Pietro Micca (pennant number MC) was an Italian submarine which served with the Regia Marina in World War II. She was the third ship named after Pietro Micca, the Savoyard soldier who became a national hero for his sacrifice in the defence of Turin against the French troops in 1706. This boat was the prototype for a class of fast, long range submarines with conventional torpedo armament, naval mine laying capability, and useful secret transport capacity. The ship was built at the Tosi shipyard in Taranto. She was laid down on 15 October 1931 and launched on 31 March 1935. The boat fully met design requirements, but was too expensive to be repeated.
