Motoscafo armato silurante (torpedo-armed motorboat), commonly abbreviated as MAS was a class of fast torpedo-armed vessels used by the Regia Marina (Italian Royal Navy) during World War I and World War II. Originally, "MAS" referred to motobarca armata SVAN (armed motorboat SVAN, Società Veneziana Automobili Navali (Naval Automobile Society of Venice).

MAS were essentially motorboats with displacements of 20€“30 tonnes (depending on the class), a 10-man crew and armament composed of two torpedoes, heavy machine guns and occasionally a 37 mm or 20 mm cannon.

The term "MAS" is an acronym for Mezzi d'Assalto, (assault craft) in the unit name Flottiglia MAS (assault craft flotilla), the most famous of which was the Decima MAS of World War II.
