The scuttling of the French fleet at Toulon was orchestrated by Vichy France on 27 November 1942 to prevent Nazi German forces from seizing it. After the Allied invasion of North Africa, the Germans invaded the territory administered by Vichy under the Armistice of 1940. The Vichy Secretary of the Navy, Admiral François Darlan, defected to the Allies, who were gaining increasing support from servicemen and civilians. His replacement, Admiral Gabriel Auphan, guessed correctly that the Germans intended to seize the large fleet at Toulon, and ordered it scuttled.

Vichy France, officially the French State, was the French rump state headed by Marshal Philippe Pétain during World War II. It was named after its seat of government, the city of Vichy. Officially independent, but with half of its territory occupied under the harsh terms of the 1940 armistice with Nazi Germany, it adopted a policy of collaboration. Though Paris was nominally its capital, the government established itself in the resort town of Vichy in the unoccupied "free zone", where it remained responsible for the civil administration of France as well as its colonies. The occupation of France by Nazi Germany at first affected only the northern and western portions of the country, but in November 1942 the Germans and Italians occupied the remainder of Metropolitan France, ending any pretence of independence by the Vichy government.
