Mario Giorgini (Massa, 19 March 1900 – Florence, 23 January 1977) was an Italian naval officer during World War II.

[2][3] In July 1940 Admiral Raffaele de Courten, Giorgini's superior, ordered him to select his best four crews and launch an attack on the capital ships of the Mediterranean Fleet moored in Alexandria.

Having set course for Tobruk, Gondar was then located and hunted by HMAS Stuart and HMS Diamond, badly damaged by depth charges and forced to surface, where she was scuttled by her crew.

Along with the crew and the SLC operators, Giorgini was thus captured and sent to a prisoner of war camp in India, where he remained in captivity for nearly six years, only returning to Italy on 21 April 1946.

[7][8] Upon returning from captivity, Giorgini was promoted to captain, later commanding the submarine depot ship Antonio Pacinotti and the light cruiser Giuseppe Garibaldi.
