'DK' (ii) was the designation of Allied convoys (together with a numerical and sometimes a literal suffix) plying the route from Durban, South Africa, to Kilindini, Kenya, and as such reciprocals of the 'KD' series (September 1943/September 1944).

The DK.1 convoy of 17/28 September 1943 comprised the 7,266-ton British Bradford City II, 9,977-ton Norwegian Britannia, 8,026-ton Dutch Cleodora, 5,032-ton British Eastgate, 9,397-ton Danish Inge Maersk, 4,164-ton Greek Irene S. Embirikos, 5,175-ton Greek Nikos T and 9,959-ton Swedish Saint Gobain as well as the 700-ton British commissioned rescue tug Prudent. The last known convoy of the series was DK.21C of 6/14 September 1944, but nothing is known of this.
