The naval Battle of Sapienza, also known as the Battle of Porto-Longo, took place in 1354, during the Third Venetian–Genoese War. The Genoese fleet under Paganino Doria captured the Venetian fleet under Niccolò Pisani at the harbour of Sapienza or Porto Longo, near the fortress of Modon (mod. Methoni) in southern Greece.
