Napoleonic looting of art (French: Spoliations napoléoniennes) consisted of the confiscation of artworks and precious objects carried out by French troops and officials in the conquered territories of the French Republic and Empire, including the Italian Peninsula, Spain, Portugal, the Low Countries, and Central Europe. The looting began around 1794 and continued through Napoleon I's rule of France, until the Congress of Vienna in 1815 ordered the restitution of the works.
During the Napoleonic era, an unknown but immense quantity of art was acquired, destroyed, or lost through treaties, public auctions, and unsanctioned seizures. Coins and objects made of precious metals, such as the Jewel of Vicenza and the bucentaur, the Venetian state barge, were melted down for easier sale and transport, to finance French military wages. In the confusion, many artworks and manuscripts were lost in transit or broken into pieces, which were often never reunited, as occurred with the marble columns of the Aachen Cathedral.
