Gaume

thumb|The countryside near Torgny (village)|Torgny Gaume () is a region in the extreme southeast of Belgium. At a lower altitude than the Ardennes, it borders the French region of Lorraine to the south (although some consider the bordering parts of Lorraine to be Gaume française), the Land of Arlon (Luxembourgish: Arelerland) to the east, and the Belgian part of the Ardennes to the north.

In cultural terms, Gaume is the Romance-speaking part of what is now called Belgian Lorraine, Arelerland being its Luxembourgish-speaking part.
