Convoy PQ 15 was an Arctic convoy sent from Iceland by the Western Allies to aid the Soviet Union during the Second World War. The convoy sailed in late April 1942, reaching the Soviet northern ports after air attacks that sank three ships out of twenty-five.

The Arctic convoys of World War II were oceangoing convoys which sailed from the United Kingdom, Iceland, and North America to northern ports in the Soviet Union – primarily Arkhangelsk (Archangel) and Murmansk in Russia. There were 78 convoys between August 1941 and May 1945, sailing via several seas of the Atlantic and Arctic oceans, with periods with no sailings during several months in 1942, and in the summers of 1943 and 1944.
