Carlo Pinna (Turin, 9 July 1892 – Rome, 22 September 1972) was an Italian admiral during World War II.

He was born in Turin on 9 July 1892 and entered the Royal Naval Academy of Livorno in 1910, graduating with the rank of ensign in 1913.

From 1936 to 1938 he commanded the heavy cruiser Fiume, then the CREM school in Pola and finally the Naval College of Venice.

From his headquarters in Bizerte he oversaw the arrival of supply convoys from Italy during the final months of the Tunisian campaign; in early May 1943, as the fighting in Africa neared its end, he moved from Bizerte to Tunis and then to Kelibia, where on 10 May he boarded with much of his staff the hospital ship Aquileia bound for Italy, where he arrived on 13 May, the day of the final surrender of all Axis forces in Tunisia.

As German forces moved to occupy Italy, Pinna ordered all seaworthy merchant and naval vessels to sail for Allied-controlled ports, and all unseaworthy ships to be scuttled; he was then authorized by Admiral Luigi Sansonetti to leave Genoa, so as not to be captured by the Germans.
