The Ciclone class were a group of torpedo boats or destroyer escorts built for the Italian Navy which fought in the Second World War.

These ships were built as part of the Italian war mobilization programme and completed in 1942–43.

However, there were three different gun configurations in the class: Units of this class were heavily engaged in escort duties between Italy and Northern Africa, or in anti-submarine patrols.

Some units were still incomplete when Italy signed the Armistice of Cassibile, and were sabotaged by the Italians, or captured by the Germans, completed and reclassified as "Torpedoboot Ausland" (Foreign Torpedo-boat).

Aliseo, with Carlo Fecia di Cossato in command, destroyed eight German auxiliary vessels near the port of Bastia, Corsica.
