Julienne David (1773-1843), was a French privateer.
Julienne David participated in the Vendée Revolt on the royalist side and was imprisoned, but managed to escape sentence. After having secured a privateer's letter, she persecuted British ships on the English channel from her base in Nantes. In 1803, she was imprisoned in England for eight years. After her release, she returned to France.
A street in Nantes is named after her. She is also the object of a novel.
