The Imperatritsa Ekaterina Velikaya (Russian: Императрица Екатерина Великая, or Empress Catherine the Great) was the second ship of the Imperatritsa Mariya-class dreadnoughts of the Imperial Russian Navy. She was begun before World War I, completed in 1915 and saw service with the Black Sea Fleet. She engaged the ex-German battlecruiser Yavuz once, but only inflicted splinter damage while taking no damage herself. She was renamed Svobodnaya Rossiya (Russian: Свободная Россия, Free Russia) after the February Revolution, but saw no further combat.
