The Saint-Michel-de-Maurienne derailment of December 12, 1917 was a railway accident involving a troop train carrying at least 1,000 French soldiers on their way home for leave from the Italian front in World War I. A derailment as the train descended the Maurienne valley on the Culoz–Modane railway caused a catastrophic crash and subsequent fire in which more than 675 died. It is still France's deadliest rail accident to date.
