Ouvrage Latiremont is a gros ouvrage of the Maginot Line, located in the Fortified Sector of the Crusnes, sub-sector of Arrancy. It lies between the gros ouvrage Fermont and the petit ouvrage Mauvais Bois, facing Belgium. The village of Doncourt-Cités is nearby. Latiremont was active in 1939-1940, coming under direct attack in late June 1940. It surrendered to German forces on 27 June. After renovations during the Cold War, it was abandoned.

The Fortified Sector of the Crusnes was the French military organization that in 1940 controlled the section of the Maginot Line extending eastwards approximately 28 kilometres (17 mi) from Longuyon. The sector roughly follows the valley of the Crusnes river. Crucially, the trace of the Maginot Line in the Crusnes sector is about 7 kilometres (4.3 mi) behind the industrial city of Longwy which sits directly against the French borders with Belgium and Luxembourg. The Crusnes sector was one of the strongest Maginot Line sectors. It was attacked in 1940 by German forces in the Battle of France. Despite the withdrawal of the mobile forces that supported the fixed fortifications, the sector successfully fended off German assaults before the Second Armistice at Compiègne. The positions and their garrisons finally surrendered on 27 June 1940. Following the war many positions were reactivated for use during the Cold War. Three locations are now preserved and open to the public, with a fourth position under restoration.
