Bernard Dubourdieu (28 April 1773 13 March 1811) was a French rear-admiral who led the allied French-Venetian forces at the Battle of Lissa in 1811, during which he was killed.

The action of 27 February 1809 was a minor naval engagement during the French Revolutionary Wars. Two 44-gun frigates, Pénélope and Pauline, sortied from Toulon harbour to chase a British frigate, HMS Proserpine, which was conducting surveillance of French movements. First sneaking undetected and later trying to pass herself as a British frigate coming to relieve Proserpine, Pénélope approached within gun range before being identified. With the help of Pauline, she subdued Proserpine and forced her to surrender after a one-hour fight.

Proserpine was sailed to Toulon and commissioned in the French Navy, where she served until 1865. Captain Otter remained a prisoner in France until the end of the war; he was court martialed for the loss of his ship on 30 May 1814, and honourably acquitted.
