Notre-Dame-de-Gravenchon is a former commune in the Seine-Maritime department in the Normandy region in northern France. On 1 January 2016, it was merged into the new commune of Port-Jérôme-sur-Seine.
A small town with a huge industrial area (Port-Jérome) to the southwest with farming and woodland to the north and east, in the Pays de Caux, situated by the banks of the river Seine, some 20 miles (32 km) east of Le Havre, at the junction of the D81, D373 and D110 roads.
- The parishes of Saint-Georges-de-Gravenchon and Notre Dame were part of the royal domain of Lillebonne. The Counts of Évreux built the medieval castle of Fontaine-Saint-Denis. The two parishes were joined as one commune in 1823 under the name of Notre-Dame-de-Gravenchon.
- Napoleon III opened the new industrial area of Port-Jérôme. A commemorative stone recalls his visit on May 28, 1861. Until then, the commune was an agricultural town.
- In 1930, two oil refineries with two separate housing districts were established. "Standard" (for Esso employees) and "Vacuum" (for Mobil Oil's workers).
- During World War II, the refineries were partly destroyed (1940) but rebuilt after 1945. Notre Dame de Gravenchon has been occupied by the Germans as from 12 June 1940 and liberated on 31 August 1944 jointly by the British and Belgian armies (Brigade Piron).
