K' (iii) was an Italian one of a related pair of trans-Mediterranean convoys with 'C' (iv) (22/24 April 1942).

'K' (iii) operated from Tripoli to Naples, and 'C' (iv) from Tripoli to Naples, each with two freighters and escorted by the destroyer Antonio Pigafetta and the torpedo boat Centauro, and the destroyer Nicolo Zeno and the torpedo boat Pallade respectively. As they passed on reciprocal courses, the convoys exchanged their escorting destroyers, and the 'C' (iv) convoy was later reinforced from Tripoli by the torpedo boats Cantore and Montanari and the German minesweepers R 12 and R 15. Both convoys reached their destination safely despite intense British air attacks.
