'EN' was the designation of British coastal convoys (together with a numerical suffix) plying the route between Methil and the Clyde river, later Loch Ewe (August 1940/May 1945).

The series started with EN.1 in August 1940 and was numbered sequentially to EN.95 of April 1941, when the series reverted once more to EN.1 and then continued to EN.493 in May 1945 when the series ended. During 1945, eight convoys sailed to Belfast.

The first of these 595 convoys was EN.1 of 2/5 August 1940 with the 1,620-ton Norwegian Korsfjord, and the last was EN.493 of 17/19 May 1945 with 14 merchant vessels.
