Weil am Rhein is a German town and commune. It is on the east bank of the River Rhine, and extends to the tripoint of Switzerland, France, and Germany. It is the most southwesterly town in Germany and a suburb in the Trinational Eurodistrict of Basel. The town has around 30,000 inhabitants, and the Eurodistrict metropolitan area has about 830,000.

The Battle of Friedlingen took place on 14 October 1702, during the War of the Spanish Succession. Most of the fighting centred around Friedlingen, now a suburb of Weil am Rhein, on the border between the German state of Baden-Württemberg and Switzerland. A French force under Villars defeated an Imperial army commanded by Louis William, Margrave of Baden-Baden.
