The Liège Medal (, ) was an unofficial World War I campaign medal issued by the Belgian city of Liège to its 1914 defenders against the German invaders. It was first issued in April 1920 during a large ceremony presided by the Duke of Brabant (the future King Leopold III) and Lieutenant General the Count Gérard-Mathieu Leman, military commander of the defence of Liège during the battle which raged from the 5th to the 16th of August 1914. The stubborn defence of the city forced the Germans to bring in specialised extra heavy artillery to take on the city fortifications.
