Soumagne (French pronunciation: [sumaɲ], Walloon: Soûmagne) is a municipality of Wallonia located in the province of Liège, Belgium.

The municipality consists of the following districts: Ayeneux, Cerexhe-Heuseux, Évegnée-Tignée, Mélen, Micheroux, and Soumagne.

From the end of the 19th century until the 1960s, Soumagne was a flourishing municipality with numerous coal mines and a large Cooperative factory.

During the German invasion of Belgium at the beginning of World War I, the Imperial German Army killed 118 civilians and burned 100 houses in the village as collective punishment for the Belgian Army’s resistance of the invasion from the nearby Fort de Fléron.

[3] Since 1980, the higher number of people leaving big cities (Liège and Verviers) for more rural municipalities, with the E40 motorway passing on its territory, Soumagne recovered from the loss of coal mining and the end of the Cooperative.
