The Strike of the 100,000 () was an 8-day strike in Belgium which took place from 10–18 May 1941 during the German occupation. It was led by Julien Lahaut, head of the Belgian Communist Party. The object of the strike was to demand a wage increase though it was also an act of passive resistance to the German occupation. In the aftermath of the strike and the repression of Communists following the invasion of Russia, Julian Lahaut was deported to a concentration camp in Germany. Many other strikers were also incarcerated in the fortress of Huy.
