There was sporadic naval warfare in the Mediterranean during World War I between the Central Powers' navies of Austria-Hungary, Germany and the Ottoman Empire and the Allied navies of Italy, France, Greece, Japan, America and the British Empire.

Austria-Hungary was a medium-sized naval power in 1914. It had a coastline from Trieste (in present-day Italy) to below Cattaro in Montenegro. The Austro-Hungarian Navy had nine pre-dreadnought and four dreadnought Tegetthoff-class battleships and a number of submarines. In addition, the Germans managed to send some U-boats to the Mediterranean which operated from Austrian naval bases, initially under the Austrian navy flag, later under the German navy flag.

The Kingdom of Italy during World War I had six dreadnought battleships (Dante Alighieri as a prototype, Giulio Cesare, Conte di Cavour and Leonardo da Vinci of the Conte di Cavour class, Andrea Doria and Caio Duilio of the Andrea Doria class).
