HMS Spitfire was a Tisiphone-class fireship of the Royal Navy. She served during the years of peace following the end of the American War of Independence, and by the outbreak of the French Revolutionary Wars, had been reclassified as a 14-gun sloop-of-war. Spitfire went on to serve under a number of notable commanders during a successful career that saw her capture a considerable number of French privateers and small naval vessels. She spent most of her career in Home waters, though during the later part of her life she sailed further afield, to the British stations in North America and West Africa. She survived the Napoleonic Wars and was eventually sold in 1825 after a period spent laid up.

Vice-Admiral Sir Thomas Francis Fremantle, 1st Freiherr von Fremantle, was a British naval officer in the Royal Navy whose accolades include three separate fleet actions, a close friendship with Lord Nelson, and a barony in Austria. He was the father of Admiral Sir Charles Fremantle, after whom the city Fremantle, in Western Australia, is named.
