The Battle of Elsenborn Ridge refers to the northernmost German attacks during the Battle of the Bulge. The area from Elsenborn Ridge itself to Monschau was the only sector of the American front line attacked during the Battle of the Bulge in which the Germans failed to advance. The battle centred on the boomerang-shaped Elsenborn Ridge east of Elsenborn, Belgium. In this region, Elsenborn Ridge marks the westernmost ridge of the Ardennes, rising more than 2,000 feet (600 m) above sea level; unlike the uplands further north, east and south, it has been extensively logged. West of Elsenborn Ridge, where the land descends in gentle hills to the cities of Liège and Spa, was a network of Allied supply bases and a well-developed road network. The Germans planned on using two key routes through the area to seize Antwerp and force a separate peace with the United States and Britain. Capturing Monschau, the nearby village of Höfen, and the twin villages of Rocherath-Krinkelt just east of Elsenborn Ridge, were key to the success of the German plans, and Hitler committed his best armored units to the area.

The Battle of the Bulge, also known as the Ardennes Offensive, was the last major German offensive campaign on the Western Front during World War II which took place from 16 December 1944 to 25 January 1945. It was launched through the densely forested Ardennes region between Belgium and Luxembourg. The offensive was intended to stop Allied use of the Belgian port of Antwerp and to split the Allied lines, allowing the Germans to encircle and destroy each of the four Allied armies and force the western Allies to negotiate a peace treaty in the Axis powers' favor.
