HMS Echo was a 24-gun sixth-rate of the Royal Navy, in active service between 1758 and 1764, during the Seven Years' War.
Originally the French corvette L'Echo, she was captured by HMS Juno in 1758 and refitted as a privateer hunter.
The vessel was originally intended as a privateer named Le Maréchal de Richelieu, but was purchased by the French Navy in December 1758.
Completed in early 1759, she was commissioned into that Navy as the 28-gun corvette L'Echo and assigned to duties in the French Caribbean.
Her crew numbers as a French vessel are unrecorded; the designated Royal Navy complement was 160 men.
