The Sella-class destroyers were a group of four destroyers built for the Regia Marina (Royal Italian Navy) in the 1920s. Two of these ships fought in World War II and both were sunk after the Italian capitulation to the Allies. The two other ships were sold to the Swedish Navy in 1940 and were scrapped in the late 1940s.

These ships formed the basis for most subsequent destroyers built by the Italians, but were disappointing in service with unreliable machinery.
