The Maison de Balzac is a writer's house museum in the former residence of French novelist Honoré de Balzac (1799–1850). It is located in the 16th arrondissement at 47, rue Raynouard, Paris, France, and open daily except Mondays and holidays; admission to the house is free, but a fee is charged for its temporary exhibitions. The nearest métro and RER stations are Passy and Avenue du Président Kennedy.

The modest house, with its courtyard and garden, is located within the residential district of Passy near the Bois de Boulogne. Having fled his creditors, Balzac rented its top floor from 1840 to 1847 under his housekeeper's name (Mr. de Breugnol). It was acquired by the city of Paris in 1949, and is now one of the city's three literary museums, along with the Maison de Victor Hugo and the Musée de la Vie Romantique (George Sand). It is the only one of Balzac's many residences still in existence.
