Weiswampach (Luxembourgish: Wäiswampech [væːɪsˈvɑmpəɕ] ⓘ or locally Wäiswampich) is a commune and small town in northern Luxembourg, in the canton of Clervaux.

The French Revolution marked a turning point for Weiswampach, when it became a municipality governed by a mayor.

The improvement of road infrastructure and the creation of subdivisions, among other things, has since caused an increase in population to 1399 people in 2011.

The main road through Weiswampach, with its connections to Belgium, the Netherlands and North-West of Germany, as well as the favorable geographical location, has caused intense transit, which in turn has resulted in the construction of gas stations, hotels and restaurants.

There is also a recreation and holiday center containing 65 hectares, with two artificial lakes and 276 campsites in a natural setting, which has greatly contributed to tourism.
