HMS Peruvian was an 18-gun Cruizer-class brig-sloop launched in 1808 at Parson's Yard, Warsash, England. She was the first naval vessel built at that yard. Peruvian captured two American privateers and participated in an expedition up the Penobscot River during the War of 1812. Then she claimed Ascension Island for Great Britain in 1815. She was broken up in 1830.
