Petr Velikiy ( – Peter the Great) was an ironclad turret ship built for the Imperial Russian Navy during the 1870s. Her engines and boilers were defective, but were not replaced until 1881. The ship made a cruise to the Mediterranean after they were installed, and before returning to the Baltic Fleet, where she remained for the rest of her career. She did not, like the rest of the Baltic Fleet, participate in the Russo-Turkish War of 1877–1878. Petr Veliky was deemed obsolete by the late 1890s, but she was not ordered to be converted into a gunnery training ship until 1903.
