'O' (ii) was an Italian convoy operation across the Mediterranean (9/11 July 1942).

One of three single-ship convoys, together with the 'L' and 'N' convoys, this was undertaken from a port in the Aegean Sea to Benghazi in North Africa. The convoys were escorted by the destroyers Folgore, Freccia, Lampo and Saetta, and the torpedo boats Calliope, Orsa, Pallade and Polluce, and all the ships reached their destinations safely.
