HMS Flying Fish (1803)
 HMS Flying Fish was the American-built schooner Flying Fish launched in 1801. She became the French privateer schooner Poisson Volant which the British captured in 1803 in the West Indies and took into the Royal Navy. She captured a privateer and recaptured some small merchant vessels. She was renamed Firefly in 1807 but was lost with all hands when she foundered later that year.
