The Battle of Pirano (also known as the Battle of Grado) on 22 February 1812 was a minor naval action of the Adriatic campaign of the Napoleonic Wars fought between a British and a French ship of the line in the vicinity of the towns of Piran and Grado in Adriatic Sea. The French Rivoli, named for Napoleon's victory 15 years earlier, had been recently completed at Venice. The French naval authorities intended her to bolster French forces in the Adriatic, following a succession of defeats in the preceding year.
