Port au Prince was built in France in 1790. The British Royal Navy captured her in 1793 off Port-au-Prince, Haiti. Her original name is currently unknown, but her new owners named her for her place of capture. She became a letter of marque, slave ship, and privateer cum whaler. In 1806 she anchored at a Tongan island where the local inhabitants massacred most of her crew and then scuttled her.
