HNoMS Thorodd was a Royal Norwegian Navy patrol ship and minesweeper that served through the Second World War, first during the Norwegian Campaign that followed the invasion of Norway in 1940, and then from exile in the United Kingdom. Thorodd was originally built as a steam escort trawler for the French Navy under the name Fleurus, before being sold to a Norwegian whaling firm who leased her to the Falkland Islands Government. SS Fleurus served as a commercial mail ship in the Falkland Islands Dependencies during the 1920s, and was the first vessel to carry paying tourists to Antarctica. Following the war, Thorodd was converted to a fishing trawler and sank in 1955.
