Alexandre Dumas Museum, History museum in Villers-Cotterêts, France.

The Alexandre Dumas Museum is housed in a 19th-century mansion that served as General Maunoury's headquarters during the First World War. Its three rooms are each devoted to one member of the family: General Thomas-Alexandre Dumas, the novelist Alexandre Dumas, and the playwright Alexandre Dumas fils. The collections bring together portraits, personal objects and manuscripts, including travel accounts, drafts of novels, children's stories and memoirs.

The museum tells the story of General Thomas-Alexandre Dumas, his son Alexandre Dumas père, and the younger Alexandre Dumas fils, whose combined careers shaped French literature across a century. The collection spans from the general's work in the 1700s through the younger writer's works in the 1800s.

The museum's three rooms are each devoted to one member of the family: General Thomas-Alexandre Dumas, born in the Antilles and a slave, his son Alexandre Dumas père, author of The Count of Monte Cristo, and Alexandre Dumas fils, the academician. The town also keeps the family link alive through the royal château François 1er, the Saint-Nicolas church, the town hall, the Hôtel de l'Épée and the Abbé-Grégoire college.

The museum occupies a 19th-century mansion at 13 rue Demoustier, spread over three rooms, one for each member of the Dumas family. Guided tours for groups can be booked in advance, and the building is accessible to visitors with reduced mobility. Opening hours change with the season, so check the museum's official website before setting out.

The museum opened in 1905 at 13 rue Demoustier, after the Regional Historical Society of Villers-Cotterêts was asked in 1902, the centenary of Alexandre Dumas's birth, to gather and display Dumas family memorabilia. During the First World War the collections were moved to Dijon to protect them, and in 1952 the museum settled in a 19th-century mansion that had served as General Maunoury's headquarters.
