Convoy JW 51B was an Arctic convoy sent from United Kingdom by the Western Allies to aid the Soviet Union during the Second World War. It sailed in late December 1942, reaching the Soviet northern ports in early January 1943.

Convoy JW 51B came under attack by German surface units, engaged in Operation Regenbogen, on 31 December. In the engagement, a British minesweeper and a British destroyer were sunk and a German destroyer were sunk; no ships were lost from the convoy in what became known as the Battle of the Barents Sea.
