The Archdiocese of Rouen (Latin: Archidioecesis Rothomagensis; French: Archidiocèse de Rouen) is a Latin Church archdiocese of the Catholic Church in France.

Normandy was annexed to France in 1204, and Rouen was later occupied by England from 1419 to 1449 during the Hundred Years' War.

In 1562 the city was briefly captured by Huguenots during the French Wars of Religion.

The suffragan dioceses of Rouen in the Middle Ages were Évreux, Avranches, Seès, Bayeux, Lisieux, and Coutances.

[6] The cathedral was heavily damaged, along with other buildings in Rouen, during World War II and later rebuilt.
