The action of 29 November 1811 was a minor naval engagement fought between two frigate squadrons in the Adriatic Sea during the Adriatic campaign of the Napoleonic Wars. The action was one of a series of operations conducted by the British Royal Navy and the French Navy to contest dominance over the Adriatic between 1807 and 1814. During this period the Adriatic was surrounded by French territory or French client states and as a result British interference was highly disruptive to the movement of French troops and supplies.
