Niki (Greek: Τ/Β Νίκη, "Victory") was a 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.
During World War I, Greece did not enter the war on the side of the Triple Entente until 1917 and, due to Greece's neutrality the four "Niki"-class ships had been seized by the Allies in October 1916, taken over by the French in November and served in the French Navy from 1917 to 1918. By 1918, they were back on escort duty under Greek colors, mainly in the Aegean Sea.
"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.
After the war, "Niki" was refurbished from 1925 to 1927. She also participated in the Second World War, first carrying supplies in the Ionian Sea and after surviving the German invasion of April 1941, "Niki" served in conjunction with the Royal Navy based in Alexandria, Egypt. After the end of World War II, "Niki" was stricken in 1945.
