The Unicorn (French: La Licorne) is a fictional 17th-century three-masted armed French Royal Navy vessel appearing in The Adventures of Tintin, the comics series by Belgian cartoonist Hergé. The ship plays a leading role in both The Secret of the Unicorn and Red Rackham’s Treasure, published in 1943 and 1944, respectively. The Unicorn also appears in the 2011 film adaptation The Adventures of Tintin: The Secret of the Unicorn. In the Tintin adventures, the Unicorn is the setting of a battle between pirates and sailors followed by a duel between its captain, Sir Francis Haddock (an ancestor of Captain Haddock) and the pirate Red Rackham. The Unicorn is scuttled and sinks, only to be discovered years later by Tintin and his friends in an attempt to locate Red Rackham’s treasure.
