HMS Merlin was one of the two original Merlin-class sloops that served the Royal Navy during the French Revolutionary Wars. She was launched in 1796 and was broken up in 1803. Her greatest accomplishment was her role as the leading vessel in a motley flotilla of local vessels that defeated a Spanish attack on the British colonists in Honduras at the Battle of St. George's Caye. She later captured a number of small merchant vessels in the West Indies before returning to Britain, where she was broken up.
