Insidioso (English: "Insidious") was an Italian Indomito-class destroyer. Commissioned into service in the Italian Regia Marina (Royal Navy) in 1914, she served in World War I, playing an active role in the Adriatic campaign and seeing action in the Battle of the Strait of Otranto in 1917. Reclassified as a torpedo boat in 1929, she was stricken in 1938. Reinstated in 1941, she was captured by Nazi German forces in 1943 during World War II. She then served in the German Kriegsmarine as TA21 until she was sunk in 1944.
