The Dukedom of Abrantès was a title of Napoleonic nobility created in 1808 by Napoleon for Jean-Andoche Junot. After the King of Portugal's refusal to join the Continental Blockade, Napoleon I despatched General Jean-Andoche Junot in command of the French invasion of Portugal. General Junot marched through Portugal and set up camp at the city of Abrantes, before advancing on Lisbon. The dukedom, extinct since 1982 upon the death of Maurice, 6th Duke of Abrantès, was never formally recognized by the Portuguese government.
