The title of Duke 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.
