The Musée Cognacq-Jay is a museum located in the Hôtel Donon in the 3rd arrondissement at 8 rue Elzévir, Paris, France. It is open daily except Monday; admission is free. The nearest Metro stations are Saint-Paul and Chemin Vert.
The museum's collection was formed between 1900–1925 by Théodore-Ernest Cognacq and his wife Marie-Louise Jay, founders of La Samaritaine department store. At his death, Cognacq gave the collection to the City of Paris, which in 1929 inaugurated the Musée Cognacq-Jay at 25 boulevard des Capucines, a building especially conceived for it by the Cognacq couple, who wished to display the collection in the intimacy of a seemingly inhabited home, without the conventions of a museum.
