Laurent de Gouvion Saint-Cyr, 1st Marquis of Gouvion-Saint-Cyr was a French military commander in the French Revolutionary and Napoleonic Wars who rose to the rank of Marshal of the Empire. He is regarded as Napoleon's finest commander in defensive warfare.

Marshal of the Empire was a civil dignity during the First French Empire. It was created by Sénatus-consulte on 18 May 1804 and to a large extent reinstated the formerly abolished title of Marshal of France. According to the Sénatus-consulte, a Marshal was a grand officer of the Empire, entitled to a high-standing position at the court and to the presidency of an electoral college.
