HMS Spartan was a Royal Navy 38-gun fifth-rate frigate, launched at Rochester in 1806. During the Napoleonic Wars she was active in the Adriatic and in the Ionian Islands. She then moved to the American coast during the War of 1812, where she captured a number of small vessels, including a US Revenue Cutter and a privateer, the Dart. She then returned to the Mediterranean, where she remained for a few years. She went on to serve off the American coast again, and in the Caribbean, before being broken up in 1822.
