SMS Grosser Kurfürst (or Großer ) was an ironclad turret ship built for the German Kaiserliche Marine (Imperial Navy). She was laid down at the Imperial Dockyard in Wilhelmshaven in 1870 and completed in 1878; her long construction time was in part due to a redesign that was completed after work on the ship had begun. Her main battery of four 26 cm (10 in) guns was initially to be placed in a central armored battery, but during the redesign, this was altered to a pair of twin gun turrets amidships.
Grosser Kurfürst was sunk on her maiden voyage when she was accidentally rammed by the ironclad SMS König Wilhelm. The two ships, along with SMS Preussen, were steaming in the English Channel on 31 May 1878.
