Sartrouville (French: [saʁtʁuvil] ⓘ) is a commune in the Yvelines department, Île-de-France, north central France.

In the Middle Ages the name Sartrouville was recorded in Medieval Latin as Sartoris Villa.

Others believe that the word sartoris comes from the Medieval Latin past participle exsartum ("cleared for cultivation"), from Latin sartum ("hoed"), and means "estate of the land-clearers", probably in reference to the deforestation that took place around Sartrouville in Antiquity or in the Early Middle Ages to enable the cultivation of the land.
