Carlo Margottini (19 January 1899 – 12 October 1940) was an Italian naval officer during World War II.

He participated in the First World War, first serving on the battleship Conte di Cavour, then on the scout cruiser Nibbio and on torpedo boats.

On 9 July 1940 he participated in the Battle of Calabria, where he led his Squadron in a gun and torpedo attack on the British fleet, receiving for this action the Bronze Medal of Military Valor.

[2][3] Captain Margottini was mortally wounded and died shortly thereafter at his command post on the bridge, while inciting his crew to fight on; his squadron assistant, Lieutenant Corrado Del Greco, was also killed.

Artigliere was sunk later on that morning by the heavy cruiser HMS York, after an aborted towing attempt by her sistership Camicia Nera.
