cristo's young, beautiful slave. She is the daughter of Ali Tebelen. She is a major part of Dantès' plan to get revenge on Fernand. At the end, she and Monte Cristo become lovers.
- Mercédès Mondego (née Herrera): A Catalan girl, Edmond Dantès' lover and fiancée at the beginning of the story. She later marries Fernand and they have a son named Albert. Despite being in a totally not unhappy marriage with Fernand and being adored and respected by him, and vice-versa, part of her heart can't ignore the past love for Edmond or completely forget him, remaining in love with him. It is due to her love for Edmond that she is able to recognize him when she meets him again, which frightens her. At the end, she returns in Marseilles, living in the house that belonged to father Dantès, given to her by Monte-Cristo himself (to allow the woman a safe and stable place to spend in quietness the rest of her days, with a little financial support: the same francs the young Dantès, before the arrest, used to keep aside in view of their wedding, in a little bag remained hidden in the house’s garden for all the time), praying for Albert, who left France for Africa as a soldier to start a new and more honorable life. Left all alone, she and Edmond talked for the last time: once young and in love, they choose to take different paths, saying farewell to each other. While the Count went away to complete his plan, Mercédès decides to stay in her hometown, with only her memories left of the happiest years, waiting for Albert's return, wishing for Edmond to find peace for his wounded heart and praying on her husband's grave for his soul. She is portrayed as a compassionate, kind and caring woman who prefers to think for her beloved ones than for herself.
- Fernand Mondego: Count de Morcerf (former Catalan fisherman in the Spanish village near Marseilles), Dantès's rival and cousin of Mercédès, for whom he swore undying love and the person he eventually marries. Fernand helped frame Edmond (by sending the accusation letter) in an ultimate desperate attempt to not lose Mercédès forever. He would later achieve the high-rank of general in the French army and become a peer of France in the Chambre des Pairs, keeping secret his betrayal to the Pasha Alì Tebelen, and the selling of both his daughter Haydée and her mother Vasiliki. With the money earned he bought the title of "Count de Morcerf" to bring wealth and a more pleasant life to him and his family. Through the book he shows a deep affection and care for his wife and son. He would meet his tragic end in the last chapters, by committing suicide, in the despair of having lost Mercédès and Albert, disowned by them when they discovered his hidden crimes.
- Albert de Morcerf: Son of Mercédès and Fernand, and the Viscount de Morcerf, fond of Monte Cristo and sees him as a friend. After acknowledging the truth of his father's war crimes and the false accusation towards the sailor Edmond Dantès, he decides to leave his home with Mercédès and start a new life as a soldier under the name of "Herrera" (his mother's maiden name), leaving for Africa in search of fortune and to give new honor upon his family name.
