The Three Musketeers is a story by Alexander Dumas, who told the story of the adventures of d'Artagnan and his friends, as they are involved in intrigues involving the weak King Louis XIII of France, his powerful and cunning advisor Cardinal Richelieu, the beautiful Queen Anne of Austria, her English lover, George Villiers, 1st Duke of Buckingham, and the siege of the rebellious Huguenot city of La Rochelle. Adding to the intrigue are the mysterious Milady de Winter, and Richelieu's right-hand man, Comte de Rochefort.

Some elements of another Dumas story: The Man in the Iron Mask are sometimes mixed with the Three Musketeer story. The Three Musketeers is part of a series by Dumas, The D'Artagnan Romances which consist of The Three Musketeers (1844), Twenty Years After (1845), and The Vicomte de Bragelonne (1847). The latter is usually published in English in three parts: The Vicomte de Bragelonne, Louise de la Valliere, and The Man in the Iron Mask.
