The La Masa class was a class of eight destroyers of the Italian Regia Marina (Royal Navy) constructed during the First World War, during which one ship was lost in a collision. Like other obsolete Italian destroyers, the seven surviving ships were reclassified as torpedo boats in 1929, and served during Second World War. Two ships were sunk in air attacks while in Italian service during the Second World War, one was sunk by a mine, and two more were scuttled. The remaining two ships survived the war and continued to serve in the post-war Italian Navy (Marina Militare) before being decommissioned in 1957–1958.
