The Petit Luxembourg ("Little Luxembourg") is a French hôtel particulier, currently the residence of the president of the French Senate. It is located at 17–17 bis, rue de Vaugirard, just west of the Senate's main building, the Palais du Luxembourg, in the 6th arrondissement of Paris. Originally built around 1550 to the designs of an unknown architect, it is especially noted for the surviving Rococo interiors designed in 1710–1713 by the French architect Germain Boffrand. Further west, at 19 rue de Vaugirard, is the Musée du Luxembourg.
