Thérouanne (Dutch: Terwaan; French Flemish Terenburg) is a commune in the Pas-de-Calais department in the Hauts-de-France region of France. It is located 10 km (6.2 mi) west of Aire-sur-la-Lys and 13 km (8.1 mi) south of Saint-Omer, on the D 157 and D 341 road junction. Located on the river Leie (French: Lys).

At the time of the Gauls, Tarwanna or Tervanna was the capital of the Belgian tribe of the Morini. After the Romans conquered Gaul, they too made the city the capital of the Civitas Morinorum district.

In the 7th century, probably around 639, Saint Audomar (Saint Omer) established the bishopric of Terwaan or Terenburg, the diocese of Thérouanne, which during the Middle Ages controlled a large part of the left bank of the river Scheldt. Territorially it was part of the county of Artois which belonged to the county of Flanders.

Thanks to that ecclesiastical control of some of the most prosperous cities north of the Alps, like Arras and Ypres, the bishopric was able to build a cathedral which was at the time the largest in France.
