Ganges was a ship launched in 1798 at Philadelphia probably for French owners. During the Peace of Amiens her registration and homeport became Dunkirk. Her (possibly new) French owners sent her to engage in whaling at Delagoa Bay, where the British letter of marque whaler Scorpion captured her in 1803. She then made one whaling voyage to Isle of Desolation before a French squadron captured her in 1806 during a second whaling voyage. Accounts differ as to whether her captors sank her, or released her and she continued to operate as a merchant vessel until 1814.
