Gertwiller (German: Gertweiler) is a commune in the Bas-Rhin department in Alsace in north-eastern France.

[3] Positioned in the heart of the Alsace wine growing region, Gertwiller specialises in the manufacture of pain d'épices, a traditional sweet spicey confection not dissimilar from ginger bread.

Pain d'épice from Gertwiller became famous through the nineteenth and twentieth centuries and can be found at almost every village market or fête in the region.

In its time Gertwiller has received the title of French capital of pain d'épice, in succession to more substantial settlements such as Rheims and Dijon.

Gertwiller is traversed by the little River Kirkneck which joins the Andlau near to Valff.
