The Thiérache (French pronunciation: ​[tjeʁaʃ]) is a region of France and Belgium united by similar geography and architecture, including the presence of hedgerows, grassland, hilly terrain, scattered settlements, and traditionally-built stone or brick houses with stone dividing walls and slate roofs.


Located in the north-east of the Aisne department, it also spills over into parts of the Nord and Ardennes departments and the Walloon provinces of Hainaut and Namur. Its overall location is the western foothills of the Ardennes massif. Historically, its capital was Guise, even though its largest settlement is now Fourmies. It is bisected by the route nationale 2 between Paris and Brussels, whilst another important local route is the route nationale 43 between Cambrai and Charleville-Mézières.
