Convoy JW 54A was an Arctic convoy sent from Great Britain by the Western Allies to aid the Soviet Union during World War II. It sailed in November 1943, reaching the Soviet northern ports at the end of the month. JW 54A was the first out-bound Arctic convoy of the 1943–44 winter season, following their suspension during the summer. All ships arrived safely.

Convoy JW 54A consisted of 19 merchant ships which departed from Loch Ewe on 15 November 1943. Close escort was provided by the destroyers Inconstant and Whitehall, and two other vessels. These were supported by seven Home Fleet destroyers led by HMS Onslow (Captain James McCoy commandinThe convoy was also accompanied initially by a local escort group from Britain, and was also joined later by a local escort from Murmansk.A cruiser cover force comprising HMS Kent (Rear-Admiral Arthur Palliser), HMS Jamaica and HMS Bermuda also followed the convoy, to guard against attack by surface units. Distant cover was provided by a Heavy Cover Force comprising the battleship HMS Anson, the US cruiser USS Tuscaloosa and four US destroyers. Convoy JW 54A was opposed by a U-boat force of five boats in a patrol line, code-named Eisenbart, in the Norwegian Sea. A surface force comprising the battleship Scharnhorst and five destroyers was also available, stationed at Altenfjord.

JW 54A departed Loch Ewe on 15 November 1943, accompanied by its local escort, of three destroyers, and its close escort. Three days later, on 18 November, it was joined by the ocean escort, while the local escort departed. At the same time the Cruiser Force and the Distant Cover Force from Scapa Flow also put to sea, taking station in the Norwegian Sea. The convoy was not sighted by German reconnaissance aircraft, nor by any of the Eisenbart U-boats, and crossed the Norwegian and Barents Seas without incident. On 24 November JW 54A arrived safely at Kola Inlet.

JW 54A was a successful start to the 1943–44 convoy season, with the safe arrival of 19 merchant ships and the war materiel they carried.
