HMS Unicorn was a 32-gun fifth-rate Pallas-class frigate of the Royal Navy, launched in 1794 at Chatham. This frigate served in both the French Revolutionary Wars and the Napoleonic Wars, including a medal action early in her career. She was broken up in 1815.

HMS Dryad was a fifth-rate sailing frigate of the Royal Navy that served for 64 years, at first during the Napoleonic Wars and then in the suppression of slavery. She fought in a notable single-ship action in 1796 when she captured the French frigate Proserpine, an action that would later earn her crew the Naval General Service Medal. Dryad was broken up at Portsmouth in 1860.
