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.
A native of Bayonne, Dubourdieu started sailing on a merchantman at 16, before joining the Navy in 1792.
He quickly rose to ensign aboard the Entreprenant.
In the Action of 27 February 1809, along with the frigate Pauline, he captured HMS Proserpine blockading Toulon.
On 23 October 1810, he raided Lissa and captured 6 ships in the harbour.
He was then tasked to capture the island and establish a base there.
Promoted to contre-amiral, Dubourdieu set sail with 6 frigates.
In the ensuing Battle of Lissa, the French were routed and Dubourdieu was killed.
