Russian battleship Imperatritsa Mariya
 Imperatritsa Mariya (Russian: Императрица Мария: Empress Maria) was one of three Imperatritsa Mariya-class dreadnoughts built for the Imperial Russian Navy lead ship of her class. Construction began before World War I and she served with the Black Sea Fleet during the war. She covered older pre-dreadnought battleships as they bombarded Ottoman facilities in 1915 and engaged the ex-German light cruiser Midilli several times without inflicting anything more serious than splinter damage.
