The Warche is a river in eastern Belgium (province of Liège).
From its source at Losheimergraben on the Belgian-German border, it flows roughly west about 50 kilometres (31 mi), across the south of the Hautes Fagnes region.
It passes through the town of Malmedy, and the artificial lakes of Robertville and of Bütgenbach are formed by dams on the Warche. It is a right tributary of the river Amblève, which it joins east of Stavelot.
