Hôtel Bony, Private mansion in the 9th arrondissement of Paris, France.

Hôtel Bony is a Charles X-style private mansion at 32 rue de Trévise in the 9th arrondissement of Paris, built in 1826 by architect Jules de Joly for contractor René Bony. Its cream-coloured facade has a tall wrought-iron fence with spear-tipped bars between stone pillars, arched ground-floor windows and a door behind the fence, tall rectangular windows with iron balconies above, and smaller windows on the upper level, with oval medallions and carved figures set between them. The entrance courtyard is reached from the end of the alley at 13 rue Bleue, while the garden facade faces 32 rue de Trévise.

Jules-Jean-Baptiste de Joly built the hôtel particulier in 1826 for René Bony, a public works contractor. It was later lived in by Marshal Édouard Mortier, Duke of Trévise, the name borne by the street. The facades, the staircase with First Empire drawings and the large salon were inscribed as monuments historiques in 1927; the building was partly classified on 8 April 1976 and its gate on 15 July 1986.

The building's name comes from René Bony, the public works contractor who commissioned it in 1826. It was later home to Marshal Édouard Mortier, Duke of Trévise, the title recalling the Spanish battle of Trévise that gave the street its name. The staircase decorated with First Empire drawings and the large salon in Revolution style are listed with the facades.

The courtyard entrance is reached from the end of the alley at 13 rue Bleue, while the garden facade is seen from 32 rue de Trévise. The building is occupied by a company and is not open to visitors; the facades, staircase and grand salon are protected as monuments historiques.

Marshal Édouard Mortier, Duke of Trévise, lived in the mansion after its construction; the street name recalls his title. The wrought-iron gate itself was separately inscribed as a monument historique on 15 July 1986, ten years after the building's partial classification of 8 April 1976.
