Salamis (Greek: Σαλαμίς) was a partially constructed capital ship, referred to as either a dreadnought battleship or battlecruiser, that was ordered for the Greek Navy from the AG Vulcan shipyard in Hamburg, Germany, in 1912. She was ordered as part of a Greek naval rearmament program meant to modernize the fleet, in response to Ottoman naval expansion after the Greco-Turkish War of 1897. Salamis and several other battleships—none of which were delivered to either navy—represented the culmination of a naval arms race between the two countries that had significant effects on the First Balkan War and World War I.
