Jean-Antoine-Gabriel Davioud (French: [ʒɑ̃ ɑ̃twan ɡabʁijɛl davju]; 30 October 1824 – 6 April 1881) was a French architect. He worked closely with Baron Haussmann on the transformation of Paris under Napoleon III during the Second Empire. Davioud is remembered for his contributions to architecture (e.g. the two theaters on the place du Châtelet and the city hall of the 19th arrondissement), parks (e.g. the Pré Catelan garden and the square des Batignolles) and urban amenities (fountains, pavilions, benches and kiosks). These contributions now form an integral part of the style of Haussmann's Paris.
