Niki (Greek: Τ/Β Νίκη, "Victory") was a Niki-class destroyer that served in the Royal Hellenic Navy (1907–1945). The ship, along with her three sister ships, was ordered from Germany in 1905 and was built in the Vulcan shipyard at Stettin. Niki saw action in the Greco-Turkish War (1919–1922). In 1919, she conducted escort missions in the Black Sea carrying Greek refugees from Pontus. Later, while covering the Greek Army's disorganized retreat after the fall of Smyrna on September 4, 1922, Niki's commander, Lieutenant Commander D. Hatziskos was killed by a sniper.
