The Parc de Saint-Cloud (pronounced [paʁk də sɛ̃ klu]; Park of Saint-Cloud), officially the Domaine national de Saint-Cloud (pronounced [dɔmɛn nɑsjɔnal də sɛ̃ klu]; National Estate of Saint-Cloud), is a domaine national (national estate) located mostly within the Saint-Cloud commune, in the Hauts-de-Seine department, southwest of Paris, France.
The park, which covers 460 hectares (1,100 acres), was a nature reserve on the left bank of the Seine until 1923. It was centred around the former Château de Saint-Cloud, home of Philippe I, Duke of Orléans (1640–1701), which was destroyed by French bombing in 1870 during the Franco-Prussian War after the Prussians had made a base of it. The château was the meeting place of the Council of Five Hundred and Council of Ancients on 10 November 1799, the day following Napoleon's Coup of 18 Brumaire.
On 9 November 1994 the Parc de Saint-Cloud was classified a historical monument. In 2005 it was awarded the Notable Garden status. The park is operated as a domaine national under the Ministry of Culture's Centre des monuments nationaux (CMN).
