The German occupation of Belgium (, ) of World War I was a military occupation of Belgium by the forces of the German Empire between 1914 and 1918. Beginning in August 1914 with the invasion of neutral Belgium, the country was almost completely overrun by German troops before the winter of the same year as the Allied forces withdrew westwards.

Low-level expressions of dissent were common but frequently repressed. From August 1918, the Allies advanced into occupied Belgium during the Hundred Days Offensive, liberating some areas. For most of the country, however, the occupation was only brought to an end in the aftermath of the armistice of November 1918 as the Belgian Army advanced into the country to replace evacuating German troops in maintaining law and order. Background Following its independence in 1830, Belgium had been obliged to remain neutral in perpetuity by an 1839 treaty as part of a guarantee for its independence. Before the war, Belgium was a constitutional monarchy and was noted for being one of the most industrialised countries in the world.
