The Jardin des Plantes de Rouen is a municipal botanical garden located at 7, rue de Trianon, Rouen, Seine-Maritime, Upper Normandy, France. It is open daily without charge.
The garden dates to 1691 when Louis de Carel acquired forest land within which he built a walled garden and pavilion. Scottish banker John Law purchased the garden in 1717, and in 1741, after several other owners, it was opened to the public. In 1806 Sophie Blanchard made a solo balloon ascension from the grounds, in 1811 Napoleon purchased the garden to establish the Sénatorie de la Seine-Inférieure, and in 1817 Élisa Garnerin parachuted from a balloon launched on the site.
