Itterswiller (French pronunciation: [itəʁsvilɛʁ]; German: Ittersweiler) is a commune in the Bas-Rhin department in Alsace in north-eastern France.

The village is located on the eastern beginnings of the Vosges Mountains, between Molsheim to the north and Sélestat top the south. It is a few kilometres to the west of the Autoroute A35, the principal north-south highway in Alsace.

Tourism is important to the local economy which is positioned on the Elsässer Weinstraße. The village also takes a pride in its vineyards.

The village is on the course of a Roman road: it is therefore believed that the area must have been settled during the Roman empire period. The name is thought to come from the Latin "Itineris villa" which indicates a hostelry for travellers.

In terms of surviving written records, a so-called Letter of Indulgence to Itterswiller dates from 1330.

An annual church festival takes place at the end of September or start of October.
