'KN' (i) was the designation of US coastal convoys (together with a numerical suffix) plying the route from Key West, Florida, to New York, and as such reciprocals of the 'KS' series (May 1942/May 1945).

The first of the 216 such 'Key West North' convoys was KN.100 that departed Key West on 15 May 1942 with just one unescorted merchant vessel, and the last was KN.386 of 13/18 May 1945 with 27 unescorted merchant vessels.
