Tancarville (French pronunciation: [tɑ̃kaʁvil]) is a commune in the Seine-Maritime department in the Normandy region of northern France.

Tancarville is a farming village surrounded by woodland, by the banks of the river Seine in the Pays de Caux, some 14 miles (23 km) east of Le Havre and near the junction of the D39, D982 and D910 roads at the eastern end of the A131 autoroute.

Germanic male given name Tankrad > Tancred, common in the duchy of Normandy.

The first lords of Tancarville were the chamberlains of the Norman dukes, and then of the King of England too.

The title Earl of Tankerville was created in the Peerage of England for John Grey by King Henry V, during the Hundred Years' War and still exists, albeit in a later creation.
