Clamart (French pronunciation: [klamaʁ] ⓘ) is a commune in the southwestern suburbs of Paris, France.

Close to Paris and its central marketplace (Les Halles), Clamart's peas were the first of the season.

As de Gaulle's black Citroën DS 19[3] sped through Petit-Clamart it was met by a barrage of submachine-gun fire.

On a former EDF research site, construction on a new urban development (zone d'aménagement concerté or ZAC), overlooking the man-made Panorama Lake (Lac du Panorama) and consisting of new homes, commercial and business space, two schools, and a nursery, began in summer 2018.

The first residents moved in in late 2019, and the schools were two thirds full by 2021 when the second phase of construction was underway.
