Vettor Pisani was the lead ship of her class of four submarines built for the Regia Marina (Royal Italian Navy) during the late 1920s. She was named after Vettor Pisani, a Venetian admiral. The submarine played a minor role in the Spanish Civil War of 1936–1939 supporting the Spanish Nationalists.

Vettor Pisani briefly had Junio Valerio Borghese as commander during the Second World War. Due to her age, her usefulness was limited, and she saw no real service during the war. The submarine survived the war and was subsequently laid up on 23 March 1947.
