Hôtel de Chenizot, Private mansion in Île Saint-Louis, Paris, France.

Hôtel de Chenizot is a private residence on Rue Saint-Louis-en-l'Île on Île Saint-Louis in Paris with an ornate facade and decorative balcony. The building was designed by architect Pierre Vigné de Vigny and displays detailed architectural elements from the period of its renovation.

Jean-François Guyot de Chenizot bought the house in 1719 and had architect Pierre Vigné de Vigny add a balcony and decorate the facades. In 1840 the state leased it for nine years at 12,000 francs a year from Émilie Lafond to house Archbishop Denys Affre. After Affre was fatally wounded at a barricade in June 1848, Parisians filed past his body here before the funeral at Notre-Dame. The state leased it again in 1850 for the 1st Gendarmerie Legion's staff, which stayed until 1862.

The name comes from Jean-François Guyot de Chenizot, who bought the house in 1719 and had architect Pierre Vigné de Vigny add a balcony and decorate the facades. The second courtyard, farthest from Rue Saint-Louis-en-l'Île, keeps buildings from late 19th-century light industry, such as lampshade frames, and a sundial like the one at the Hôtel de Lauzun.

The building is now divided into private apartments and is not open to the public, but visitors can observe its architectural details from the street. The best view is from Rue Saint-Louis-en-l'Île, where you can take in the facade and balcony without obstruction.

French metaphysician and writer René Guénon lived in an apartment here from 1904 to 1930. These were formative years when he developed some of his most influential ideas.
