SMS Helgoland was a Novara-class scout cruiser built for the Austro-Hungarian Navy right before World War I. Helgoland participated in several raids on the ships defending the Strait of Otranto, including the Battle of the Strait of Otranto in May 1917. She was transferred to Italy in 1920 in accordance with the peace treaties ending World War I and renamed Brindisi. After modifications, the ship was assigned to the squadron responsible for the Eastern Mediterranean until 1924. She spent the next five years based in Libya and Italy before Brindisi was disarmed and turned into a depot ship in 1929. The ship was stricken from the Navy List in 1937 and later disposed of.
