'''Cergy''' ({{IPA|fr|sɛʁʒi|-|Fr-Paris--Cergy.ogg}}) is a [[Communes of France|commune]] in the French [[Departments of France|department]] of [[Val-d'Oise]], to the northwest of Paris. It is located {{convert|27.8|km|mi|abbr=on}} from the [[Kilometre zero#France|centre of Paris]], in the "[[new town#France|new town]]" of [[Cergy-Pontoise]], created in the 1960s, of which it is the central and most populated commune.

Although neighbouring [[Pontoise]] is the official ''[[préfecture]]'' (capital) of the [[Val-d'Oise]] ''[[département in France|département]]'', the ''préfecture'' building and administration, as well as the department council (''conseil général''), are located inside the commune of Cergy. The ''[[Subprefectures in France|sous-préfecture]]'' building and administration, on the other hand, are located inside the commune of Pontoise.

==Name==
The name Cergy comes from [[Medieval Latin]] ''Sergiacum'', meaning "estate of Sergius", a [[Gallo-Roman]] landowner.

==Administration==

The new [[Hôtel de Ville, Cergy|Hôtel de Ville]] (town hall) was completed in 1990.<ref>{{cite web|url= https://locations.filmfrance.net/location/city-cergy-les-gemeaux-building-city-hall-global-information   |title= Ville de Cergy – Immeuble les Gémeaux|publisher=Film France| access-date=12 March 2025}}</ref>

==Demographics==
When Cergy was selected to become the center of a "[[new town#France|new town]]", it was only a village. The commune had only 2,895 inhabitants in 1968. It then started to develop very quickly, exceeding 10,000 inhabitants in the mid-1970s and then 20,000 in the early-1980s. It is in this decade that its growth was most spectacular, since the city exceeded 48,000 inhabitants in 1990. The increase continued since, but at a notably slower pace, to reach 54,500 at 2004 estimates. However, in December 2001, the commune lost a portion of its territory (net {{convert|0.03|km2|sqmi|abbr=on}} with a 1999 population of 62 persons) to the adjacent commune of [[Courdimanche]].<ref>{{cite web|url=https://www.legifrance.gouv.fr/jorf/id/JORFTEXT000000771032|title=Décret du 4 décembre 2001 portant modification des limites territoriales de communes et de cantons du département du Val-d'Oise|website=[[Légifrance]]|language=fr}}</ref> The official census figures have thus been revised downward from the 1999 official 54,781 to 54,719, and the land area from {{convert|11.68|km2|sqmi|abbr=on}} to 11.65&nbsp;km<sup>2</sup>.

[[File:Tour EDF Cergy-Pontoise (France).jpg|thumb|[[EDF-GDF tower]], Cergy-Pontoise (France)]]
The town was used as a filming location for [[Henri Verneuil]]'s film [[I... comme Icare]] released in 1979, starring [[Yves Montand]]. The [[EDF-GDF tower]] designed by architect [[Renzo Moro]] is the building from which the shots were fired to assassinate president Marc Jarry.
The country that the movie depicts is not named, although the United States is perhaps suggested.
The filmmakers chose the modern and innovative architecture of the new city to avoid depicting any particular country.<ref>{{cite web
