Château de Tancarville is an 11th-century castle on a cliff overlooking the Seine in France.

In 1418 at the time of the conquest of Normandy by Henry V of England, the title of Count of Tancarville was given to John Grey, while in the kingdom of France it was used by the House of Harcourt who recovered the castle after the departure of the English.

In 1709, a wing in classical style was added to the medieval parts of the building by the Count of Evreux.

For 29 years, from 1910 to 1939, the castle was rented by Mr. Fernand Prat and his wife born Jehanne Leblanc (sister of Maurice Leblanc) who received many personalities of the arts and letters such as Maurice Maeterlinck and his companion Georgette Leblanc, Colette, Margaret Caroline Anderson, James Joyce, Bertrand de Jouvenel, Pierre Lecomte Nouy and Louis Fabulet.

The castle now belongs to Saqqara, a real estate company in Figeac (Lot), which has been offering luxury apartments since 2001.
