HMS Warrior was a 74-gun third rate ship of the line of the Royal Navy, launched on 18 October 1781 at Portsmouth. A year after her launch she took part in the Battle of the Saintes. In 1801, she was part of Admiral Sir Hyde Parker's reserve squadron at the Battle of Copenhagen, and so did not participate in the battle. In 1805, she was part of Admiral Robert Calder's fleet at the Battle of Cape Finisterre. Later in December of that year she was involved in towing HMS Victory to Spithead. Warrior became a receiving ship in 1818, a prison ship after 1840, and was eventually broken up in 1857.
