'NJ' was the designation of Allied convoys (together with a numerical suffix) plying the route round the coast of Newfoundland island from Botwood to St John’s, and as such reciprocals of the 'JN' series (June 1942/May 1944).

The first of the 36 such convoys was NJ.1 of 6/7 June 1942 with the 6,090-ton British Pachesham, and the last was NJ.36 of 9/10 May 1944 with the 2,253-ton British Imperoyal.
