HMS Cyane was a Royal Navy Banterer-class sixth-rate post ship of nominally 22 guns, built in 1806 at Topsham, near Exeter, England. She was ordered in January 1805 as HMS Columbine but renamed Cyane on 6 December of that year. Cyane had a distinguished career in British service that included the award in 1847 of a clasp to the Naval General Service Medal to any still surviving crew members of either of two actions. On 20 February 1815, she and HMS Levant engaged USS Constitution; outgunned, both had to surrender. She then served as USS Cyane, including a stint on anti-slavery duties, until she was broken up in 1836.
